A/C Clutch replacement

[Roketdriver]

I let the clutch cool down then ran the engine again.

Clutch temperature before:

AC vent prior to starting:

AC after running for 30 seconds:

AC clutch after it started to make horrible squealing noises and I shut it off:

I'm now hating the idea that it's the compressor locking up. The belt has also lost some tension.

I retensioned the belt and ran it again for another few mintues. When the assembly hit 260* I shut it back off

IIRC there is another how to thread on replacing the bearing there, I want to say it includes a NAPA part #. The TEQ hefe’s on here that know TEQ parts availablility may chime in, but IIRC just the bearing rather was not available or is NLA. Let me find that thread. Had pics and the whole deal.

The A/C compressor starting whining/buzzing/vibrating soon after getting doused in a water crossing. Tested belt tension and idler pulley; all good. Hoping it's the clutch. Has anyone here replaced the clutch, and if so did the unit hold up? Autozone has one for $68; versus $414 for the whole compressor.

This was one of the threads I was referencing during this process, the AC clutch I put in had a brand new bearing in it though. I'm wondering if I possibly tapped it on too hard?

Never been in so I don’t know first hand

Went back out to the garage today to see if I could back the bearing off enough to remedy the friction issue.

I gave the puller one turn too many and broke the end of the snout off.

RIP compressor, off to a shop the LX will go.
