NOTE the bearing goes between the press tool and the clutch.
I apologize if I do not understand what you are asking but if the a/c compressor will not cycle then you will need to check the pressure switch but on some of the GM cars and trucks they have what is called a variable displacement compressor, meaning that the a/c compressor with not cycle while its on.......
You may have a bad compressor clutch coil, you need to check the coil and work from there................
What specific kind of vehicle do you have? It does sound like the clutch may be bad, but we also need to know what you are working on. You need to run power straight from the battery to the compressor. If is still does not engage then you need to replace the compressor and clutch, they are dead. If they do engage, then you have a wiring or computer issue.
If the AC pulley is locking up when the ac compressor clutch engages, it's not a clutch problem, it's a compressor problem. But yes, the AC clutch can usually be replaced separately. The problem is, if the clutch is worn out the compressor is probably worn out as well. It usually isn't that much more to replace the whole thing.
The compressor clutch does not need to be shimmed. The outside disc is pressed on until the proper air gap is achieved. If it is pressed on to far it has to be pulled off and reinstalled.
Need more info like year, make and model.
I am sure you can - but the clutch is abpout the same price as a rebuilt compressor. So last time i did this I bought the compressor, removed the cluth, and put it on my car compressor. I still have a compressor if I need one. Be sure your compressor is not locked up before you go buy anything.
I need to know the type of compressor (make) before I can answer that question.
Do y need puller to replace ac clutch on compressor. 2004 expition
If it is working fine, and the noise is only when it is disengaged you should only need to change the clutch on the compressor not the entire compressor. If there is room to pull the clutch off on the truck, then there is no need to evacuate the refrigerant.
It should. I've not seen a new compressor that didn't have a clutch but, you won't find out for sure by asking W.A. You need to take that up with the shop you're buying it from.
No, oil will ruin the clutch. Noise that sound like you need oil means a bearing or the compressor has failed.
