Overhaul (Subassemblies)

4C RETAINER/BULKHEAD
DISASSEMBLY





1. Remove the 2C piston belleville spring snap-ring from the 4C retainer /bulkhead (Fig. 50).
2. Remove the 2C piston Belleville spring from the retainer/bulkhead (Fig. 50).
3. Remove the 2C piston from the retainer/bulkhead. Use 20 psi of air pressure to remove the piston if necessary.
4. Remove the 4C clutch snap-ring from the retainer/bulkhead (Fig. 50).
5. Remove the 4C clutch pack from the retainer/ bulkhead (Fig. 50).
6. Using Spring Compressor 8250 and a suitable shop press, compress the 4C piston return spring and remove the snap-ring (Fig. 50).
7. Remove the 4C piston return spring and piston from the retainer/bulkhead (Fig. 50). Use 20 psi of air pressure to remove the piston if necessary.

ASSEMBLY
1. Clean and inspect all components. Replace any components which show evidence of excessive wear or scoring.
2. Install new seals on the 2C and 4C pistons (Fig. 50).
3. Lubricate all seals with Mopar ATF +4, type 9602 prior to installation.
4. Install the 4C piston into the 4C retainer/bulkhead (Fig. 50).
5. Position the 4C piston return spring onto the 4C piston.





6. Using Spring Compressor 8250 and a suitable shop press, compress the 4C piston return spring and install the snap-ring (Fig. 51).
7. Assemble and install the 4C clutch pack into the retainer/bulkhead (Fig. 50) with the steel separator plate against the piston.
8. Install the 4C reaction plate and snap-ring into the retainer/bulkhead (Fig. 50). The 4C reaction plate is non-directional.
9. Measure the 4C clutch clearance. The correct clutch clearance is 0.81 - 1.35 mm (0.032 - 0.053 inch). The snap-ring is selectable. Install the chosen snap-ring and re-measure to verify the selection.
10. Install the 2C piston into the retainer/bulkhead (Fig. 50).
11. Position the 2C Belleville spring onto the 2C piston.
12. Position the 2C Belleville spring snap-ring onto the 2C Belleville spring (Fig. 50).





13. Using Spring Compressor 8249 and a suitable shop press (Fig. 52), compress the belleville spring until the snap-ring is engaged with the snap-ring groove in the retainer/bulkhead.
