FORWARD This manual is published as a general guide for the normal care and operation of your NATIONAL-OILWELL Drawworks. Because of the many factors which normally contribute to the proper function or malfunction of this machinery, and not having complete knowledge of each factor or combination of factors, we cannot detail all facets of this subject. We, therefore, confine the scope of this presentation; and when situations encountered are not fully encompassed by complete understandable instructions – these situations must be referred to NATIONAL-OILWELL. When other than routine maintenance or servicing is necessary, it can be most efficiently performed if the unit or primary component is removed from service to an area of adequate space where an over-head crane, hydraulic lift, bearing pullers, impact tools, shelter, etc., are available and readily accessible. The dimensions and tolerances specified in this publication are those desirable for the most efficient operation of the Drawworks. When components become worn or when new parts are introduced into a worn unit, it may not be possible or economically feasible to reestablish such strict alignment and correct all dimensional deviations. Improvements in design, engineering, materials, production methods, etc., may necessitate changes in the Drawworks resulting in inconsistencies between the contents of this publication and the physical equipment. NATIONAL-OILWELL reserves the right to make these changes without incurring any liability or obligation beyond that stipulated in the purchase contract. The pictures, photographs, charts, diagrams, drawings, written contents and specifications contained herein are not to be construed as giving rise to any warranty on the part of NATIONAL-OILWELL. NATIONAL-OILWELL make no warranty, either expressed or implied, beyond that stipulated in the purchase contract.

CAUTION Exercise safety in all performances, do not ignore any cautions, notes of warnings; use only approved methods, materials and tools. Do not permit any function of questionable safety because accidents are caused by unsafe acts and unsafe conditions. SAFETY IS YOUR BUSINESS AND YOU ARE INVOLVED!

! ATTENTION ! Before performing any service function, be certain that the unit is separated from the power source or that the power source is locked-out to prevent any form of energy from entering the equipment. This would include electrical or mechanical energy, into or from the prime/mover(s); pneumatic energy from the compressor/air system, etc. The traveling equipment should be suspended from the hanging line and the mechanical brake released to insure there is no load on the drum that may cause unintended rotation. The sub-assemblies of the unit represent massive weights and must also be suspended being released form operating. WARNING Failure to observe the WARNINGS, CAUTIONS and NOTES in this publication or various industry publications can result in property damage, serious bodily injury or even death! INTRODUCTION A serial number is assigned to each drawworks and any inquiries concerning the drawworks in your possession must include reference to this serial number. The serial number is stamped on the drawworks identification plate; on the frame near the spinning cathead, and again on the corner of the skid at the drillers end. A separate illustrated parts list is provided for ordering replacement parts. It contains any modifications which may have been incorporated after this manual was written. NATIONAL-OILWELL reserves the right to change specifications of subsequent production units of this equipment without incurring liability for such change on previously built equipment. Copies of this manual are furnished with each new drawworks at time of shipment on a “no charge” basis. Additional or replacement copies may be purchased.

INSTALLATION

1.1

Installation Recommendations for rig-up, operation and maintenance of NATIONAL drilling rigs are based on the knowledge and experiences of NATIONAL field engineers and a number of drillers and tool pushers. Following these recommendations will result in better overall rig performance and increased equipment operating life.

1.2

Factory Testing At the factory the complete drawworks is carefully leveled and aligned, the joint plates and dowel pins welded in place, the joint bolts inserted and the drawworks test run. All mechanical and air control systems, the lubrication system, and all brakes and clutches are test operated and checked. Each drawworks functions perfectly before it is released for delivery to user. Guards cover all moving parts. These guards serve several purposes; for example, they serve as enclosures for the oil lubrication system, provide safety for personnel, and prevent foreign material from getting into the working parts. Keep guards bolted in place when the drawworks is in operation. Keep inspection doors closed except when lubricating or inspecting.

1.3

Material Check A general check of all materials shipped to the rig-up site should be made as soon as possible to determine if any damage has occurred during shipment. Visual inspection should be made of all skids, guards and other equipment that is unprotected and which could receive a blow during shipment. Damage should be inspected in the light of what might have been damaged but not immediately apparent form outside inspection. Any damage should be immediately corrected. It is much easier to correct damage to piping, skids, etc., while the individual units are on the ground than after the unit has been set on the substructure. Any damage to the main skids would undoubtedly cause errors I alignment if they are rigged up without correction. Small items that are boxed separately for shipment should be examined for rough handling to make sure the parts are not damaged or lost.

1.4

Foundation Drawing A foundation drawing is furnished for every rig to coordinate installation of various components. All dimensions, clearances, positions, etc., of the equipment are shown on this drawing. It is used by the substructure manufacturer to build his substructure. If the rig is enclosed this same drawing is used by the house manufacturer to design the house. This drawing is the key to a rig up.

EPL-1439 03 10

The main dimensions on a foundation plan are the well centrelines. All pertinent dimensions used at rig up are shown on the foundation plan and are dimensioned relative to the centrelines of the well. As an example, after the substructure is erected the first thing needed is the distance form the centreline of the well to the drum shaft. This is given on the foundation plan. It also shows the distance of the drawworks either side of the center line of the well (to the driller’s side, to the rotary side). All dimensions needed to locate any given piece of equipment will appear on the foundation plan. 1.5

Assembly and Alignment – Drawworks Most NATIONAL drawworks are sectionalized to facilitate transporting. Each section should be handled separately. Do not attempt to lift sections dowelled together. When sections are assembled on substructure, place dowel pins all the way into their mating plates and draw up tight, with the large bolts provided for this purpose. The assembled drawworks should be skidded using jacks during final positioning operations. Align the assembled drawworks with the centerline of the well to dimensions shown on the foundation drawing. The front and rear base beams of drawworks frame are marked with arrows to show the centerline of well. Do not confuse the two marks on the front of the drawworks. One of these marks the centerline of the well and the other marks the centerline of the drum. Both centerlines appear on the foundation drawing and care should be taken that the centerline of the well is used. Secure the drawworks to the substructure. If rods and turnbuckles are used, place one at each end of the drawworks, under the drum shaft bearing supports. Use1½” turnbuckles or larger. Most installations will require that these turnbuckles be cut and a1½” rod welded in to make them long enough to reach into the drum section and down to the substructure. This allows the drum section to be held tightly against the substructure to prevent vibration during hoisting operations. The drawworks skid beams should be tied to the substructure beams with clamp plates, as bolts require drilled holes in the beams. NOTE: On permanent installations (offshore rigs) the drawworks beams can be welded to the substructure. If substructure steel is not flat and true, shimming should be used between contact areas of the drawworks skid beams and the substructure beams. Precaution should be taken so as not to distort the drawworks frame when tying down, since factory alignment was made on a level true plane surface. Particular attention should be given to good, even support under the auxiliary brake zone of the drawworks frame. Install all inter-connecting, pre-aligned, air, oil, and water lines; mechanical linkage and roller chains. Avoid pockets or bends in air lines which may accumulate moisture. Control devices will compensate for moderate pipe leakage but loss of air causes unnecessary demand on the air supply. NOTE: When rigging down, all inter-connecting lines should be re-plugged, capped, or taped, to keep free of dirt and other foreign matter.

EPL-1439 03 11

Alignment – Rotary Table The rotary table should be installed with the center of the table opening aligned with the centerline markings on the substructure. This can usually be done by inserting a board in the square of the table and laying out the accurate center of the opening. This line can be extended until it intersects the centerline of well arrows on the substructure. Securing the rotary table to the substructure can be accomplished by several methods. On the most common mounting the table is located by stops and tied down to the substructure with turnbuckles. Usually four 1½” turnbuckles are used. Another method is one in which the table is free to move upward. For this installation tall stops that allow about six inches are used without tie downs. The rotary drive chain length is not always specified on the foundation plan. Therefore, install only the number of links of chain that will fit the drive. It is not necessarily a tight chain as on the other drives throughout the drawworks and rig drive units. The guard, which is normally an oil bath guard type, should be installed before the rotary table is set in place.

1.7

Assembly and Alignment – Rig Drive The approximate location of the No. 1 engine section can be determined from the foundation plan. However, due to manufacturing tolerances in the welded steel substructure, it is impossible to locate No. 1 engine sections by dimension only. Therefore, it is recommended that the No. 1 engine section be located an inch or two closer to the drawworks than the dimensions on the foundation plan indicates. The drawworks drive sprockets should then be aligned accurately with a then copper wire or a straight edge. After the No. 1 section is aligned to the sprockets, stops should be tacked to the outside substructure beams tight to the front engine from skid. Also stops should be tacked underneath the engine skids to act as guides against the substructure so that the No. 1 section can be jacked back in a straight line. After this is accomplished the drawworks drive chain should be installed, and by measuring from the stops on the substructure to the front of the No. 1 skid the engine frame can be jacked evenly until the drawworks drive chain is tight. This procedure will maintain the sprocket alignment, which is extremely important as any misalignment leads to excessive chain, sprocket and bearing wear and materially adds to maintenance costs. Chain manufacturers have provided a measuring guide to proper chain tension, which may be used where, not established by factory alignment. As a general rule, when all chain slack is measured on one side of the sprocket, the vertical sag should not exceed two percent of the distance between shafts or sprocket centers.

Due to the design of our section drive group, after the No. 1 section is aligned with the drawworks it is only necessary to remove the shipping covers from the compound guards and the necessary floor plate to get at the joint block bolts. After this the remaining sections can be pulled into place and the bolting of the sections together automatically brings them to the same alignment as when they were manufactured at the factory. If time has not been taken to dowel the No. 1 section to the substructure it is a good idea to tack the No.1 section to the substructure so it is not pulled out of alignment when the remaining sections of the rig drive are installed. As in the case of the drawworks, clamp plates rather than bolts are recommended for securing the engine frames to the substructure. Control air lines are connected between engine frames by short jumper hoses. These hoses are located between the engine skids under the removable floor plate. The lubrication oil line for the oil spray pipes is connected by short jumper hoses located at the breaks in the compound guards above the floor plate. On rig drives equipped with National hydraulic couplings it is necessary to connect the cooling water lines from the heat exchangers. This is done with a 3” Dresser sleeve coupling between each engine frame. 1.8

Wireline Spooling NATIONAL drawworks feature large main drums with two-step spiraled grooving. Assuming 8 lines strung and 90’ stands, less than three full layers of line will be spooled on the drum when the traveling or hook block is in its uppermost position. When stringing the blocks for the first time we recommend seven anchor coils be spooled on the drum when the elevators are in position to hoist pipe.

1.9

Lubrication As soon as the drawworks has been completely assembled and ready for initial running, the following steps should be taken: 1.9.1 Lubricate all grease fitting per instructions outlined in Lubrication Section. 1.9.2 Make sure the oil sump is clean, then fill with oil – see Lubrication Section for oil specification. A bayonet type filler gauge is located in the sump for measuring the oil level. When the drawworks is running there should be sufficient oil in the reservoir to cover the strainers. 1.9.3 Check the chain lubrication by opening the doors on the back of the drawworks. The spray system should deliver a stream of oil to all chains, mechanical clutches, and gears.

