FINAL DRIVE GP 2276195 - Caterpillar

Remove Main Drive Gear And Output Shaft
start by:a) remove clutch hubs1. Turn the transmission housing as shown. 2. Remove bolts (1) that hold rear cover to the housing. 3. Install two 7/16"-14 NC forged eyebolts and tooling (A) to the rear cover. Fasten a hoist to the eyebolts and the tooling.
The pinion gear assemblies can fall against the housing and cause damage to the bearings.
4. Remove main drive gear and output shaft assembly (2) slowly to prevent damage to the pinion gear assemblies. Weight is 565 lb. (254 kg). Remove tooling (A) and the two eyebolts. 5. Remove pinion gear assemblies (3). 6. Remove two bearing cones (4) from the pinion gear with tooling (B) and a press.7. Do Step 7 for the other pinion gear assembly. 8. Remove output shaft bearing cup (5) and two pinion bearing cups (6) from the housing, if necessary. 9. Fasten tooling (A) and a hoist to main drive gear and output shaft assembly and rear cover (2). Lift the assembly as shown.10. Remove O-ring seals (7) and (8) from the rear cover.Install Main Drive Gear And Output Shaft
1. Check all parts for damage. If damaged, use new parts for replacement.2. Make sure all parts are clean and free of dirt and foreign material. 3. Fasten tooling (A) and a hoist to main drive gear and output shaft assembly and rear cover (1). Lift the assembly as shown. Weight is 565 lb. (254 kg).4. Install O-ring seals (2) and (3). 5. Install the two pinion bearing races with tooling (B) in the housing if removed. The output shaft bearing cup can be installed with acceptable tooling. 6. Lower the temperature of the output shaft bearing cup (4) and install in the housing, if removed.7. Heat two bearing cones (5) to a maximum temperature of 275°F (135°C). 8. Put bearing cones (5) in position on the pinion gear.
When bearing cones (5) get cool, use a force of 16,000 to 20,000 lb. (71 200 to 89 000 N) to push the cones against the shoulders on the pinion gear.
9. Do Steps 7 and 8 for the other pinion gear. 10. Put pinion gear assemblies (6) in position in the housing. Put 7M7260 Liquid Gasket Material on the contact surfaces between the rear cover and the housing. 11. Install two 7/16"-14 NC forged eyebolts (7) and tooling (A) to main drive gear and output shaft assembly (8). Fasten a hoist to the eyebolts and the tooling.
Make an alignment of pinion gears and main drive gear.
12. Lower the assembly slowly into the housing. Make sure pinion gears are in alignment. Install the bolts that hold the rear cover in position.end by:a) install clutch hubsDisassemble Main Drive Gear And Output Shaft
