Retainer/Bulkhead-4C
RETAINER/BULKHEAD-4CDISASSEMBLY
4C Retainer/Bulkhead Components:
1. Remove the 2C piston Belleville spring snap-ring (6) from the 4C retainer/bulkhead (13).
2. Remove the 2C piston Belleville spring (5) from the retainer/bulkhead (13).
3. Remove the 2C piston (2) from the retainer/bulkhead (13). Use 20 psi of air pressure to remove the piston if necessary.
4. Remove the 4C clutch snap-ring (7) from the retainer/bulkhead (13).
5. Remove the 4C clutch pack (3, 4, 8) from the retainer/bulkhead (13).
6. Using Spring Compressor 8250 (2) and a suitable shop press (1), compress the 4C piston return spring and remove the snap-ring.
4C Retainer/Bulkhead Components:
7. Remove the 4C piston return spring (10) and piston (12) from the retainer/bulkhead (13). Use 20 psi of air pressure to remove the piston if necessary.
ASSEMBLY
NOTE: Clean and inspect all components. Replace any components which show evidence of excessive wear or scoring.
4C Retainer/Bulkhead Components:
1. Install new seals (1, 11) on the 2C and 4C pistons or in the piston retainers.
2. Lubricate all seals with Mopar ATF +4 prior to installation.
3. Install the 4C piston (12) into the 4C retainer/bulkhead (13).
4. Position the 4C piston return spring (10) onto the 4C piston (12).
5. Using Spring Compressor 8250 (2) and a suitable shop press (1), compress the 4C piston return spring and install the snap-ring.
4C Retainer/Bulkhead Components:
6. Assemble and install the 4C clutch pack (3, 4) into the retainer/bulkhead (13) with the steel separator plate against the piston.
7. Install the 4C reaction plate (8) and snap-ring (7) into the retainer/bulkhead (13). The 4C reaction plate is nondirectional.
8. Measure the 4C clutch clearance. The correct clutch clearance is 0.770 - 1.390 mm (0.030 - 0.055 inch). The snap-ring (7) is selectable. Install the chosen snap-ring and re-measure to verify the selection.
9. Install the 2C piston (2) into the retainer/bulkhead (13).
10. Position the 2C Belleville spring (5) onto the 2C piston (2).
11. Position the 2C Belleville spring snap-ring (6) onto the 2C Belleville spring (5).
12. Using Spring Compressor 8249 (2) and a suitable shop press (1), compress the Belleville spring until the snap-ring is engaged with the snap-ring groove in the retainer/bulkhead.