EPL-1439 03 13

Operation of the drawworks is dependent on an adequate air supply for operation of the catheads and all air clutches. With air compressor operating properly, blow-out all air lines supplying control cabinet, clutches and catheads. Following this check to see that all air lines are open and gauges are active. The pressure gauge in the drawworks control cabinet marked air supply should read approximately 110 psi. Open and close the control valves for the high and low drum clutches, the rotary drive clutch, inertia brake, coring reel clutch, and both catheads. Listen for the exhaust of air from each clutch through the quick release valve when the control valve is closed. Do not operate the drawworks unless these quick release valves work properly. All air clutches on the drawworks are controlled by pressure graduating type air valves. Engage air clutches with an even motion of the control valve lever to the “ON” position. Abrupt engagement of air clutches causes excessive loading on shafts and chains. Too slow engagement will over-heat clutch elements due to excessive slippage. Hand operated clutches should be actuated with the same smooth engagement and feel as the foot operated clutch of an automobile. To be sure air gets in and out of the clutch quickly, keep the regulating valve and release valve in good condition. Air clutches should be inspected periodically for lining wear. Refer to Maintenance Section for allowable lining wear on NATIONAL clutches. 1.11

General Inspection When the drawworks is moved from one location to another, or taken from storage into the field, every precaution should be taken to insure the equipment is in first class operating condition. These suggestions will be helpful and may suggest others to the crew. Check alignment of sprockets, bearings, and shafts. See that all bolts are tight, particularly those already made up and therefore not installed during rigging up. Inspect all chains for wear or damage, replace entire length rather then attempting to make repairs or replacing broken links. Check all air connections and hoses for leaks. Replace any broken or damaged air hoses and fittings. Check operation of air valves – clean, replace, or rebuild as required. Engage and disengage air clutches to see they will operate smoothly without slippage or overheating. Check shifter control rods and linkage to insure proper operation of the drawworks transmission clutches.

Clean oil sump in drawworks and clean the suction screens to insure free oil flow Check installation of chain guards so the oil will have unrestricted flow back to the sump. Replace any fittings that will not take grease. Replace broken or pinched grease tubing. Clean and replace plastic bowl on main air line filter. If drawworks is equipped with air line lubricator, remove plastic bowl, clean and refill with oil. Inspect pump in the lube system. Adjust distributors for flow of oil. Be sure nozzles are not clogged on spray system. With the drawworks running, check the main bearings on all shafts, see that they are well lubricated and securely bolted down. Check the water supply system to make sure it is delivering sufficient water to the brake rims and the auxiliary brake. Check spear connections to the drum shaft and auxiliary brake to see that the packing is in good condition and not leaking. If any part is worn beyond operating safety or efficiency, the time to find and replace it is during rigging-up operations. Thorough inspection for worn or broken parts and prompt replacement are good insurance against major repairs.

LUBRICATION

2.1

General NATIONAL equipment is designed to use oils and greases which are generally available from most oil companies and their distributors. The benefits from certain special or premium type lubricants may not justify their extra cost. In general the most important factor in lubrication is the systematic application of recommended lubricants at regular intervals to assure trouble free operation. Particular care should be exercised in following the lubrication instructions issued by manufacturers of engines, pumps, power takeoffs, air compressors, couplings and similar units which are operating components of the rig. The large number of suitable oils and greases makes it impractical to list them by their brand names. We therefore give general specifications. Most oil company salemen and distributors will have no trouble in supplying products to meet these specifications.

2.2

Oil Types The SAE viscosity numbers perhaps need some explanation. They were established to give a slight measure of standardization to the specification of automotive crankcase and transmission oils. These numbers have since been proven to be a convenient way designating oils for general use. Each number covers a certain viscosity range at a specified temperature. The number tells nothing about the type of base stock (naphthenic or paraffine) and nothing about the presence or absence of additives. Oils having SAE numbers 5W through 50 are classed as motor or crankcase oils and the numbers 75 through 250 are classed as gear oils or transmission and axle lubricants. Oils in either classification may be furnished with no additives of any kind. When additives are used however, those in motor oils will generally be different from those in gear oils. Gear oils carry higher numbers than motor oils but the viscosities are not necessarily higher than for motor oils. SAE 50 motor oils, for example is within viscosity range of SAE 90 gear oil. In addition to SAE numbered oils, most oil companies make a number of oils which may be designated by their prime usage. This category includes turbine oils, certain gear oils, etc. The viscosity for these is generally given in Saybolt Universal Seconds (abbreviated SUS) at a stated temperature.

EPL-1439 03 16

Chain Lubrication A straight mineral oil is generally satisfactory, but rust and oxidation inhibitors may be beneficial additives. Detergent oils may cause trouble by forming an emulsion in the presence of water and should therefore be avoided. The proper viscosity to use will depend primarily upon the operating temperature of the oil. An unenclosed rig running in cold weather requires lighter oil than one that is better protected. The following table may be helpful in selecting the proper oil viscosity. Note that there is some overlap in the temperature range. Between 80°F and 100°F (27°C - 38°C) for example SAE 30 and SAE 40 oils are equally satisfactory. Oil Viscosity SAE 40 SAE 30 SAE 20 % 20W SAE 10W

2.4

Ambient Temp. Range 80° F (27°C) or higher 50°F - 100°F (10°C-38°C) 30°F - 60°F (0°C-16°C) 30°F (0°C) or lower

Cascade System A pressure spray system delivers a stream of oil to each chain and gear tooth clutch located in the chain housings. A positive displacement oil pump, chain driven from the main drive shaft, delivers the pressure controlled oil. This system is completely enclosed, with the oil constantly returning to a large volume sump for recirculation. Each distributor valve is set to provide adequate flow during run-in testing at the factory. The rate of flow should be re-checked in the field with the rig running at idling speed. A pressure gauge located at the driller’s position monitors oil system pressure. If high pressure results from reducing the flow at distributor points, relieve pressure by adjusting the relief valve on the pump, permitting excessive oil to drain back into the sump. Good balance between pressure and quantity delivered to the distributors’ results in higher pump efficiency and minimum of wear on pump working parts. Should the pump become worn, or the pump shaft break, it is more economical to replace the pump than to repair it. The oil sump should be checked daily to see that the oil level is sufficiently above the strainer for safe operating margin. Drain the sump each thirty (30) days and refill with new oil, or change whenever oil becomes contaminated, whichever occurs first. Clean suction strainer at each oil change. CAUTION: Oil in the cascade system may in time become emulsified and lose its lubricity. Observe oil flow out of the distributor valves and if these streams appear yellow or foamy, drain and refill with new oil immediately.

Grease Greases are classed according to the kind of thickener which is added to convert oil into grease. Greases thickened with sodium soap are known as sodium base greases and those thickened with calcium soap are known as calcium base greases. Sodium base greases have long been the standard for anti-friction bearing in which the temperatures run over 200°F. Most sodium base greases have poor water resistance so that past practice has been to use a water stabilized calcium base grease (which breaks down at high temperature) in applications exposed to water as on the hydromatic brakes. There are several varieties of multi-purpose grease which combine the temperature resistance of sodium base grease with the water resistance of calcium base grease. Some of these are mixed sodium and calcium base, some are lithium based and some use solid or synthetic thickeners. These multi-purpose greases cost more than a standard grade of sodium or calcium base grease, but they make it possible to have just one kind of grease on the rig. Grease consistency standards have been established by the National Lubricating Grease Institute. For rig use, the No. 2 grade should be used in moderate to warm weather and the No. 1 in cold weather. All bearings, control mechanisms, and external gear tooth clutches are greased lubricated through plainly marked and easily accessible fittings.

2.6

Miscellaneous Lubrication Alemite System – Generally speaking, any good sodium base roller bearing grease or multi-purpose grease is suitable for use in all alemite fittings on the drawworks. The grade may be either No.1 (light) or No.2 (medium) depending upon the type of grease gun employed and the climatic conditions under which the rig operates. It is recommended, however, that the grease used have a flow point of 120°-140° F, and a melt point of 300°340°F. Unless otherwise indicated, every alemite lubrication point should be greased once every tour during rig operation and following the first and all subsequent rigging-up jobs. All alemite fittings have been made as easily accessible to the crew as possible so that no lubrication point need be overlooked. Please refer to the lubrication chart for further details. Catheads – Alemite fittings are provided for lubrication of the catheads bearings. Grease fittings once every week – no more than two shots from the gun. Excessive grease migrates to the friction clutches and impairs operation of the catheads.

Rotorseals – The rotorseal is a positive seal for introducing air under pressure to a rotating shaft. Air is transmitted through the shaft to the air operated clutch. Rotorseals are sealed and lubricated for life by the manufacturer. Control Cabinets – Air and manual operating linkage located in the main and auxiliary control cabinets require lubrication at least every week and much more frequently in damp climates. The levers are accessible from the front of the cabinet, while removal of the bank panel is necessary to make the linkage accessible for lubrication. Using a hand oiler filled with SAE #20 motor oil, apply oil at all pivot points. Over-Running Clutch – The best lubricant is a straight mineral oil, either SAE #50 or SAE #90. No compound oils of any kind are recommended, although rust and oxidation inhibitors would be acceptable. The over-running clutch depends on friction for its action, and compounds increasing the lubricity of the oil tend to interfere with its proper operation. Refer to the over-running clutch service manual for detailed information. Hydromatic Brake – When a hydromatic brake is furnished with the drawworks, a #2 (medium) calcium base (water resistant) grease should be used for lubrication. Special button head alemite fittings on the hydromatic brake require the use of a special gun furnished with the brake. Elmagco Brake – Lubrication of the electric brake, when furnished on the drawworks, is accomplished through two alemite fittings using the same good grade of grease as is used on the rest of the drawworks. This will lubricate the roller bearings upon which the stub shaft and drum rotate. NOTE: With this equipment, as with other components manufactured by others than The Machinery and Equipment Division, refer to the applicable operating and maintenance manual for more detailed lubrication information. 2.7

Special Lubricants There are times when a special type of lubricant is justified. Some of the super premium greases have excellent low temperature properties. In extremely cold weather it may be well to use one of these for the weight indicator and possibly the blocks. Rusting and corrosion of the bearings, chains, sprockets, etc., generally presents no problem when a rig is running, but it may become very serious when a rig is stored for a long time in a damp environment. Ordinary oils and greases give only moderate protection so that special compounds may be well worth while.

EPL-1439 03 19

Some of the super premium greases give very high corrosion protection. Applying one of these to every fitting in quantities sufficient to flush out most of the old grease will go a long way toward protecting the equipment during storage. For protection of chains, sprockets, chain casings, etc., against rust during prolonged storage, it is best not to rely for protection on the oil that was clinging to the parts when the rig was shut down. Use a compound designed for this purpose and apply it according to the manufacturer’s recommendation. In selecting a material it is best to use one that does not require any special cleaning before the rig is run again. There are compounds that will be flushed away by normal lubricating oil and mix with it harmlessly For additional lubrication information please refer to the lubrication chart in the illustrated parts list.

