The clutch puller for older GM compressors use a course thread 7/8” x 14 sae threads and will not work on our compressor clutch. If you try to use the older 7/8” x 14 thread puller you will trash the first 4 threads in the clutch.
Another option might be using something wide and flat like putty knives or kitchen knives to wedge the clutch back far enough not to grind.
I do think my tool is 7/8 x 14. Just measured it by my tape measure but it looks like 7/8. No wonder it would not start. I may try the correct metric one if I can find it.
Also, the idea about prying it out a bit, where exactly would I pry? And this would be with the 13mm nut removed from the middle shaft I am guessing.
I sprayed a bit of WD 40 on it this morning because after messing with it the noise was a bit louder than usual. It did help a good bit and the ride home was quiet.
