Tires of different type (1) Obey the tire mixability precautions (Ref. AMM TASK 32-41-00-910-001). B. Installation of the NLG Wheel CAUTION: MAKE SURE THAT THE GREASE USED FOR THE AXLE SLEEVE IS THE SAME AS THE GREASE USED FOR THE BEARINGS (CONE AND CAGE). IF YOU USE A DIFFERENT GREASE, YOU CAN CAUSE DAMAGE TO THE BEARINGS. (1) Preparation for installation (a) Make sure (if the tire mixability is not permitted) that the wheel for installation has the same type of tire (radial cross-ply) as the other wheel on the NLG. (b) Make sure that the retaining ring (11) is in its housing. (c) Clean the axle sleeve (1) and with Material No. 08BBB1 (Non Aqueous Cleaner-- Petroleum Based -) and dry it with filtered compressed air. (d) Make sure that the axle sleeve (1) is in the correct condition. (e) Apply a light coat of Material No. 03HBD9 or 03-GBB1 or 03-GCB1 on the axle sleeve (1) and the threads of the axle.