CONTROLS AND AIR SYSTEM

3.1

Controls - General Drillers consoles on all National mechanical drawworks are basically the same with a main control cabinet located at the drillers position. This cabinet houses air controls for drum clutches, rotary clutch, catheads, master clutch and inertia brake as well as air controls for engine throttle groupings. Manually operated controls for the drawworks transmission are located in a convenient position on the front of the main control cabinet. An auxiliary control cabinet, located adjacent to the main control cabinet, provides air controls for core reel clutch, drive group engine clutches of hydraulic scoop controls, pump clutch, and hydromatic brake water level control units (if required). Air pressure gauges are provided for all important control functions. The auxiliary cabinet also houses control valves for cooling water to the brake rims and auxiliary brake. Consoles for electric driven drawworks contain air controls for drum clutches, rotary clutch, catheads, and rotary inertia brake (1320-UE, 1625-DEonly). Necessary support is provided for the electric control cabinet for rig motor and generator assignments. Manually operated controls for the drawworks transmission are located in a convenient position on the front of the main control cabinet. Auxiliary control cabinets for electric rigs include various control options for engine throttles, independent pump drives, independent rotary drive, etc., as required by particular rig specification in addition to the cooling water control and hydromatic water level control unit. A load rating plate tabulating maximum recommended hook load for each drawworks speed ration is attached on the front face of the auxiliary control cabinet of all drawworks, thus providing the driller with a convenient guide to proper clutch selection for the most effective rig operation. The foot throttle, emergency low jaw clutch foot pedal, main brake, and core reel brake levers are positioned for maximum convenience.

3.2

Miscellaneous Controls All Drawworks

3.2.1 Water Supply Valves – Two water inlet connections supplying cooling water for brake rims and auxiliary brake are located in the channel face on the drillers side of the drawworks. A 2” inlet is provided for the auxiliary brake and a 1½” inlet for cooling the brake rims. The flow of cooling water circulating through the brake rims and auxiliary brake is obtained by variable opening of the proper gate valve located at the drillers position.

3.2.2 Main Drum Brake Lever – Actuates the main drum brakes. To set the brake the operator pulls the lever down. Normally the brake lever should be at an angle of 35° with the horizontal when the brake bands are fully engaged on the brake rims under load. 3.2.3 Coring Reel Brake Lever – This brake is set by pulling the lever toward the operator. A ratchet provides means for setting the brake. 3.2.4 Engine Control Foot Pedal – Depress the pedal to accelerate the engines during hoisting operations. This mechanism is spring loaded and the engines will automatically return to idling when the foot is removed. 3.2.5 Auxiliary Low Jaw Clutch Foot Control – (1320-UE/M, 1625-DE/M only). This foot pedal engages the emergency low jaw clutch. Use it in the event of failure of the “low” drum clutch. To make the pedal operative, raise the access door in the floor adjacent to the pedal and connect the pedal arm to the shaft lever with the ¾” cap screw provided. Depress the pedal to engage the jaw clutch within the low drum clutch. For electric drawworks – stop motors before engaging this clutch. For mechanical drawworks – master clutch must be disengaged before engaging jaw clutch. 3.3

Air System

3.3.1 General The air control system is completely adjusted before the drawworks leaves the factory. Plugs are placed in the open ends of all air lines to prevent dirt or foreign material from entering during shipment. In any system where air is compressed there will be a certain amount of condensation. This condensate will cause no trouble if it is discharged from the air system at frequent intervals. This surplus moisture should be discharged at least once every 24 hours by opening the bleeder valve located directly beneath the air reservoir. Air and moisture should be discharged until very little moisture can be detected escaping with the air. Close the valve and allow the pressure to again build up in the system. Care should be taken to keep all parts of the air system in proper adjustment. Many difficulties can be traced to maladjustment of these components. Some of the elements may cease to function properly due to long wear, disassembly of parts, or other conditions. General description, application, and maintenance for these parts will be found on the following pages. 3.4

Westinghouse “H” Control air Valves

www.nov.com

Document number Revision Page

EPL-1439 03 23

The H-2-FX Control air valve is a self holding hand lever operated, three-way normally closed valve for one pressure regulated circuit. It is equipped with an adjustable friction brake that will hold the handle in any position in which it is placed. The H-2-LX Control air valve is a self returning hand lever operated, three-way normally closed valve for one pressure regulated circuit. The lever automatically returns to the valves “neutral” or “off” position from all positions except the extreme travel position when the operating force is removed. The H-3 Control air valve is a self regulating three-way pressure control valve designed for accurate control of air pressure by mechanical operation. A cam actuates the valve to increase, decrease, or maintain delivery pressure in graduated increments. The H-4 Control air valve is a self regulating three-way, pressure control valve. The control knob is manually operated to increase, sustain, or decrease air pressure and is self holding in all positions. Application: See Chart 3.4.1 Maintenance (H-2, H-3, H-4) – Maintenance periods should be scheduled in accordance with frequency of use and working environment of the Control air valves. One complete Control air valve should be kept in stock for each four valves in service. During the maintenance period change out the complete valve with the “stand-by” unit. This will reduce production loss and afford inspection and replacement of worn parts at a more opportune time in a favourable location The operating portion of the valve can be removed without disturbing the pipe connections by loosening studs and lifting the valve free. No special tools are required to maintain the Control air valves. Completely disassemble the Control air valve. Wash all metal parts in a non-flammable solvent and all rubber parts with soap and water. Rinse each part thoroughly and blow dry with a low pressure air jet. Arrange the part on a clean white surface. Examine each part carefully. Flex the diaphragm and packing rings, if cracked or worn replace them. Replace all parts that may not provide satisfactory service until the next scheduled maintenance period. Reassemble the valve, lubricating each part before it is put into place. Use No. 107 Lubriplate on all metal to metal surfaces and Cosmo lube on all rubber parts. Equivalent greases to those recommended can be used. Store the reconditioned Control air valve in a moisture proof bag. 3.5

Westinghouse “H” Relay Valve

www.nov.com

Document number Revision Page

EPL-1439 03 24

The H-5 Relay air valve is a three-way valve which functions as a non-graduated relay to provide a large flow of air from a separate source when piloted by a small amount of control media and to stop this flow and exhaust the air to atmosphere when the control pressure is vented. The valve also acts as an interlock to govern the flow in one circuit by placing its control in another independent circuit. Application: See Chart 3.5.1 Maintenance: Every six months (more often if conditions warrant) remove the valve portions from the pipe bracket and disassemble for cleaning, inspection and lubrication. One complete valve should be kept in stock as a “stand by” for change out during this maintenance period. After disassembly, clean all metal parts with a non-flammable solvent and wash all rubber parts with soap and water. Rinse thoroughly and blow dry with a low pressure air jet. Replace those parts which hare damaged or worn, giving particular attention to the diaphragm and “O” ring. Reassemble the valve, lubricating each part before it is put into place. Use No. 107 lubriplate metal to metal surfaces and Cosmolube on all rubber parts. Equivalent greases to those recommended can be used. Store the reconditioned valve in a moisture proof bag. 3.6

Westinghouse Quick Release Valves: The Quick Release Valve shortens the time required to vent air pressure from a cylinder or other pneumatic devices after an application. This is accomplished by exhausting the air pressure direct to the atmosphere at the quick release valve instead of back through the controlling device. Application: See Chart.

3.6.1 Maintenance: One complete quick release valve should be kept in stock for each four in service. During the scheduled maintenance period, replace the valve in service with the “stand by” unit. Disassemble the valve for inspection, cleaning, and lubrication. Clean all metal parts with a non-flammable solvent and wash all rubber parts with soap and water. Rinse thoroughly and blow dry with a low pressure air jet. No lubrication is necessary, and no special tools are required.

3.7

Westinghouse Shuttle Valve:

EPL-1439 03 25

The Shuttle Valve automatically selects and directs the flow of air form one or the other of two controlling devices to a common outlet. It services to connect two independent lines to a common line without destroying the segregation. Application: See Chart 3.7.1 Maintenance: One complete shuttle valve should be kept in stock. During the scheduled maintenance period, replace the valve in service with the “stand by” unit. Disassembly, inspection, cleaning, and lubrication should be in accordance with the instructions covering the quick release valve. 3.8

Bellows-Valvair Valve: The Bellows Valvair valve is a panel mounted three-way normally closed valve with a spring ball detent arrangement which prevents the stem from drifting when subjected to severe vibration. Application: See Chart

MAINTENANCE

4.1

Air Clutches

EPL-1439 03 40

The key to long life in an air clutch is getting air into and out of it as fast as possible. If air pressure is too slow in building up, the clutch will slip too much before it is engaged fully. If air pressure is too slow in releasing, the clutch will drag before it is completely disengaged. Either of these conditions will result in glazed friction surfaces and overheating. If it continues long enough, the clutch will lose its efficiency, the rubber diaphragms will break down, and on plate clutches, the plates will warp. To be sure air gets into and out of the clutch quickly, keep the regulating valve and release valve in good condition. 4.2

Drum Clutches National Dy-A-Flex air clutches are featured as standard equipment on all drawworks. They are completely self-adjusting and automatically compensate for lining and friction drum wear. Normal operating pressure is 100 to 110 psi. Their design makes possible the replacement of any wearing part except the diaphragm by removing one of the side plates. Replacing the diaphragm requires the removal of both side plates.

4.3

Inspection 1. Repair leaks in air lines or rotorseal immediately, since condition reduces efficiency and life. 2. Oil on the friction surface or on the diaphragm reduces efficiency. Solvents may be used to clean oily clutch parts. 3. Periodically check condition of friction shoe assemblies, diaphragm, and clutch drum. 4. Friction lining should be replaced after the friction material has worn to thickness shown on chart. Add ional wear may cause the lining to break in two at the notch for the lining bolts.

4.4

Lining/Diaphragm Replacement 1. 2. 3. 4.

Plate Clutches The National 36-C and 42-B multiple plate or disc type air clutch is standard equipment on the 1320 and 1625 series drawworks low drum drive. This clutch employs a diaphragm to apply axial pressure directly against the four friction surfaces. The outside diameter of the clutch housing is small enough to permit removal of the drum brake rims without disassembling any part of the clutch itself. In addition, the clutch is mounted outside the drum shaft maing bearings, permitting complete accessibility and simplifying air connections. Maintenance is seldom necessary on this clutch. Normal friction plate wear is automatically adjusted by increased piston travel and there are no levers, toggles, pins, or control linkage to get out of adjustment. On release of clutch, the friction plates are separated and spaced by means of heavy return springs. Instruction for Disassembly and Repair 1. Remove necessary guards. 2. Disconnect air connection hose (1) and water connection hose (2). 3. Remove cap screws (3) which secure the air and water connection assembly to the clutch housing cover. 4. Remove air and water connection assembly (4) 5. Remove hexagon nuts (5 and 6) so that housing cover (7) can be taken off and set aside. Replace the “O” ring (8) before assembly. 6. Unscrew the hexagon nuts (9) so that diaphragm ring (10) can be removed. 7. Pull diaphragm (11) and diaphragm retainer out and check condition of the diaphragm. If it is badly worn or cracked, it must be replaced. 8. Unscrew hexagon nuts (13) so that the diaphragm retainer (14) and diaphragm (15) may be removed. If the diaphragm is badly worn or worn or cracked it must be replaced. 9. Remove cap screws (16) and housing ring (17). 10. Slide the clutch pressure plate assemble (18) out and lay it aside. 11. Remove springs (19). These must be checked and replaced if they are broken or have lost their tension. 12. Slide friction plate (20) and 23), center plate (21) and back plate (24) out of the housing. Check the springs (22) and replace if they are broken or have lost their tension. Reline or replace air clutch disc assemblies and replace any other parts which show signs of excessive wear or breakage.

