Inspection
NOTE: Where necessary, refer to the
specifications charts at the end ofthis
chapter for wear limits and tolerances.
1. Check the condition of the clutch
plates, both steel and friction plates. If
the steel plates are discolored, orif either
type is scored, replace the plates as a set.
2. Check the thickness ofthe friction
plates with a vernier caliper. If any plate
is below the service limit given, replace
the set. Check the tabs on the friction
plates which contact the housing for dam—
age. Minor deformities can be removed
with an oilstone, but removing too much
metal will result in excessive clearance
between the tabs and the housing and the
resultant backlash in the clutch.

3. Check the steel plates for warpage
by placing them on a flat surface and at—
tempting to slip a feeler gauge of the ser—
vice limit thickness between the plate
and the surface. Plates should be re—
placed as a set if warped.
4. Check the free—length ofthe clutch
springs. These components should be re—
placed as a set if any of them have col—
lapsed belowthe service limit.

5. Check the condition of the clutch
pressure plate, and replaceit if warped or
cracked or deeply scored.
6. Check the condition of the housing
gear, noting any worn or broken teeth. If
the gear teeth appear worn, carefully in—
spect those of the primary drive gear.
Gears which mesh should be replaced in
pairs if either one is worn.
7. Place the clutch housing on its
shaft and ensure that the housing does
not have excessive axial play. The hous—
ing must turn freely, however.
8. Check the condition of the clutch
housing. Note any indented wear on the
housing where the friction plates contact
it. If the indentations are minor, they can
be removed with an oilstone.
9. Roll the clutch pushrod on a flat
surface to ensure that it is not bent. If
bent, straighten or replace it.
10. Inspect the clutch hub for in—
