INSPECTION/REPAIR
1. See Figure 6-16. Wash all parts, except fiber (friction)
plates (18) and bearing (25), in cleaning solvent. Blow
dry with compressed air. Examine the clutch compo-
nents as follows:
a. Check all clutch plates for wear and discoloration.
b. Inspect each steel (drive) plate (19) for grooves.
c. Place each steel plate on a flat surface. Using a
feeler gauge, check for flatness in several places.
Replace any plates that are damaged or are warped
more than 0.006 in. (0.152 mm).
2. Check the diaphragm spring (11) for cracks or bent tabs.
Install a new spring if either condition exists.
3. See Figure 6-19. Check fiber plates for thickness.
a. Wipe the lubricant from the eight fiber plates and
stack them on top of each other.
b. Measure the thickness of the eight stacked fiber
plates with a dial caliper or micrometer. The mini-
mum thickness must be 0.661 in. (16.789 mm).
c. If the thickness is less than specified, discard the
fiber plates and steel plates. Install a new set of
both friction and steel plates.
4. See Figure 6-20. Check the clutch shell.
a. Inspect primary chain sprocket (1) and the starter
ring gear (2) on the clutch shell. If either sprocket or
ring gear are badly worn or damaged, replace the
clutch shell.
b. Check the slots that mate with the clutch plates on
both clutch shell (4) and hub (3). If slots are worn or
damaged, replace shell and/or hub.
c. If clutch shell was removed from motorcycle, check
the bearing for smoothness. Rotate the clutch shell
while holding the clutch hub. If bearing is rough or
binds, it must be replaced.
