5. Using holder to prevent clutch disc rotation.After tightening bolt, make sure pulley rotates smoothly.
6. Check clearance around entire periphery of clutch disc. If specified clearance is not obtained, replace adjusting spacer
and readjust.
Break-in Operation
When replacing compressor clutch assembly, always carry out break-in operation. This is done by engaging
and disengaging clutch about thirty-times. Break-in oper ation raises the level of transmitted torque.
