Inspection after removal
Clutch disc
If the contact surface shows signs of damage due to excessive heat, replace clutch disc and pulley.
Pulley
Check the appearance of the pulley assembly. If the contact surface of the pulley shows signs of excessive grooving, replace the clutch disc and pulley. The contact surfaces of the pulley assembly should be cleaned with a suitable solvent before installation.
