A/C clutch replacement

Has anyone ever replaced a A/C clutch before? If so is it easy to do. My A/C clutch is going bad and if I can replace the clutch I would rather do that then by a new compressor and everything else.

I am pretty sure. Its making a grinding noise and I can see where it has been leaving dust from grinding together. If I leave the A/C on its fine but as soon as I turn it off you can hear it making all kinds of noise.

Mine will engage for a second or two and then disengage. Is that the symptom for the pressure switch?

A/C clutches are simple to replace as long as you set the proper clearance (most use variable thickness shims ).... but your problem sounds like it might be a little more detailed. I've found few reasons to replace an A/C clutch other than a shorted or open coil. Since yours engages and works OK but makes noise when not engaged, I'd be suspect of a compressor bearing.... that is if I understand your problem correctly.

When I have the truck running and I watch the compressor the pulley for the belt seems to grind against the clutch part. I also smelled something burning the other day and it looks like the electrical connection directly behind the clutch started to melt I am guessing because of the grinding together and heating up. I think I am going to try and order a clutch and replace it. I really dont want to put another compressor on there if I dont have to although its only $100 more than the clutch.
