and 240) and outer sealrings (241 and 242)
onto pistons (237 and 238). The lips of all
the sealrings must be toward the piston
cavities of the center support.
NOTE
If the pistons are not installed to the
bottom
of
their
cavities
during
installation of self-locking retainer rings
(243 and 244) proper clutch clearance
cannot be established.
(d) Temporarily place second clutch piston
