Can the AC clutch bearing be replaced on a 1995 Pathfinder?

If so, who sells it?

The clutch is vey expensive.

The clutch bearing is sold as part of the clutch assembly, not seperate. Because of the cost of the clutch, many will replace the whole compressor and clutch assy. with a reman. unit as it is usually not a whole lot more than the cost of the clutch assy. alone. This also saves one from having to deal with possibly adjusting the clutch gap.

I did find an illustration that is suppose to be from a repair manual showing pulling the clutch from the pulley. I tried a puller and was afraid that something was going to break as I tightened it so much. It is difficult to tell if I moved it any at all.

Autozone sells the AC compressor clutch bearing.

Yeah, there's a special tool to remove and install the clutch. Also, there are shims (actually small washers) used to set the clutch gap. Make sure you have the proper clutch gap after you reinstalled the clutch assy.

So what is this "special tool"? I have a puller that uses the 3 threaded holes in the front of the clutch.

Just an AC clutch remover/installer. Sounds like you have it! Air gap for the clutch is .012-.024 inch. Tool typically will look something like this:

Yes that looks like the puller kit that I got on loan from AutoZone because my pullers are all too big. The shiny round piece is in these kits is aluminum. I have no idea why anyone thought that was a good design idea. I stripped some of the threads out of it trying to pull this clutch plate. I don't know if it will come off without breaking something or stripping out the small 5-mm bolts. There is a bushing or spacer that the retaining bolt goes through. I have the pulley pushing against that to remove the plate.

The compressor is labeled:
Calsonic
Part # 92600 57G00

There is a red label on it with "506021-1661".

OK, I think I am done now. I sprayed PB Blaster on the center of the clutch plate the last two days to see if that would help. I tried the puller again a few minutes ago, and it pulled one of the 5-mm bolts through the threaded holes on the plate. The plate now has a gap of about 0.052" on one side and 0.062" on the other. I don't know if the plate bent out some or what but I do not know anything else I can do for it.

For anyone who has worked on an AC clutch on a GM, Ford, or Chrysler, those are a piece of cake and this is a pain in the butt. The only good part of this is that the AC has its own drive belt. When the clutch bearing finally seizes up, the belt can be cut and the PathFinder will still be drivable.
