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 cont act 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.
Coil
Check the magnet coil for a loose connection or cracked insulation.

INSPECTION OF CLUTCH DISC TO PULLEY CLEARANCE
1. Check the clearance around the entire periphery of the clutch
disc.
2. If specified clearance is not obt ained, replace compressor clutch.
BREAK-IN OPERATION
When replacing compressor clutch assembly, always conduct the break-in operation. This is done by engag-
ing and disengaging the clutch about 30 times. Break-in operation raises the level of transmitted torque.
