4C Retainer/Bulkhead
RETAINER/BULKHEAD-4CDISASSEMBLY
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 (10) and remove the snap-ring (9).
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.
1. Install new seals (1, 11) on the 2C and 4C pistons.
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.
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 0.77 - 1.39 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 (5) until the snap-ring (6) is engaged with the snap-ring groove in the retainer/bulkhead.
