HUB AND PULLEY INSPECTION
NOTE: The compressor drive hub and the pulley and bearing assembly can not be serviced separately from the A/C compressor. In the event of drive hub or pulley and bearing assembly damage or failure, the A/C compressor, drive hub and pulley and bearing must be replaced as an assembly.
NOTE: Typical clutchless compressor drive hub and pulley and bearing assembly shown.
The bridges (1) located on the non-servicable compressor hub (2) are designed to break away in the event of compressor seizure. Examine the bridges for separation or cracks (3). Damage to the bridges are an indication of excessive compressor torque, which is most likely caused by compressor failure.
Check the non-servicable pulley bearing (4) for roughness or excessive noise. Check the pulley dampeners (5) for excessive play which can be caused by deterioration or damage. Inspect the belt surfaces of the non-servicable pulley (4) for wear. If the pulley surfaces are oily, inspect the shaft and nose area of the A/C compressor for refrigerant oil. If refrigerant oil is found, the compressor shaft seal is leaking and the A/C compressor must be replaced.
Replace the A/C compressor if wear or damage is found to the drive hub or pulley and bearing assembly A/C Compressor - Removal.
