AC Pully is grinding

my AC compressor pully is grinding. is it possible to just change the pully and or the bearing in the pully instead of replacing the whole compressor?

Well if you did you would have to be careful with the clutch asembly and I don't know if you need any special tools. Also then if you do all that work and it leaks then you just wasted all you refrigerent. I had a leak from the input shaft on our other car and for everything I had to do it was better to just to trade it and buy a rebuilt with a warranty.

No problem, you just need the right pullers. I think you'll need 2 pullers and a hydraulic press.

Look in your Factory Service Manual, it tells how to do it.

Or get the compressor number off it, then look up the number on the web -- for example Sanden 5145 or Mitshibishi 5145. Both were used on Jeeps. Lots of info available.

And you don't have to lose the refrigerant charge or remove the compressor - as long as you can reach it.
The bearing you'll have to get it from a bearing house - parts houses don't have them.

First be sure it's the clutch bearing. If it squeals or drags with the compressor OFF - it's the clutch bearing.

But if it does it with the compressor ON it's the bearing inside the compressor. The web will also show you how to rebuild the compressors.

If you get sparks flying out of it when the compressor is engaged - you need a new clutch. A new clutch it more expensive than a rebuild compressor with a clutch on t.
It's no wonder the country is falling apart - stupidity abounds!
