A/C Compressor Clutch replacement - Anyone?

My '96 GC 5.2L makes a pinging and rattling noise coming from the A/C clutch when the compressor cycles on and off. The dealer wants about $400 just for the clutch and more for other hardware they say is necessary. Pep Boys sells a refurbished compressor for $275 or a new one for $375 but I heard that they don't necessarily come with the clutch which is all I really need. Plus my A/C system has never been "unsealed" and I don't want to start now by changing out the compressor. If possible, just want to change out the clutch.

Anyone ever try it and are there any special tools required?

here are special tools for clutch removal Check with an older mechanic. I have a set, but found in the end to get yourself a new compressor. It's a no brainer install if you need help recharging IM me and i can walk u through it (BTW, the tool for clutch removal is worth more than a new comp.)
If a new comp doesn't have a clutch don't buy it, and stay away from the rebuilds

(1) disconnect and isolate negative battery cable
(2) Remove the compressor shaft bolt. A band-type oil filter wrench may be used to hold pulley
(3) Tap the clutch patch with a plastic mallet to release it from the splines on the comrpessor shaft. Remove clutch plate and shims from the compressor shaft
(4) Remove the pulley retaining snap ring with snap ring pliers and slide the pulley assembly off the compressor
(5) Remove the screw and retained from the clutch coil lead wire on the compressor front housing
(6) Remove the snap ring from the compressor hub and remove the clutch field coil. Slide the clutch field coil off of of the compressor hub


Theres some info on proper shim measurements.. But no special tools needed other then snap ring pliers and a small wooden block to tap it back on.

What Joe says.
If it's the clutch bearing, it alone can be replaced (check this thread):

replace the compressor -- mine went out too and its cheaper to replace the compressor rather than the clutch pulley assembly....

I second that recommendation. They are like $160 on fleaBay. Mine is chirping on the ZJ right now. I expect to need one soon enough.

Compressor Replacement

Guess the noise wasn't from the compressor after all becuase the water pump siezed when I started the engine a few days after I wrote that post. When the pump siezed, the belt woudn't turn so it pulled the power steering pump in and broke its mounting bracket. Very similar to what SJZ described in post #10 http://www.jeepforum.com/forum/showt...32#post3272932
Dealer wanted to bend me over for $950 to replace the water pump and power steering bracket. Found a shop that did it for $225 cash. No more noise.

I may still replace the compressor anyway as the vehicle is at 225,000 miles.

Thanks all for your comments. Very helpful.