Lining wear can be checked by measuring the movement of drain nipple part No. 622856-A in the clutch housing (part No. 622856-A for the 36-C and part No. 619258-A for the 42-B). When the clutch is new the drain nipple moves 3/16” from disengagement to engagement. When the drain nipple movement is 9/16” from disengagement to engagement we suggest relining the clutch plates as soon as possible. 4.7

Friction Shoe Replacement Friction shoes should be replaced after the friction material has worn down more than twothirds of its original thickness*, or when their condition is such that a small amount of addition wear could cause friction shoe metal backing plates to score the clutch friction drum. Any air-operated clutch with worn friction shoes requires an additional amount of air on cyclic duty. *Refer to chart.

4.11

To Change Shoes 1. Remove friction shoe pin lockwires, and withdraw shoe pins. 2. Old friction shoe assemblies can then be removed from the clutch element. Necessary clearance may be obtained by first separating actuating element and mating friction drum. 3. Place new friction shoe assemblies in position; insert shoe pins so holes in the ends are in position to take lockwires. 4. Slide lockwires through holes so that scallop of bend in wire points outward from shaft on which clutch is mounted. Bend each end of wire inward toward clutch shaft. Use only top grade wire of proper gauge to fit shoe pin holes. In detaching clutch element, do not lose rubber washer which seals the air passage between the clutch element and mating part.

Brakes Main Drum Brakes – All band type brakes function by transforming the energy of moving loads into heat by the frictional resistance developed between the brake rim and lining. Water to the brake rims is introduced to the drum shaft by means of an “Air and Water Connection Assembly” attached to the drillers end of the drum shaft. Air to the “low” clutch passes through the center of the connection body and the brake rim water enters a stationary bronze housing – then into the water passage of the rotating body. Ball bearings are used to pilot the housing on the body and lip-type seals are used to keep water out of the bearings. Weep holes are provided in the housing between the seals to allow water to run out if the seals begin to leak. The seals should be lubricated daily and should be replaced as soon as any leakage is noted. The cooling water inlet connections are located in the channel face on the drillers side of the drawworks. Two inlets are provided; a 2” inlet for the auxiliary brake, and a 1 ½” inlet for cooling the brake rims. A globe valve is provided in each line to control the water flow rate. On the 1320-M/UE and 1625-M/DE drawworks, which have plate type low clutches, a short, tubular, inlet water spear connects the water passage in the connection body to the water passage in the drum shaft. Good maintenance of the spear tube seals and packer should be established to prevent water from getting into the plate clutch. A weep hole provided in the body flange will drain off minor water leakage through the spear seals. However, the seals should be replaced as soon as possible after any evidence of leakage is observed. On the 55, 80-B/UE, and 110-M/UE drawworks the water connection body attaches directly to the drum shaft and there is no chance of water leakage into the “low” Dy-A-Flex clutch. The brake rim water is discharged from the off-driller’s end of the drum shaft through a special spear, which first passes through the bore of the auxiliary brake shaft before it engages the rubber packer in the end of the drum shaft. The packer should be maintained in good leak proof condition in order to protect the auxiliary brake disconnect clutch from being rusted by leakage. The bronze water inlet housing mounted on the spear uses the same seals as used on the driller’s end connection. Under normal conditions the brake rims will have ample cooling with 15 to 30 gallons of water per minute circulating through them.

EPL-1439 03 49

Separate discharge lines from the brake rims and auxiliary brake are recommended and the water flow from these lines be visible to the driller. With this arrangement the discharge from one system cannot cause a build up of backpressure in the other, and the driller will always have a positive indication of the water flow in both systems. For specific details and part numbers, see the drawworks illustrated parts list pages covering air and water connections and auxiliary brake installation. Auxiliary Brakes – A separate cooling water inlet connection adjacent to the brake rim inlet connection is provided for the auxiliary brake. The source of water is usually the same as for the drum brake rims and a valve is provided at the drillers position to adjust the water flow. Water enters the brake through the inlets on each side of the brake at the bottom or sides and circulates out the top, returning to the supply tank for re-circulation. The braking power and speed of hydromatic brakes is dependent on the level of water in the brake when it starts up, and the rate of flow (gpm) supplied to the brake inlet connection. A water line directly connected to the hydromatic is the simplest system but it cannot be used to control the water level when the brake is at a standstill. However, adjustments to the main supply valve give a reasonably good control of the water flow rate. The best control of hydromatic braking can be obtained by use of a National water level control tank, which permits an infinitely variable level of water to be maintained inside the hydromatic brake when it is not running. A float inside the tank, attached to the foot valve, controls the tank drain-off and thus the tank water level. At maximum water level the float is naturally buoyant and will rise to allow water to discharge to the drain line. At any lower level the float will sink and close the foot valve. The loss of buoyancy at any other than maximum filling can be counteracted by an uplift force applied by an air cylinder operated lever system at the top of the tank. The uplift force is proportional to the cylinder air pressure, which is controlled by the driller by means of a WABCO H-4 Controlair valve located in the Auxiliary Air Control Cabinet. Thus, the tank water filling level can be varied from maximum filling at zero air pressure, all the way to empty at maximum air pressure. Since a hydromatic brake uses the water as a cooling medium as well as a working medium it is essential that an adequate volume of cool water be supplied to the level tank. As a general guide, it is suggested that a water supply of at least 20 gpm be available for each 100,000 lbs. of drill string weight to be handled with a hydromatic brake equipped with the National Water Level Control. If the temperature of the cool water supply exceeds 80º F the rate of flow should be increased by a factor of 100/(180-T1) where T1 is the water supply temperature. The discharge temperature of water from the brake should not be allowed to exceed 180º F so as not to cause steaming and loss of braking. If a water level tank is not used, a water supply 2 to 3 times as great may be required.

EPL-1439 03 50

In any event, the minimum water pressure at the inlets to the hydromatic brake should bot be less than 3 to 5 psi for maximum brake capacity, and should never exceed 15 psi. Electric brakes require water for cooling purposes only. The direct connected water supply should be capable of delivering enough water to cool the brake during its heaviest load cycle. The maximum flow requirement will vary with the size of the brake and the load to be handled. Inlet temperature should not exceed 100º F and discharge temperature should not exceed 165º F. Please refer to tabulation below of water requirements for auxiliary brakes on National drawworks. For detailed information regarding water circulation rates together with maintenance and repair instruction manuals contact the nearest auxiliary brake representative. 4.16

Adjustment – Main Drum Brakes The “K” brake mechanisms on National drawworks require little inspection; however, a common mistake is to adjust the brake bands so that the equalizer bar is down solid on one end. This prevents it from performing its function properly. Check the K-brake equalizer mechanism during rigging-up periods, and occasionally, during operation to be sure the equalizer bar is free to equalize.

EPL-1439 03 51

All of the link connections and shaft bearings are grease lubricated from two central lubrication terminals located inside the brake adjustment access door. Adjustment of the brakes can be accomplished quickly and easily. Brake adjusting wrenches for each band are held in place on the adjusting nuts by lugs on the equalizer beam for immediate use. The following illustration shows the brake adjusting eyebolt connection to the equalizer beam. The spherical shoulder on the adjusting nut is held against a spherical seat on the equalizer beam by a coil spring. (Ref. Fig 1). The spherical seat connection allows the eyebolt to align with the brake band pull as the brake lining wears and as the equalizer beam actuates. This arrangement prevents application of bending stresses to the adjusting eyebolt. The spring keeps the spherical surfaces in contact to eliminate slack and prevent impact loads when the brake is applied. Correct brake adjustment procedure is as follows: (ref. Fig 2). 1. Loosen eye-bolt lock nuts “C” and “D” with wrench “E” and adjust eyebolts to set drawworks brake lever at an angle of 35 degrees, approximately, with the floor when the brake is applied. This will place the brake lever hand pad approximately 32” above the floor level. 2. Be sure eyebolt adjustments are made so that the equalizer beam remains level when brakes are applied. There should be equal clearance (approximately ¼”) between the bottom of the equalizer beam and the brake shaft bracket at each end of the beam “A” and “B”. 3. Be sure the eyebolts are not bent, and after adjustment, retighten the eyebolt lock nuts “C” and “D”. 4. Check the position of the support roller assembly at the rear of each brake band. The roller should be set to ¼” maximum clearance with the band, with brakes “on”. This should prevent the brake lining from dragging on the rims at the top and front when brakes are released. Dragging can cause unnecessary heating and, possibly, brake lever kickback. 5. Check brake bands for roundness and uneven lining clearance when brakes are released. If bands are bent to an unsymmetrical curvature or have flattened areas, which cause dragging, they can be reshaped by a beating treatment with a heavy lead hammer. 6. Check nuts on brake lining bolts to be sure they are tight. 7. Lubricate brake mechanism at regular periods. Use oil for brake band rollers and eyebolt hinge pins.

8. Do not allow band wear to cause very low operating positions of the brake lever. Keep bands adjusted so the lever hand pad is approximately 32” above the floor. Very low lever position will give a spring-like or spongy feel. Also, extreme low positions may allow the brake mechanism to come against its end stops. Further, with new brake lining, low lever positions may allow the heads of the eyebolts to drag on the brake rims.

Drum Brake Rims Periodic inspection of drum brake rims is necessary to determine indications of uneven or excessive wear. In general, brake rim failures other than regular wear are caused by brake linings being to soft or too hard. Soft woven lining usually causes deep circumferential grooving. Very hard brake blocks cause the rims first to turn blue in spots and then crack. Frequent inspection of the brake rims and a complete change of lining might save a costly brake rim change. Two practiced methods for determining the amount of ear are: 1. The circumference of the worn rim may be measured with a steel tape. In using this method, care should be taken to wrap the tape around the rim at the point of maximum wear. 2. A gauge made of wood or metal may be laid across the rim from flange to flange and the amount of wear determined by measuring. Occasionally brake rim failure occurs when the driller neglects to turn on the brake rim cooling water before using the brakes. This can cause rim cracking if excessive heat is generated. If water is introduced after the rims become hot, steam may be generated causing water jacket damage and/or brake rim cracking due to thermal shock. When replacing lining, the rims should be checked and if there is evidence of scoring they should be turned or ground smooth. If brake rims are replaced, they should be checked for concentric mounting. When the new rims are installed, rotate the drum assembly on its main bearings. The run out of the rims on the outside surface should be limited to .015” as shown by a dial indicator. Allowable wear of National Drawworks Brake Rims

Coring Reel Brakes The loads on coring reel brakes are usually light enough that the heat developed can be dissipated to the surrounding air without causing excessive temperature rise in the brake elements. The brake rims are not water cooled. Air cooling has proved satisfactory under all normal operating conditions.

