Inspection
Inspect friction material on driving discs. Replace
discs that are charred, glazed, heavily pitted, flaking or
if the friction material can be scraped off easily. Inspect
the driving disc inner splines for wear or other damage.
Inspect the steel plates and pressure plate surfaces for
over heating, scoring, and damaged driving lugs. Inspect
all discs and plates for distortion. Replace warped or
coned discs or plates.
Inspect the steel plate lug grooves in the retainer for
smooth surfaces. The plates must slide freely in these
grooves. Inspect the clutch piston ball check. The ball
should move freely in its cage. Inspect the seal ring
surfaces in the clutch retainer for nicks or deep
scratches. Light scratches will not interfere with seal
ing. Inspect the piston spring, wave spring, and spacer
for distortion or breakage.
Inspect the seal ring grooves in the input shaft and
piston retainer for nicks, burrs, and wear.
Inspect the rear clutch to front clutch thrust washer.
The washer should be 0.061 to 0.063-inches (1.55 to 1.60
mm) thick.
