a. Check the inner splines (Figure 30) on the
clutch plates. Minor roughness can be
cleaned with an oilstone or fine file. If any
one plate has excessive roughness or wear, re-
place all the clutch plates as a set.
NOTE
The clutch plate thickness does not
apply to clutch plate No. 1. Clutch
plate No. 1 is much thicker than the
seven standard clutch plates.
b. Measure the thickness of each clutch plate at
several places around the plate. If any plate is
worn to the service limit, replace all the clutch
plates as a set.
c. Check the clutch plates for warp on a surface
plate or a piece of plate glass (Figure 31). Re-
place all the clutch plates as a set if the warp
in any plate equals or exceeds the service
limit in Table 1.
4. If clutch plate No. 1 was disassembled from the
clutch boss, perform the following:
a. Measure the thickness of clutch plate No. 1 at
four places around its circumference. Replace
it if any measurement exceeds the service
limit.
b. Check the warp on a surface plate or piece of
plate glass (Figure 31). Replace clutch plate
No. 1 if its warp equals or exceeds the service
limit.

nicks or galling where they come in contact
with the friction disc tabs. They must be
smooth for chatter-free operation. If there is
any excessive damage, replace the clutch
housing and inspect the friction disc tabs for
excessive wear.
b. Inspect the bushing in the housing for discol-
oration or other signs of heat damage.
c. Check the primary driven gear (A, Figure 23)
on the clutch housing for tooth wear, damage