4.20

Brake Bands and Lining Each lining block on the main drum is secured with six bolts. Each lining block on the coring reel brake band is secured with four bolts, which engage with dovetail keepers. The lining bolts will loosen as the lining seats itself. They should be checked after putting new lining into service and retightened as required. Penning the end of the bolts will keep the nuts from coming off but it will not guarantee that the bolts will stay tight. They should be checked regularly. These bolts are made of brass and care should be taken not to break them by over-torquing. The lining blocks are curved to the proper radius in manufacture, but in storage this radius may change slightly. Heat and pressure in service will eventually seat the lining against the band. Good practice prescribes a breaking-in period before handling heavy loads at high speeds. Under load, the lining is kept in place on the band primarily by friction with the band. Therefore, the contact area between the lining and band should be free from oil, grease, mud, or soft paint so the block retainer bolts won’t be sheared off as a result of reduced friction. The inside of the band should not have over one coat of protective paint. In fact, no paint at all is preferable. When replacing brake lining blocks the bands should be inspected for damage caused by corrosion, loose blocks, and rough handling. The band curvature should be a relatively true radius and free from kinks. New lining may never seat properly against a kinked band. The band should be checked for accuracy of curvature, straightened if necessary and handled carefully. The clevis eyes should be kept tied together when the bands are not on the drawworks.

The repetitive application of the main brake on a drawworks subjects the dead end (eyebolts end) of the band to a stress – no stress condition. The magnitude of this stress range can lead to eventual metal fatigue. Therefore, whenever the bands are removed for relining, they should be magnafluxed to guard against fatigue cracks in the band and clevis on the dead end. The complete band should be replaced if there is any question at all about its quality. WEAR CHART FOR BRAKE LININGS

Catheads

Document number Revision Page

EPL-1439 03 56

General – National Type “A” Catheads are furnished on the 1625 series Drawworks while the Type “B-1” Catheads are provided on the 55, 80, 110, and 1320 Series Drawworks. All National catheads use air pressure applied behind a flexible diaphragm to supply the actuating force to a piston through a thrust bearing, tong line drum, and against a driving friction surface of the spool which is keyed to the catshaft. The pull on the tong line will be proportional to the applied air pressure. When the air pressure is released, return springs force the piston and diaphragm back, and a return ring pulls the drum away from the driving friction surface. The tong line drum rides on a sleeve, which is part of a stationary housing. When the cathead is disengaged, there is not tendency for the drum to creep or drag because it has no contact with rotating shaft elements. There is no intermediate mechanical linkage requiring periodic adjustment. The diaphragm automatically compensates for lining wear. The Type “A” and “B-1” breakout catheads have three clutch friction surfaces while the make-up catheads have one friction surface. Therefore the breakout units have nearly three times the torque potential of the Make-up. National catheads are equipped with a rope safety guide to separate the first two coils of soft line and keep them from overlapping when the line is around the spool. The working area of the spool is flame hardened to minimize wear. Catheading operations should not be carried on without the line passing through the guide. The guide should be inspected frequently for damage and to insure that it is in proper orientation. To assist the driller maintain a sensitive control in low piston pressure ranges (low torque ranges), where most spinning and make-up operations are performed, carefully designed control levers and air valve operating cams are featured on all National drawworks. The control levers travel in a notched slot in the control console cover. The cam is designed to give the greatest amount of lever movement in the lower pressure range. When the cathead control lever is moved from “off” to the intermediate stop notch in the lever slot the cam turns through 50 degrees and the valve delivers 0-40 psi air pressure to the cathead. In the remaining 25 degrees of the slot, 40 to 110 psi is supplied. By proper manipulation of the lever, any line pull from zero to the maximum can be applied to the tongs. All parts of the Type “A” Breakout and Make-up Catheads are interchangeable except the drum, clutch elements, rope spool, rope guard, and bracket. The same applies for the Type “B-1” Catheads. The wearing parts of the catheads are the piston diaphragm, clutch linings, bearings, and return springs. www.nov.com

Each Type “A” Cathead has four grease fittings while the Type “B-1” Catheads have one grease fitting each to lubricate all bearings and bushings. At rig start up, the catheads should be greased liberally but not excessively, as the overflow may migrate to the clutch friction lining, which can cause contamination and impair cathead operation. After each trip the catheads should be given two or three shots from a hand grease gun. Caution: Excessive greasing or the use of grease of too-firm consistency may resist the return of the tong line drum to a neutral position after clutch engagement. Always allow the catshaft to rotate a few minutes after greasing before actuating the catheads. Type “A” Catheads – (Type 1625-DE/M Drawworks only) Each cathead has four grease fittings; one in Item (5), one in Item (38), one each in (17) and (25) which are accessible through a window in the front of Item (23). Ref. Fig. 1, page 45. Catheads with new clutch linings should have the following piston movement when air pressure is applied: Type A Breakout: 3/16” Type A Make-up: 1/16” When the piston movement becomes 3/8” and 1/8” respectively on breakout and make-up catheads the clutch linings should be replaced. The following instructions cover disassembly of the breakout cathead. Disassembly of the make-up cathead should follow the same procedure except for Items 3, 7, 10, 11, 12 and 41, illustrated in Fig. 1, page 45, as the make-up cathead has only one friction surface. Disassembly: 1. Remove cap screws (1) and (3) and rope guard (2). 2. Back-off retainer bolt (4) two or three turns and apply air to the cathead. Tap the spool (6) until it breaks loose from the tapered shaft extension. Turn off the air, being sure the piston is vented; remove the retainer bolt, end plate (5) and spool. 3. Remove cap screws (8) and clutch plate retainer (9). Clutch plates (10) and (11) may now be removed for repair or replacement. 4. Check clutch plate springs (7) and (12) and replace if broken or weak. 5. Remove cap screws (13), bearing retainer (14) and shim set (16). Check oil seal (15) and replace if worn or deteriorated.

6. Withdraw drum assembly (17) from the piston to inspect bearings (18) and (19). Retainer (20) must be removed before the cup of bearing (19) can be pulled from the drum. Friction linings (21) should be replaced if worn close to the rivet heads. New linings are ¼” thick. 7. Remove housing retaining nuts (22), housing (23), and piston assembly (25). Check piston return springs (24) and replace if broken or weak. Check bronze bushings (26) and (30) for wear and replace if over .020” loose on sleeve. 8. Remove slotted nut (27) and diaphragm retainer (28); diaphragm (29) may now be removed for replacement. 9. If the main body (38) exhibits excessive side play (over .008”) at the same end of the sleeve, the shaft bearings should be checked. This requires complete removal of the catshaft assembly from the drawworks, since bearing (39) and the spherical radiused trunnion of the sleeve comprise the shaft support in the drawworks frame. 10. After removal of the catshaft assembly from the drawworks, remove cap screws (31). The cathead sleeve (38) can now be pulled from the shaft. (Note: If the shaft assembly is removed from the drawworks, the cathead assembly can be removed from the shaft as a unite after completing instruction (2) above, and after removal of cap screws (31). 11. Pilot bearing (36) and main bearing (39) can be pulled after removing lock nut (33). 12. Refer to Illustrated parts List of drawworks for specific part numbers of required replacement parts. Always give drawworks serial number when ordering parts. 13. Refer to specific drawworks section of this manual for listing of bearing fits in the cathead assemblies. Reassembly: Type “A” catheads have two sets of adjustment shims. Shim set (16), Fig. 1, page 45, should be selected to establish .003 to .005” end play of the drum (17) after reassembly. These shims are available in thickness of .005”, .007”, and .020”. Shim set (40) Fig. 1, establishes the location of main bearing (39) on the shaft and thus the distance of the face of clutch lining (21) from the friction surface of the spool (6). This distance should be 1/16” on make-up catheads and 3/16” plus the combined thickness of clutch plates 910) and (11) on breakout catheads.

On breakout catheads, the clutch plate retainer (41) allows 1/8” total released running clearance for a new friction disc (10), and proper selection of shim set (40) thickness establishes the additional 1/16” released running clearance between new friction lining (21) and plate (11). Shims (40) are available in thickness of 1/64, 1/32, and 1/16”. (Note: Normally, shim set (40) will need no adjustment, if cathead repairs consist only of replacing friction linings, diaphragms, or roller bearings). Because of variations resulting from accumulation of manufacturing tolerances the shim set (40) should be re-established whenever a complete new cathead is installed or whenever replacing the spool (6), drum (17), or sleeve (38). A convenient method for determining the required thickness of shim set (4) is as follows: 1. Install spool (6) on shaft and measure dimension “A” from friction surface to face of bearing spacer (42) as illustrated in Fig 2, page 45. 2. With sleeve of cathead completely assembled, including main bearing (39) (and plates (10) and (11) on breakout catheads), assemble all parts that mount on sleeve (38), including items (41), (12), (11), (10), (9), but less items (2) and (32). Install cup and outer cone assembly of main bearing (39). Set this assembly on a surface plate as shown in Fig. 3, page 45. With springs (12) forcing clutch plate (10) against retainer (9), measure dimension “B” from surface plate to top of plate (10). 3. The required thickness of shim set (4) is the difference between dimension A and B minus 1/16”. (i.e., shim thickness = A – (B + 1/16). 4. Reassemble cathead on the catshaft in proper parts sequence, tighten bolt (4) and check forward movement of drum (17) when air pressure is applied. Nominal piston and drum assembly movement is to be 1/16” for breakout cathead with new clutch linings. A small negative tolerance is allowable for this movement if no clutch drag is evident.

EPL-1439 03 61

Each cathead has only one grease fitting; Ref. Fig. 4 (Item 55), page 47. Catheads with new clutch linings should have the following piston movement when air pressure is applied: Type “B-1” Breakout: Type “B-1” Make-up:

3/16” 1/16”

When the piston movement becomes 3/8” and 1/8” respectively on breakout and make-up catheads the clutch linings should be replaced. The following instructions cover disassembly of the breakout cathead. (Ref. Fig. 4, page 47). Disassembly of the make-up cathead should follow the same procedure except for steps 2 and 4 below as the make-up cathead has only one friction surface. Disassembly: To replace friction lining: 1. 2. 3.

4.

Remove rope hanger and guards (10, 11, and 35). Remove the three friction plate retainers (45). Loosen retaining bolt (34) a turn or two and apply air to the cathead to force the spool (3) loose. It may be necessary to tap the spool with a hammer to break the taper fit. Turn off the air, making sure the piston is vented; removed retainer bolt, and end plate (42). The spool can then be removed and the friction lining replaced. Remove friction plate retainer (36) to gain access to the inner plates (12) carried on the drum (1). Examine centering springs (52) and replace if broken or damaged. When reassembling, make sure capscrews (67 and 69) are securely tightened.

To replace air diaphragm or bearings: 5.

6. 7.

Remove spool as instructed above. The remaining cathead assembly including all bearings can now be moved forward and off the shaft. If only the diaphragm is to be inspected or replaced the cathead needs to be moved forward only enough to gain access to diaphragm retainer screws (16 and 62). Remove spring retainer (7) and slide the drum and piston (26) off the sleeve as a unit. The diaphragm (24) and diaphragm retainer (5) can now be removed. Check ring to element washer (17) for deterioration. Check end play between drum and drum return ring. (2). On new catheads this is set to approximately .010”. If clearance checks over .015” remove .005” shim (32).

