FRONT CLUTCH-RECONDITION
INSPECTION
Inspect plates and discs for flatness. They must not
be warped or cone shaped.
Inspect facing material on all driving discs.
Replace discs that are charred, glazed or heavily pit-
ted. Discs should also be replaced if they show evi-
dence of material flaking off or if facing material can
be scraped off easily. Inspect driving disc splines for
wear or other damage. Inspect steel plate surfaces for
burning, scoring, or damaged driving lugs. Replace if
necessary.
Inspect steel plate lug grooves in clutch retainer
for smooth surfaces, plates must travel freely in
grooves. Inspect band contacting surface on clutchretainer for scores, the contact surface should be
protected from damage during disassembly and han-
dling. Note ball check in clutch retainer, make sure
ball moves freely. Inspect piston seal surfaces in
clutch retainer for nicks or deep scratches, light
scratches will not interfere with sealing of seals.
Inspect clutch retainer inner bore surface for wear
from reaction shaft support seal rings. Inspect
clutch retainer bushing for wear or scores.
Inspect inside bore of piston for score marks, if
light, remove with crocus cloth. Inspect seal grooves
for nicks and burrs. Inspect seals for deterioration,
wear, and hardness. Inspect piston spring, retainer
and snap ring for distortion.

INSPECTION
Inspect facing material on all driving discs.
Replace discs that are charred, glazed or heavily pit-
ted. Discs should also be replaced if they show evi-
dence of material flaking off or if facing material can
be scraped off easily. Inspect driving disc splines for
wear or other damage. Inspect steel plate and pres-
sure plate surface for burning, scoring or damaged
driving lugs. Re place if necessary. Inspect plates and
discs for flatness, they must not be warped or cone-
shaped.
Inspect steel plate lug grooves in clutch retainer
for smooth surfaces, plates must travel freely in the
grooves. Note ball check in piston; make sure ball
moves freely. Inspect seal rings surfaces in clutch
retainer for nicks or deep scratches; light scratches
will not interfere with sealing of the seals. Inspect
neoprene seal rings for deterioration, wear and hard-
ness. Inspect piston spring and waved snap ring for
distortion or breakage.
Inspect teflon and/or cast iron seal rings on input
shaft for wear. Do not remove rings unless conditions
warrant. Inspect rear clutch to front clutch No. 2
thrust washer for wear. Washer thickness should be
.061 to .063 inch, replace if necessary.
DISASSEMBLY
Press out input shaft, if required.
