Inspection
Inspect the friction material on all driving discs. Re
place discs that are charred, glazed, heavily pitted, flak
ing, or if the friction material can be scraped off easily.
Inspect internal splines for wear or other damage.
Inspect the steel plates and pressure plate surfaces for
overheating, scoring, and damaged driving lugs and re
place as necessary.
Inspect the steel plate lug grooves in the clutch re
tainer for smooth surfaces. The plates must slide freely
in the grooves.
Inspect the band application surface on the clutch
retainer for nicks and scores. Remove light scratches
and nicks with crocus cloth.
Inspect the check ball in the clutch retainer. The ball
should move freely in its cage.
Inspect the seal ring surface inside the clutch retainer
for nicks or deep scratches. Light scratches will not
interfere with sealing of the rings. Inspect the clutch
retainer bushing for scores and wear from the reaction
shaft support sealing rings and lands.
Inspect the inner bore of the piston for score marks.
Remove light scores with crocus cloth. Inspect the seal
ring grooves for nicks and burrs. Inspect the piston
springs, retainer, and snap ring for distortion.
Retainer Bushing Replacement
(1) Place clutch retainer, with open end facing
downward, on clean, smooth surface.
(2) Insert Bushing Remover/Installer Tool J-24039

is flush with base of bore chamfer (fig. 2C-75).
Assembly
(1) Lubricate inner seal with petroleum jelly and
install it o.n hub of clutch retainer.
NOTE: Be sure the seal lip faces into the piston bore
and is properly seated in the seal groove.
(2) Lubricate outer seal with petroleum jelly and
install it on clutch piston with seal lip facing into piston
bore.
(3) Install piston assembly in retainer and carefully
seat piston at bottom of retainer bore.
(4) Install clutch piston springs on piston (fig. 2C-
76). Install nine or eleven springs in clutch (according to
original number in clutch).
(5) Install spring retainer and snap ring over
springs.