Check fit of bushed drum assembly A(1) on sleeve. When new this runs from .007” to .013” loose. If worn fit is over .020” loose bushing replacement should be considered. Check anti-friction bearings (8) for damage or excessive war including inspection of bore of sleeve. Replace oil seal (48) if it shows evidence of leakage.

Refer to drawworks illustrated parts list for part numbers of replacement items required. When ordering spare parts, always give model and serial number of drawworks. Reassembly: 1. 2.

3. 4.

Use original shim set (19, 20, 21, 22) and reinstalls cathead on the shaft. Install spool firmly but do not tighten retainer bolt (34). Check clearance between friction lining (30) and adjacent face. This should be 1/16” minimum, and can be observed through slots in the rim of the spool. If clearance correction is necessary, remove spool and main body assembly as a unit. Then add or remove shims to obtain proper clearance. Reassemble cathead on shaft and tighten retainer bolt. Reconnect air supply line and grease cathead. Be sure anchor bracket (9) is not jammed and anchor spring (43) is installed. Apply air to the cathead. Upon released of air pressure, the quick release valve in the supply line should pop-off and the drum should retract instantly. There should be no dragging action in the clutch elements when the shaft is running.

Parts Fit General – Economic features enter into the normal overhaul job; no one wants to spend money needlessly; however, at the time the equipment is in the shop for repairs new parts may be installed at far less expense than when the equipment is in service. For example, it has become customary in our own shops, when making a major overhaul, to replace many roller bearings throughout the drawworks. Some of the bearings replaced may still have some life left in them, but should the repair shop fail to replace a bearing at the tie of overhaul, and should this old bearing fail within the first few months of new service, the resultant costs from down time and emergency repairs will amount to many times the cost of replacement at regular overhaul time. When replacing parts on a shaft assembly, be sure that the new part fits within the tolerance shown. For assembly or removal of parts which fit from .000” to .004” tight, heat to approximately 400º F; for parts which fit from .005” to .010” tight, heat to approximately 650º F. Shafts – Wherever possible, all shafting should be checked by magnaflux or other means to detect any cracks. Cracks are most likely to appear in the bottom of keyways. A cracked shaft should be discarded and replaced, as a crack is a danger signal for a bad failure. Shafts should also be checked for straightness. This is accomplished by supporting it by any anti-friction means placed at the position of the main bearings, and turning it. Straightness is then checked by means of a dial indicator placed at the extreme ends of the shaft. The total reading of the dial indicator should not exceed .010”. If a shaft shows a greater run out then .010” a replacement should be considered. The lack of straightness in drawworks shafting causes vibration, whipping of chains and a generally poor runner rig. Bearings – Roller bearings should always be discarded if they show pitting, rust or corrosion, chipping or spalling off of small particles, excessive internal looseness which indicates extreme wear, or cracks in rollers or races. In most cases it will be necessary to heat the bearing inner race, in order to remove it from the shaft. It will be necessary to heat the inner race and cool the shaft for reassembly. To pull the bearing and/or the inner race, place a “U” puller behind bearing or inner race. Arrange balance of the pulling mechanism and tighten sufficiently to remove all slack. Apply heat evenly to the bearing or inner race, while at the same time increasing tension on the pulling mechanism. DO NOT OVERHEAT.

EPL-1439 03 66

Fits of the outer races to the bearing housing range from .005” tight to .004” loose. If the outer race is tight fit it will be necessary to heat the housing in order to remove it. The bearing must be cool before it can be reassembled. When outer race is a tight fit, arrange the puller mechanism to apply pressure toward the open end of the housing. Apply heat to the housing and increase pressure on the puller mechanism at the same time. DO NOT OVERHEAT. Spacers – Spacers used between bearings to maintain centerlines of bearings, or between bearings and other parts, are usually .002” to .006” loose. Spacers, which are used to hold a bearing in position, which is not adjacent to anther part securely fixed to the shaft, are usually .001” to .003” tight. To remove a spacer, which is shrunk on a shaft, proceed in accordance with instructions for removing a bearing. To replace, heat the spacer, and make sure the shaft is cool, and proceed the same as for bearing replacement. Sprockets and Clutch Hubs – The teeth of almost all sprockets are surface hardened. This hardening is effective to a depth of approximately 1/8”. After several years usage the chain may wear into the sprocket teeth. When the sprocket teeth become worn to a depth near 1/8”, the rate of war will accelerate. The amount of war may be ascertained by visual inspection. If inspection shows the amount of wear to be near 1/8”, the sprocket should be replaced at the time of overhaul. Four methods are used for mounting clutch hubs, bearing inner races and sprockets on shaft assemblies. (1) Press fit without key. (2) Press fit with key. (3) Shrink fit without key. (4) Tapered shaft with key.

When removing and replacing parts mounted according to arrangement (1) above, refer to instructions for removing bearings. Sprockets mounted according to arrangement (2) above may have a straight key, which has a tapped hole in the end of it. Screw puller in this tapped hole and remove the key. The sprocket may then be removed, usually with applying heat. If a tapped hole is not provided in the key, it will be necessary to pull the sprocket without first removing the key. Insert puller studs through openings between sprocket spokes 180 degrees apart. Place steel plates and nuts on stud ends extending through the openings. Arrange balance of pulling mechanism and tighten only enough to remove any slack. Apply heat evenly and as near to the hub as possible while increasing tension with the puller at the same time. DO NOT OVERHEAT. In some cases the hubs will have two tapped holes in the end so that puller studs may be screwed in. In other cases where neither spokes nor tapped holes are available for utilization of puller studs it will be necessary to use a “strongback” or “U” plate behind the sprocket and secure the puller studs to it. Proceed to remove the sprocket as described in the foregoing paragraph. To replace the sprocket, first be sure that the shaft is cool. Heat the sprocket to approximately 400º F. Be sure that the keyways in the shaft and sprocket are aligned before the sprocket tightens on the shaft. Insert key after sprocket has been installed. Caution – Express heat at the hub and attempting to pull the sprocket with a chain attached to the outer rim, powered by a jack on the end of the shaft will bend the sprocket. Sprockets with shrink fits are very difficult to remove. This should only be attempted in a shop where a hydraulic press is available. If the sprocket is being removed for salvaging and installing on a new shaft, cut the shaft near the sprocket and machine part of the metal from the shaft under the sprocket. Heat the sprocket and press out “Dutchman.” If purpose of removal is to replace the sprocket with a new one it is advisable to machine or torch cut the old sprocket to remove it. Let the shaft cool, heat the new sprocket to 650º F and assemble on the shaft. Important – When a shaft assembly is disassembled for any reason, be sure that passages for admission of air or grease are thoroughly cleaned. Hub and Shaft Fits – The temperature required to expand a hub enough to be assembled easily over an interference fit can be determined by the following equation: T = E/(.0000061 x B) + Tr Where T = Heated Temperature, ºF E = Expansion of Bore Diameter Required B = Bore Diameter (inches) Tr = Room Temperature, ºF .0000061 = Approximate Coefficient of Expansion of steel per degree Fahrenheit per inch of length (or diameter) www.nov.com

For example, if we have a 8.500” diameter bore hub which has an .008” interference fit whith the shaft and we wish to have .010” clearance while assembling the hub over the shaft – the total bore expansion needed will be .018”, therefore, E = .018 B = 8.5 let Tr = 70º F then T = .018/(.0000061 x 8.5) + 70 = 420º F Caution: Hardened parts such as bearing races should not be heated to over 400-450º F, since their hardness might be affected. Heat should be applied carefully and evenly to prevent distortion. The general rule for the average interference used in cylindrical fits is as follows: Press fit: - .0005 x shaft diameter Shrink fit: - .001 x shaft diameter The actual fit will have a plus or minus tolerance depending on the shaft and bore tolerances used in manufacture. Overhung sprockets, clutch hubs, etc., are often made with tapered shaft fits for convenience of assembly and disassembly. The tapers used on National drawworks are normally made to 1.2500 inches on diameter per foot of length of engagement. In many cased the hub must be shimmed against an adjacent bearing spacer. Care must be taken to be certain that the shims do not interfere with drawing the hub up tight on the taper. A recommended method of assembling hubs requiring shimming is to assemble the hub firmly on the shaft without shims and without heat. Measure the shim gap behind the hub. The thickness of the shim pack required will be this measurement minus the draw allowance to be provided for tightening the hub up on the shaft. For each .001” of diametral interference on a 1.250 per ft. taper the hub will advance approximately .010”. Therefore, for example, if a .003” interference is desired in the taper fit, the shim gap must allow for a .030” advance o the hub on the shaft. The hub may be lightly heated to facilitate the draw.

PRESERVATION OF MACHINERY

5.1

Outdoor Storage of Rigs

EPL-1439 03 69

Stacking – Enough beams should be provided to give normal support to the rig and be high enough to avoid having accumulated or run off water reach the equipment. A drained location is preferable so that water will not remain under the rig and cause abnormal dampness. Cleaning – Mud, adhering dirt, and other foreign matter of a type that will hold moisture should be removed. Contaminated sumps should be drained. If cleaning is done with steam or with gasoline, car should be taken to avoid washing lubricating oil or grease from unpainted surfaces unless it is to be replaced or a preservative compound applied. If, in cleaning, the lubricant is removed from close fittings elements, they should be rotated after new lubricant or a preservative has been applied so that it will work into the fits. In case it is necessary to run contaminated liquid through a circulation pump, in the draining of an oil sump, clean oil should be run through the pump afterward. Minimizing Condensation – if an air tight package could be made around the rig, bags of desiccant could be hung in appropriate locations to reduce the humidity of the inside air to a point where there would be no interior condensation and therefore no rusting. This appears to be impractical for the rig as a whole, but it could be approached in transmission cased which are sealed except for a singe vent, if the bags of desiccant were replaced periodically. In the remaining discussion it will be assumed that a desiccant is not used. Condensation occurs when warmed air which has absorbed moisture becomes cooled and loses moisture. Within a transmission case, condensation occurs in the evening when the still warm inside air circulates against the cooling walls of the structure, and in the morning when the warming inside air circulates against the still cool machinery. Transmission cases and the like should be sealed except for the bottom drain hole. This opening will allow accumulated condensate (or any leakage) to escape and the cooler air drawn in at night will tend to have lower moisture content. Theses two actions will tend to reduce the condensation in the case. If the case does not drain well, a little lubricating oil placed on the bottom will float on any water that does not run off and prevent its being reabsorbed by the air in the case.

