: AC Clutch Instal

12-08-09, 12:58 PM
My AC compressor bearing gave out and seized the pulley. managed to get everything back and now I just need to figure out the air gap. any ideas on where i could get this spec? i need to find the air gap between the AC clutch plate and the compressor plate.

If nobody here has the info, you may have to call the service department at the dealership and try to get it out of them.

What kind of Cadillac do you own?

Do you have to take the thing apart to adjust that gap?

We carry a rubber hammer and give it a clout when it doesn't go in:thepan:

I'd wondered if I could cause it to be nearer in - so that the magnetic force would be greater. Sometimes, slipping it into N and revving the engine gets me a tad more voltage and vibration, and then it goes.

I've tried to lube the center shaft with graphite dust, but no help.

Such a small relay to carry that current !! But it seems to be okay.

I own a 1994 cadillac fleet. I tried to press a new bearing into th pulley and ended up bending the pulley. new pulley cost ~130. found a reman. acdelco compressor for a lil less. i think im just going to buy the compressor and replace the whole thing. anyone done this before? looking for ideas.
