REAR CLUTCH (Continued)
When pressure is released from the piston, the
spring returns the piston to its fully released position
and disengages the clutch. The release spring also
helps to cushion the application of the clutch assem-
bly. When the clutch is in the process of being
released by the release spring, fluid flows through a
vent and one-way ball-check-valve located in the pis-
ton. The check-valve is needed to eliminate the pos-
sibility of plate drag caused by centrifugal force
acting on the residual fluid trapped in the clutch pis-
ton retainer.

DISASSEMBLY

(1) Remove fiber thrust washer from forward side
of clutch retainer.
(2) Remove input shaft front/rear seal rings.

(7) Remove input shaft snap-ring (Fig. 226). It
may be necessary to press the input shaft in slightly
to relieve tension on the snap-ring
(8) Press input shaft out of retainer with shop

sized press tool to support the retainer as close to the
input shaft as possible.
CLEANING
Clean the clutch components with solvent and dry
them with compressed air. Do not use rags or shop
towels to dry any of the clutch parts. Lint from such
materials will adhere to component surfaces and
could restrict or block fluid passages after assembly.
