re: GM compressor clutch adjustment
If I understand correctly, the nut on the hub may have come loose (or there is another reason for a wide gap), thus my gap is now about .125". As a result, it only engages infrequently, but engages every time when tapped with a wooden rod. Do I simply tighten the hub nut to shore up the hub and close the gap, or do I need the special tool to remove, look for shims, maybe reshim, and retighten ?
Thanks,
Biker Bil
No shims in this press fit design- "borrow" clutch tool from Autozone- remove clutch nut- apoply tool- adjust clutch to .020" see link below-
Note: the nut is only there for looks- keeps dirt out of threads- will NOT adjust clutch for you- it bottoms on end of shaft, not clutch driver.-- it was discontinued on later models.....

The number one A/C diagnostic tool there is- is to know how much refrigerant is in the system- this can only be done by recovering and weighing the refrigerant!!
Just a thought.... 65% of A/C failures in my 3200 car diagnostic database (GM vehicles) are due to loss of refrigerant due to a leak......
