CLUTCH SHELL/HUB INSPECTION

1. Separate primary chain, engine sprocket and clutch
shell/hub assembly.
2. Inspect engine sprocket for damage or excessive wear.
Replace as required.
3. Attach tools to compress clutch diaphragm spring and
remove pressure plate assembly. See
NOTE
The clutch hub and clutch shell are no longer pressed together.
There are no retaining rings securing the clutch hub to the
clutch shell. Once the pressure plate assembly has been
removed the clutch hub will slide out of the clutch shell.
4. Remove clutch pack. Disassemble, clean and inspect
clutch pack. See 5.5 CLUTCH, Clutch Pack Cleaning and
Inspection.
5. Disassemble adjusting screw assembly and inspect
bearing, release plate, and adjusting screw. See
5.5 CLUTCH, General.
6. Remove clutch hub from clutch shell. Inspect primary chain
sprocket and the starter ring gear on the clutch shell.
7. Inspect slots that mate with the clutch plates on both clutch
shell and hub.
8. See Figure 5-26. Inspect the clutch shell compensating
spring set.
NOTE
As you proceed around the back of the clutch shell, the com-
pensating springs go from being loaded to unloaded so it is
possible for the clutch springs to float and move during
inspection. This condition is normal.
9. See Figure 5-27. Inspect clutch shell needle bearing for
smoothness. Rotate the clutch shell while holding the
clutch hub. If bearing is rough or binds, it must be replaced.
See 5.6 PRIMARY CHAIN, Clutch Shell Bearing
Replacement.
