2nd Gen Non-Engine/Transmission How To Pull A/C Clutch? Bad Squeal.

[Jeff H]

My Haynes manual doesn't cover this. How do you pull A/C clutch? Also how to reinstall clutch.

I seam to have a high pitch squeel coming from the a/c compressor. But it does it with clutch engaged and disengaged. Seam to only squeel only when its humid outside.

I found this by taking a piece of tubing. Holding one end up to my ear. Then take the other end of the tubing and listened to all the pullies. Its definatly coming from the a/c compressor. But don't understand why it does it engaged and disegaged??

I replaced mine last year. Two of the little flat springs that hold the clutch face away when not engaged had broken and the face was rubbing against the pulley all the time. You will not be able to find an AC clutch for the '95 but the one from later years will work, you just have to change out the electrical plug.



The biggest thing is do not pull against the shaft. The pulley that the belt runs on is on a bearing that fits on the housing of the compressor. The clutch "plate" is mounted on the shaft. It has 3 holes in it that you can screw some bolts into to pull the "plate" off with. I can't remember if they are 1/4-20 or 6mm. There can be several shims under the plate to create the proper gap between the clutch plate and the pully. I can't remember what the gap should be, seems like it was . 020-. 030. The pulley can be removed after you remove a circlip that is under the clutch plate. I bought a cheap pair of snap ring pliers with large tips at the parts house and bent them to get to it. After you remove the snap ring you can pry the pulley off by prying against the compressor housing itself. Once again, do not pull or pry against the compressor shaft.

What year can you get a clutch for. I have a 99 and can only get the clutch and compressor together.
