How do I adjust the air gap on the A/C compressor clutch ?

i have never had one with that gap. i set them at .017-.020. the clutch is bad if it is making noise. you will need to replace it. Roy

There is 2 bearings in the front of a compressor. When the clutch is disengaged you use the one in the clutch, when the clutch is engaged you run on a bearing in the front of the compressor. I would suspect it.
