Also, check gear side clearance with a straight
edge and a feeler gauge (See Specifications).
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. Re-
place discs that are charred, glazed or heavily pitted.
Discs should also be replaced if they show evidence 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 clutch re-
tainer for scores, the contact surface should be pro-
tected from damage during disassembly and
handling. 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. In-
spect clutch retainer inner bore surface for wear from
reaction shaft support seal rings. Inspect clutch re-
tainer 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. Re-
place discs that are charred, glazed or heavily pitted.
Discs should also be replaced if they show evidence 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 re-
tainer for nicks or deep scratches; light scratches will
not interfere with sealing of the seals. Inspect neo-
prene 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.
