COMPRESSOR

1. Check the clearance around the entire periphery of the clutch

disc.

2. If specified clearance is not obtained, 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.
