Machine Preparation
Note: Cleanliness is an important factor. Before the removal procedure, clean the exterior of the component thoroughly. Cleaning the exterior will help to prevent dirt from entering the internal mechanism.
- Move the machine to a hard level surface away from operating machines and away from personnel.
- Engage the parking brake. Place wheel blocks in front of the wheels and behind the wheels.
- Stop the engine.
- Connect the steering frame lock. Refer to Disassembly and Assembly, "Steering Frame Lock - Connect and Disconnect".
- Turn the key start switch and the battery disconnect switch to the OFF position. If there is no battery disconnect switch, remove the negative battery cable at the battery.
- Release system pressure. Refer to Disassembly and Assembly, "System Pressure - Release".
Procedure
- Remove the final drive, brake, and wheel. Refer to Disassembly and Assembly, "Final Drive, Brake, and Wheel - Remove".
- Disassemble the final drive planetary carrier. Refer to Disassembly and Assembly, "Final Drive Planetary Carrier - Disassemble".
