INSPECTION AFTER REMOVAL
Clutch Disc
If the contact surface shows signs of damage due to excessive heat, replace clutch disc and pulley.

5. Install the center bolt using Tool.• After tightening the center bolt to specification, check that the
pulley rotates smoothly.
INSPECTION OF CLUTCH DISC TO PULLEY CLEARANCE
1. Check the clearance around the entire periphery of the clutch
disc.
