Compressor Pulley: Service and Repair

MANUAL

DISASSEMBLY

CLUTCH HUB AND PULLEY
1. Remove the clutch hub retaining bolt with the aid of a spanner wrench.




2. Pull the clutch hub. If the hub can not be pulled from the compressor shaft, screw an 8 mm bolt into the shaft hole of the clutch hub to force the hub from the shaft.




3. Remove the pulley retaining snap ring and then pull the pulley and bearing assembly from the compressor.




REASSEMBLY
1. After reassembling the compressor assembly by the reverse of the disassembly procedure given, check the clutch air gap between the clutch hub and the pulley mating surface with a feeler gauge. The air gap should be as follows.

Air gap: 0.35 - 0.65 mm (0.014 - 0.026 inch)

NOTE: When reassembling the compressor assembly, clean the pulley bearing surface and coil press diameter of the front head to remove any dirt or corrosion.

2. If the clutch air gap is not within the dimensions specified above, adjust the various thickness shims until the air gap is within the specified limits.