Protective Oil and Grease – The run-in oil used at the factory contains a rust preventive additive. It is recommended that the use of such an oil be continued in service. In any case, unless it is necessary because of contamination, the oil should not be removed from between close fitting machine elements. When applying a preservative, it may be necessary to wipe the surface oil away so that the preservative will adhere, but this should not effect the oil in the fits. The grease used at the factory was of the all-purpose type, resistant to heat, cold, water wash, and corrosion, and it was compatible with other greases. If such a grease was used while the rig was in service, it will provide excellent storage protection. In any case, clean grease need not be removed from the bearings. The more grease there is in a bearing, the smaller the volume of air will be, and therefore the least chance for condensation of moisture. By hand packing the exposed areas of bearings with an all-purpose grease, protection will be provided which will neither soften and run with heat nor become rigid with cold, and will not wash away. If a bearing is particularly exposed, waterproof tape may be useful in protecting it. The surface upon which the tape is to stick should be made clean and the tape applied in a manner which assures that it will shed rather than collect water. Applying Preservatives – Detail information on the various protective materials referred to will be found at the end of this section. Grease type rust preventive is recommended for general use where its greasiness is not objectionable. It is usually brushed on and provides a relatively thick coating which retains its effectiveness. It can be worked into fits and is compatible with lubricating oil. It can be thinned or removed with gasoline or kerosene. The grease type rust preventive is particularly valuable when worked into the pivot bearings of chain, control linkages, and the like. All-purpose lubricating grease is also useful in this way. Even when it is desirable to use a film type preventive on the external surfaces of machine elements, the grease type is best on close or sliding fits, in small holes, and on threads. Dry film type rust preventive is recommended on the external surfaces of shafts, drums, and other machine elements where the grease type would be a nuisance during handling, when rubbed against, or upon return to service. It also makes a good coating on unpainted structural surfaces such as the interiors of guards or oil chambers. It is compatible with lubricating oil. It can be brushed or sprayed on and can be thinned or removed with gasoline. While the dry film type preventive does not have the self-healing property of the softer grease type, it has good scuff resistance. Both types provide protection through chemical affinity for metal, as well as the physical barrier. Sealing Opening – If a rig is not be covered by a weather tight tarpaulin, access covers and door and joints in the structure which do not close tightly enough to prevent water from blowing in should be caulked or otherwise packed with greased or white leaded soft rope, or other packing material, or sealed with two or three inch wide adhesive waterproof tape. Waterproof tape is convenient to use and effective. It should be applied over a cleaned surface. When it is used, some touch-up painting may have to be done at the time of the return of the rig to service as the tape tends to lift the top paint coat when removed.

Small openings can be covered by tape alone, or by tape and plastic sheet, unsupported. Large openings, such as those above the cable and sand line drums and at guard junctures, should be boarded up and covered with plastic or other waterproof material to make a weather tight seal. The wood should be wired or otherwise held in place securely so that it will not move from position when it shrinks with drying. Waterproof tape, two or three inches wide, is convenient and effective for use in sealing between the plastic and the structure. If roofing nails or staples are used to hold the plastic close to the boarding, a covering piece of tape will seal and strengthen at that point. An equivalent seal, to that of the plastic sheet with adhesive waterproof tape, could be provided by laying plastic screen over the seams, covers, doors, openings, and spraying on a cocooning compound which would adhere to the structure and bridge the screen openings to from a continuous material. The tape and sheet material appear to be more convenient for use in the field. Touch-up Painting – It is best to do major touch-up painting before a rig is stored. Loose paint and rust should be wire brushed away, the surface cleaned with white gasoline, or other non-oily cleaner and primer applied again to a dry surface. Do not paint when the atmosphere or the surface is damp. If attachments have been added or modifications made to the rig in the field, to assure a lasting paint job; blunt sharp corners, edges, and projections; top scabs and laps; trim ragged torch cuts or broken tack welds; scrape or wire brush away weld slag and spatter, mill scale, or rust; and as above, make sure that the surface is clean and dry. Touch-up painting can be done conveniently with a brush or with an electrical spray gun. Hooding Control Cabinets – If a rig is not to be covered by a weather tight tarpaulin, it is desirable to place a hood of plastic or other waterproof material over the control cabinets or similar structures having openings around handles, or the like, which are difficult to seal. Before hooding is applied, lubricating or rust preventive oil should be worked into the pivots and rollers to prevent corrosion access. A pressurized spray can of rust preventive is handy for protecting the valves. The pivot points of the heavy mechanical control linkages located below the floor should be protected by grease type rust preventive or all purpose lubricating grease, worked into the fits. The hooding should be tied or taped snugly in place. It should cover all openings above the floor.

Covering with a Tarpaulin – If a plastic tarpaulin is used to cover the rig it should be no less than six-thousandths of an inch in thickness. Black plastic stands the sunlight better than clear. A tarpaulin material should be used which will not become wet through, as this would tend to cause accelerated corrosion wherever it touched. Before applying the tarpaulin, all points, ridges, or other abrupt contour changes, with which the covering will come into contact, should be rounded by padding with folding cloth or paper, tied or taped in place. Large openings, such as those above the cable and sand line drums and at guard junctures, should be boarded up sufficiently to give support to the tarpaulin. The wood should be wired or otherwise held in place securely so that it will not move from position when it shrinks with drying. If it is desirable to hold in the tarpaulin at a point where it is supported by wood framing, a strip of wood may be placed over the tarpaulin and nails driven through into the framing. Or, the tarpaulin may be reinforced with waterproof tape and roofing nails or staples driven through into the wood. The tarpaulin may be held at other desirable points by running a strip of wood though door handles, or by wiring the wood in place elsewhere, and fastening to it as above. Where the supporting wood is not flush with the structure surface, the ends should be padded. The tarpaulin should be carefully draped so that there will be no folds or depressions which will catch water, especially if freezing may occur, as such points of weight would destroy a tarpaulin in the wind. Plenty of light rope or cord should be used to keep the tarpaulin draped as desired, provide support, and prevent billowing and fluttering. A strong attachment point can be made by reinforcing across the direction of the pull with two-inch wide waterproof tape, six inches long, stitching a four-inch nail through the tape and tarpaulin for times and attaching the line to the center of the nail. An additional piece of tape, laid over the joint, makes it secure. Excess material can be held in controlled folds by stitching longitudinally with a nail at tape reinforced pints, though the multiple thicknesses, again taking care not to form a pocket which will collect water. Tape may also be used across the line to keep it in place at points where it would tend to slip form position as it slackens in the wind. 5.2

Storage Of Parts And Subassemblies Absorbent Materials a Hazard – Parts shipped in closed vehicles, or given weather tight packaging, may be received with cushioning material around them, such as shredded wood or paper, burlap sacks, or cotton or paper bags, which will absorb and hold moisture if exposed to rain or condensation. Such material should not be used in storing machinery parts if there is any likelihood of dampness, as there would tend to be accelerated corrosion wherever the damp material touched the part.

Support Points Critical – The areas where a part contacts the material it rests upon are the most likely places for corrosion to occur because of collection of moisture there. If possible, parts with finely finished surfaces should be positioned so that these surfaces will be in the clear. For example: polished bearing rollers and pump rods should be stored on end. If a finely finished piece must be stored horizontally, either in a box or on a shelf, blocks should be placed under it to provide clearance for drainage. If wood blocks are used, a nonabsorbent material, such as a piece of plastic or waterproof tape, should be placed over the contacting surface of the wood to prevent its acting as a wick to draw away the preservative or bring in acid-laden moisture, as the wood becomes alternately dry or damp. Care should be taken that the plastic or tape is positioned so that it sheds rather than collects moisture. Damage Prevention – When it is desirable to protect external threads of smooth surfaces against the possibility of physical damage, care must be taken or the effort to provide protection against being struck which may result in a condition which traps moisture and invites corrosion. In using metal or molded screw type thread protectors, ample grease type rust preventive, or suitable thread lubricant, should be used so that it will completely fill the space between the eternal and internal threads and squeeze out at the ends to form a barrier to moisture. If the thread protector comes up against or near a shoulder, particular care should be taken to provide enough preservative to completely fill the space between and squeeze out to form a barrier. Waterproof tape or plastic sheet can be used to protect external threads if applied over an ample layer of grease type rust preventive, or thread lubricant. Here again, the preservative should squeeze out at the ends of the wrap to provide a barrier. Care must be taken at the ends of the wrap to avoid having it form a catch basin for moisture. The tape will stay in place by sticking to itself along the overlap. Tape can also be used to hold in place and seal plastic sheet used for damage prevention. Absorbent materials should not be used in this way. Heavy weight aluminum foil should make a good protective wrap over preservatives. It can be sealed and held in place with waterproof tape, using care so that it will not trap moisture. Waxed paper will provide an economical indoor covering if used over an ample coating of film type or grease type rust preventive. It should not be used over bare metal, or even that covered with oil, because it may contain residual acid from its processing which would be apt to have an effect unless there is a heavy preservative barrier. Ordinary tape may be used in place of waterproof tape in indoor applications, except in cases of unusual dampness. Plain kraft paper should not be used as a wrapping as it is both absorbent and apt to contain residual acid. Tape should not be used on finished bare metal. Even if the adhesive is known to be noncorrosive, there is a tendency for corrosion to occur along the step of the overlap. This can be avoided by first coating the surface with dry film, grease, or oil type rust preventive.

Applying Preservatives – The recommendations of the section so titled under Outdoor Storage of Rigs also apply here. Subassemblies should be given particular attention, especially if the metal is heavy enough to change temperature slowly and thus accent the tendency for condensation to occur. Oil type rust preventive may be conveniently sprayed into recesses of interiors with an electrical spray gun or from a pressurized spray can. Rust Preventive Wrappings and Envelops – The factory has used volatile corrosion inhibitor paper for about 15 years. When old stock is unwrapped it is always found to be perfectly protected. Up to the present, that used has been creped, double thickness paper with an asphaltic barrier between sheets. One side is coated with an adhering white powder called VPI, vapor phase inhibitor, which gives off the vapor that forms a chemical barrier at the contact between the metal and moisture to prevent rusting. When condensation has occurred during storage, there may be found a fine powder at condensation points where the vapor has gone into solution in the moisture, to provide chemical protection, and later has been precipitated upon the surface when the moisture evaporated. The white powder easily wipes away with an oily cloth and leaves no residue. A recently developed inhibitor paper, that is gaining acceptance by bearing manufacturers, has the vapor producing constituent impregnated in the paper and a wax-like barrier coating on the surface that is to be outside. Also recently developed is a transparent, very tear resistant, heat sealable plastic sheet which has a vapor producing coating on one side. The can be procured in the form of bags or can be made into bags or other forms as needed through the use of an electric heat sealing iron, or through the use of adhesive tape. An advantage of the transparent type is that the item and its identification marking can be seen clearly through it. But, if desirable, the part number can be written on the plastic with a pen. While some VPI vapors are effective through light oil, none can be dependable through heavy oil or grease, so most items are packaged dry in VPI wrapping. For this reason, the item should be kept wrapped until ready for use, be re-wrapped if opened and not used soon, or coated with oil or grease type rust preventive after opening. Vapor protective paper is of special value in protecting large bearings, such as swivel thrust bearings, which are heavy enough to be subject to fretting if the races and rollers can move upon each other during shipment, due to vibration. This fretting is eliminated by placing VPI paper between the rollers and races and wrapping the assembly tightly together.

RECOMMENDED SPARES The following is a suggested list of recommended spare parts for the first year of normal rig operation covering all National drawworks. Column (1) lists recommended spare parts which should be carried in stock at all times for each rig. Column (2) lists minimum amount of spares for each rig that may possibly be required after one year of normal rig operation. The recommended spares shown here do not attempt to cover the eventuality of unexpected breakdown of major parts. The customer should study the illustrated parts list for the drawworks and select any additional spares that the may consider practical to have in stock. A proper maintenance program and periodic inspection of the drawworks will discover incipient wear or deterioration of parts soon enough to allow time for delivery of replacement from National factory stock. For those sections covering both mechanical and electric rigs, the lists specify spare parts for either drawworks except where noted.

