The electromagnet on an automotive a/c compressor, can it get 'weak'? As PENG would put it, "is it sleeping a lot"? I have removed the shim which took the gap down from 49 (kinda sloppy) to 16 (kinda tight) thousandths. I'll see if that helps the clutch stay engaged. But anyway, can that magnet get weak?
EDIT: If my truck blows up, I am going be a little embarrassed.
2nd EDIT: I also put a couple a drops of some mystery oil (I mean I have no idea what kind of oil it is not actual Mystery Oil) on the three little clutch springs. Actually the first attempt was to sand the rust off the plates. That got me some further before melt down. I just did the shim removal and oil thing now but have not had it out for the long haul. As sweet as I think it all might be, who needs the drive when I could be doing this and listening to Itzhak?
