PUMP GP-AUXILIARY SEA WATER 1446081 - Caterpillar

START BY:a) remove final drives 1. Use an acceptable jack as shown to lift the side of the machine enough so that the wheel is off the ground.
Personal injury could be the result if bolts (2) are removed when the wheel is not off the ground. To prevent personal injury, make sure the wheel is off of the ground.
2. Put tool (A) in position in the groove in the final drive gear. Remove bolts (2) and retainer (3). Remove final drive gear and hub (1). The weight of the final drive gear and hub is approximately 171 kg (377 lb.). 3. Put blocks under gear (7) and hub (6) for support.4. Remove bolts (4) and retainers (5). Fasten a hoist to hub (6). Remove hub (6) from gear (7). The weight of hub (6) is approximately 78 kg (172 lb.). The weight of gear (7) is approximately 93 kg (205 lb.).Install Final Drive Gear And Hub
1. Put hub (1) in position in gear (2). The weight of hub (1) is approximately 78 kg (172 lb.). The weight of gear (2) is approximately 93 kg (205 lb.).2. Install retainers (3) and bolts (4) that hold the hub in position in the gear. 3. Use tool (A) and a hoist to put final drive gear and hub (5) in position on the axle housing. The weight of the final drive gear and hub is approximately 171 kg (377 lb.). 4. Install retainer (6) without the shims. Install five bolts (7) evenly spaced as shown. Turn the wheel. While the wheel is in rotation, tighten five bolts (7) to a torque of 35 N m (25 lb.ft.). Tighten each bolt one time only.5. While the wheel is in rotation, tighten bolts (7) to 70 N m (50 lb.ft.). Tighten each bolt one time only.6. Use tooling (B) to get the measurement between the outside face of retainer (6) and the end of the axle housing. Check distance at two locations.7. Use an outside micrometer to check the thickness of retainer (6). Check the thickness at two locations.8. Subtract the average thickness of retainer from Step 7 from the average distance from Step (6). This dimension is the distance between the end of the axle housing and the retainer.9. Remove bolts (7) and retainer (6). Add a thickness of shims equal to the dimension found in Step 8 plus 0.25 mm (.010 in.). Install the shims, retainer (6) and bolts (7). Tighten bolts (7) to a torque of 250 15 N m (184 11 lb.ft.).END BY:a) install final drives