Controls-Operation-Electric Drawworks ( 80-Ue ) The following are the functions and operations of various controls located in the main control cabinet for the 80-UE drawworks:

Main Water Supply Pressure Gauge - Indicates pressure of main water supply to the drawworks. For detailed information regarding pressure and water flow rates, please refer to pages 38 and 39. Cascade Lubrication System Oil Pressure Gauge – Indicates discharge pressure of the cascade lubrication system pump. Working pressure varies with distributor valve setting and viscosity of the oil. The gauge should be used to indicate to the operator whether or not oil is being circulated through the cascade system. Main Air Supply Pressure Gauge – This indicates pressure of main air supply to the drawworks. Minimum pressure should be 110 psi. Drum Clutch – Indicates pressure of the air to either high or low drum clutch. Working pressure should be approximately 110 psi. Make-up, Breakout Cathead Controls – Regulates flow of air to catheads. Push lever away from operator to engage cathead friction clutch. This lever is spring loaded and will return to the OFF position when the hand is removed. The slot in which the lever travels is offset to permit application of less than full air pressure when required for certain operations. The knurled knob at the right of the slot is a safety lock for the lever. Use this lock to prevent accidental engagement of cathead and possible serious injuries to personnel. Low and High Drum Clutch Control – Regulates flow of air to both the low and high drum clutches. Move lever into the left leg of “U” shaped slot to engage the low drum clutch and into the right leg of the “U” to engage the high drum clutch.

EPL-1439 03 103

Master Clutch and Inertia Brake Control – Regulates the flow of air to both master clutch and inertia brake. Move lever away from operator and into left leg of “U” shaped slot to engage the master clutch and away from operator and into right leg of “U” shaped slot to engage the inertia brake. Engine Throttle Control Levers – These engine throttle control levers for group 1, 2 and 3 engines remotely control actuators on the engines to accelerate or retard engine R.P.M. Push lever away from operator to accelerate engines. These controls are friction loaded and will remain in position to maintain desired operating speed. The throttle group selector valves are manifolded together and controlled by the engine throttle levers to establish various combinations of engine selections. Main Water Supply Pressure Gauge - Indicates pressure of main water supply to the drawworks. For detailed information regarding pressure and water flow rates, please refer to pages 38 and 39. Cascade Lubrication System Oil Pressure Gauge – Indicates discharge pressure of the cascade lubrication system pump. Working pressure varies with distributor valve setting and viscosity of the oil. The gauge should be used to indicate to the operator whether or not oil is being circulated through the cascade system. Main Air Supply Pressure Gauge – This indicates pressure of main air supply to the drawworks. Minimum pressure should be 110 psi. www.nov.com

EPL-1439 03 104

Drum Clutch – Indicates pressure of the air to either high or low drum clutch. Working pressure should be approximately 110 psi. Make-up, Breakout Cathead Controls – Regulates flow of air to catheads. Push lever away from operator to engage cathead friction clutch. This lever is spring loaded and will return to the OFF position when the hand is removed. The slot in which the lever travels is offset to permit application of less than full air pressure when required for certain operations. The knurled knob at the right of the slot is a safety lock for the lever. Use this lock to prevent accidental engagement of cathead and possible serious injuries to personnel. Rotary Drive Clutch – This lever engages the rotary clutch when moved away from the operator. Use the safety lock at the right side of the slot to prevent accidental engagement of rotary clutch. Low and High Drum Clutch Control – Regulates flow of air to both the low and high drum clutches. Move lever into the left leg of “U” shaped slot to engage the low drum clutch and into the right leg of the “U” to engage the high drum clutch. 9.2

Mechanical Controls Transmission selection is achieved by manually raising or lowering shifter handles located on the front of the main control cabinet. The center position of the lever slot is neutral. At least one of the levers must be in neutral before any transmission selection can be engaged. High-Reverse Transmission Shifter – Lift the lever into its upper position to shift transmission to high speed ratio. Placing the lever in its lower position shifts the transmission into reverse. The center position of the lever slot is neutral. This lever must be in the neutral position before the low-second clutch can be engaged. Low-Second Transmission Shifter – Lift the lever into its upper position to shift transmission to low speed ratio. Placing the lever in its lower position shifts the transmission into second speed ratio. The center position is neutral. This lever must be in neutral position before the high or reverse clutch can be engaged. Low Drum-Catshaft Drive Shifter – The low drum drive and catshaft is engaged by placing this lever in its lower position, and disengaged by placing it in the upper position.

1320-M/UE DRAWWORKS Controls – Operation – Mechanical Drawworks (1320-M) The following are the functions and operations of various controls located in the main control cabinet for the 1320-M drawworks:

Master Clutch and Inertia Brake Control – Regulates the flow of air to both master clutch and inertia brake. Move lever away from operator and into left leg of “U” shaped slot to engage the master clutch and away from operator and into right leg of “U” shaped slot to engage the inertia brake. Engine Throttle Control Levers – These engine throttle control levers for group 1, 2 and 3 engines remotely control actuators on the engines to accelerate or retard engine R.P.M. Push lever away from operator to accelerate engines. These controls are friction loaded and will remain in position to maintain desired operating speed. The throttle group selector valves are manifolded together and controlled by the engine throttle levers to establish various combinations of engine selections. Main Water Supply Pressure Gauge - Indicates pressure of main water supply to the drawworks. For detailed information regarding pressure and water flow rates, please refer to pages 38 and 39. Cascade Lubrication System Oil Pressure Gauge – Indicates discharge pressure of the cascade lubrication system pump. Working pressure varies with distributor valve setting and viscosity of the oil. The gauge should be used to indicate to the operator whether or not oil is being circulated through the cascade system. Main Air Supply Pressure Gauge – This indicates pressure of main air supply to the drawworks. Minimum pressure should be 110 psi. www.nov.com

EPL-1439 03 120

Drum Clutch – Indicates pressure of the air to either high or low drum clutch. Working pressure should be approximately 110 psi. Make-up, Breakout Cathead Controls – Regulates flow of air to catheads. Push lever away from operator to engage cathead friction clutch. This lever is spring loaded and will return to the OFF position when the hand is removed. The slot in which the lever travels is offset to permit application of less than full air pressure when required for certain operations. The knurled knob at the right of the slot is a safety lock for the lever. Use this lock to prevent accidental engagement of cathead and possible serious injuries to personnel. Rotary Drive Clutch and Inertia Brake – This lever engages the rotary clutch when moved away from the operator. Move lever toward operator to engage the inertia brake. The operator should pause momentarily between disengagement of the clutch and engagement of the brake. Use the safety lock at the right side of the slot to prevent accidental engagement of cathead. Low and High Drum Clutch Control – Regulates flow of air to both the low and high drum clutches. Move lever into the left leg of “U” shaped slot to engage the low drum clutch and into the right leg of the “U” to engage the high drum clutch. 10.2

Mechanical Controls Transmission selection is achieved by manually raising or lowering shifter handles located on the front of the main control cabinet. The center position of the lever slot is neutral. At least one of the levers must be in neutral before any transmission selection can be engaged. High-Reverse Transmission Shifter – Lift the lever into its upper position to shift transmission to high speed ratio. Placing the lever in its lower position shifts the transmission into reverse. The center position of the lever slot is neutral. This lever must be in the neutral position before the low-second clutch can be engaged. Low-Second Transmission Shifter – Lift the lever into its upper position to shift transmission to low speed ratio. Placing the lever in its lower position shifts the transmission into second speed ratio. The center position is neutral. This lever must be in neutral position before the high or reverse clutch can be engaged. Low Drum-Catshaft Drive Shifter – The low drum drive and catshaft is engaged by placing this lever in its upper position, and disengaged by placing it in the upper position, disengaged by placing it in the lower position.

Master Clutch and Inertia Brake Control – Regulates the flow of air to both master clutch and inertia brake. Move lever away from operator and into left leg of “U” shaped slot to engage the master clutch and away from operator and into right leg of “U” shaped slot to engage the inertia brake. Engine Throttle Control Levers – These engine throttle control levers for group 1, 2 and 3 engines remotely control actuators on the engines to accelerate or retard engine R.P.M. Push lever away from operator to accelerate engines. These controls are friction loaded and will remain in position to maintain desired operating speed. The throttle group selector valves are manifolded together and controlled by the engine throttle levers to establish various combinations of engine selections. Main Water Supply Pressure Gauge - Indicates pressure of main water supply to the drawworks. For detailed information regarding pressure and water flow rates, please refer to pages 38 and 39. Cascade Lubrication System Oil Pressure Gauge – Indicates discharge pressure of the cascade lubrication system pump. Working pressure varies with distributor valve setting and viscosity of the oil. The gauge should be used to indicate to the operator whether or not oil is being circulated through the cascade system. Main Air Supply Pressure Gauge – This indicates pressure of main air supply to the drawworks. Minimum pressure should be 110 psi. Drum Clutch – Indicates pressure of the air to either high or low drum clutch. Working pressure should be approximately 110 psi.

Make-up, Breakout Cathead Controls – Regulates flow of air to catheads. Push lever away from operator to engage cathead friction clutch. This lever is spring loaded and will return to the OFF position when the hand is removed. The slot in which the lever travels is offset to permit application of less than full air pressure when required for certain operations. The knurled knob at the right of the slot is a safety lock for the lever. Use this lock to prevent accidental engagement of cathead and possible serious injuries to personnel. Rotary Drive Clutch and Inertia Brake – This lever engages the rotary clutch when moved away from the operator. Move lever toward operator to engage the inertia brake. The operator should pause momentarily between disengagement of the clutch and engagement of the brake. Use the safety lock at the right side of the slot to prevent accidental engagement of cathead. Low and High Drum Clutch Control – Regulates flow of air to both the low and high drum clutches. Move lever into the left leg of “U” shaped slot to engage the low drum clutch and into the right leg of the “U” to engage the high drum clutch. 11.2

Mechanical Controls Transmission selection is achieved by manually raising or lowering shifter handles located on the front of the main control cabinet. The center position of the lever slot is neutral. At least one of the levers must be in neutral before any transmission selection can be engaged. Reverse-High Transmission Shifter – Lift the lever into its upper position to shift transmission to reverse. Placing the lever in its lower position shifts the transmission into high speed ratio. The center position of the lever slot is neutral. This lever must be in the neutral position before the second-low clutch can be engaged. Second-Low Transmission Shifter – Lift the lever into its upper position to shift transmission to second speed ratio. Placing the lever in its lower position shifts the transmission into low speed ratio. The center position is neutral. This lever must be in neutral position before the reverse-high clutch can be engaged. Low Drum-Catshaft Drive Shifter – The low drum drive and catshaft is engaged by placing this lever in its lower position, and disengaged by placing it in the upper position. Caution: Before shifting any manually operated clutches, master clutch should be released and inertia brake used to stop drawworks shaft rotation. Before engaging emergency low drive jaw clutch with the foot pedal, master clutch must be released.
