4C RETAINER/BULKHEAD
DISASSEMBLY
(1) Remove the 2C piston belleville spring snap-
ring from the 4C retainer /bulkhead (Fig. 53).
(2) Remove the 2C piston Belleville spring from
the retainer/bulkhead (Fig. 53).
(3) Remove the 2C piston from the retainer/bulk-
head. Use 20 psi of air pressure to remove the piston
if necessary.
(4) Remove the 4C clutch snap-ring from the
retainer/bulkhead (Fig. 53).
(5) Remove the 4C clutch pack from the retainer/
bulkhead (Fig. 53).
(6) Using Spring Compressor 8250 and a suitable
shop press, compress the 4C piston return spring and
remove the snap-ring (Fig. 53).(7) Remove the 4C piston return spring and piston
from the retainer/bulkhead (Fig. 53). 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. 53).
(3) Lubricate all seals with MopartATF +4, type
9602 prior to installation.
(4) Install the 4C piston into the 4C retainer/bulk-
head (Fig. 53).
(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. 54).
(7) Assemble and install the 4C clutch pack into
the retainer/bulkhead (Fig. 53) with the steel separa-
tor plate against the piston.
(8) Install the 4C reaction plate and snap-ring into
the retainer/bulkhead (Fig. 53). The 4C reaction plate
is non-directional.
(9) Measure the 4C clutch clearance. The correct
clutch clearance is 0.77-1.39 mm (0.030-0.055 in.).
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/bulk-
head (Fig. 53).
(11) Position the 2C Belleville spring onto the 2C
piston.
(12) Position the 2C Belleville spring snap-ring
onto the 2C Belleville spring (Fig. 53).
(13) Using Spring Compressor 8249 and a suitable
shop press (Fig. 55), compress the belleville spring
until the snap-ring is engaged with the snap-ring
groove in the retainer/bulkhead.
ADAPTER HOUSING SEAL
REMOVAL
(1) Remove the transfer case from the transmis-
sion.
(2) Using a screw mounted on a slide hammer,
remove the adapter housing seal.
INSTALLATION
(1) Clean the adapter seal bore in the adapter
housing of any residue or particles remaining from
the original seal.
(2) Install new oil seal in the adapter housing
using Seal Installer C-3860-A (Fig. 56). A properly
installed seal is flush to the face of the seal bore.
(3) Install the transfer case onto the transmission.
