Ac compressor repair.

You need to properly diagnose the problem. Don’t just jump into parts replacement mode. Get an experienced a/c technician involved. Doesn’t need to be tractor specific.

All mobile a/c systems operate pretty much the same. The parts may be unique to the manufacturer but the diagnosis is generic.

Are you saying the clutch drops out after the compressor runs for a bit, or are you saying the whole thing locks up solid and stops turning, smoking the belt? The former is more easily solved than the latter.

It most likely isn’t a defective clutch. To much pressure causes belts squalling and clutch slipping. Sir I’m with the guy that suggested a professional ac tech. Please follow up with us

Silly question but have you cleaned and blew out the condenser and all the stuff up in the front. At first I was thinking your compressor had locked up. That causes your symptoms of belt slipping and stuff

Basically I get cold air from the outlet, but then it stops, I hear a squeal from the engine. Belt isn't moving the pulley like it should. Can I just replace the clutch?

It's not a clutch problem. Sounds like the system is over charged or the compressor is cratered already. And it's not as simple as just replacing the compressor.

We saw at the beginning of all this something about borrowing gauges. So far, no report on how that worked out. Just a lot of "it might be this, it might be that, do this, do that."

A/C servicing works best with gauges involved rather than guesswork.

This is perhaps the most informative website on 12V air conditioning on the web and offers an excellent explanation of how/why each component works: Resource Hub - BTRAC

The issue can be as simple as a loose drive belt, or as complicated as you can imagine.
