Start By:
- Separate the transmission from the torque converter. Refer to Disassembly and Assembly, "Transmission and Torque Converter - Separate".
Note: Cleanliness is an important factor. Before the disassembly procedure, the exterior of the component should be thoroughly cleaned. This will help to prevent dirt from entering the internal mechanism.
Note: Put identification marks on all sections of the transmission for assembly purposes.
- Drain the transmission fluid into a suitable container for storage or disposal. The capacity of the transmission is 30 L (8 US gal).

- Use Tooling (E), a suitable air supply and the following procedure to measure the running clearance of the clutch pack:
- Place the shaft in the vertical position. End plate (W) that will be measured should be facing upward.
- Make sure that end plate (W) is free.
- Position the tip of Tooling (E) on end plate (W). Zero Tooling (E) .
- Apply air pressure of approximately 140 kPa (20 psi) to appropriate passage (Z) in the shaft for the clutch that is being checked.
Show/hide table
Personal injury can result from applying air pressure without the lock ring securely in place.
If the lock ring is not secure, the end plate and discs can suddenly come out with great force.
Make sure lock ring is securely in place before applying air pressure to clutch pack.
- End plate (W) should move upward and end plate (W) should contact retaining ring (X). The dial indicator will display the distance between end plate (W) and retaining ring (X). This is the running clearance of the clutch pack. For the proper running clearance, refer to the Testing and Adjusting, "Transmission Clutch Running Clearance - Check" for the machine that is being serviced.
