The Dude Posted May 30, 2014 Share Posted May 30, 2014 Maybe someone can help me out with this problem. I vaguely remember something about removing a spacer/shim in the AC clutch. I have tried, with no success, to "search" for posts related to this problem. When the AC clutch wears it goes out of spec. Removing the spacer/shim puts the clutch back to specified air gap. Thanks.

Fairtax4me Posted May 30, 2014 Share Posted May 30, 2014 I have no idea where I read it, but I know I've seen something about this before as well. Does your clutch engage but still slip? Quote Link to comment Share on other sites More sharing options...
The Dude Posted May 30, 2014 Author Share Posted May 30, 2014 Apparently, when the clutch wears the gap becomes to great for the electromagnet to reliably engage. Removing the spacer/shim reduces the gap. This is my first post on this new board. Did the old posts on the other board carry over to this boarr?

Fairtax4me Posted May 30, 2014 Share Posted May 30, 2014 I would make sure the clutch is being commanded to engage before pulling it apart. You could also jumper 12v straight to the clutch to see if it works. You can also check the air-gap with a feeler guage and compare that to spec (if you can find the spec). I'm pretty sure most of the old posts were carried over. We've had a few thread resurrections lately where the last posts were made back in 2009-2011. I've searched for various threads and found plenty that were older than that. Quote Link to comment Share on other sites More sharing options...
Rooster2 Posted May 31, 2014 Share Posted May 31, 2014 (edited) Could it be that your system is low at the marginal level of refrigerant, to the point that the compressor may or may not turn on?? If so, add a can of 134, and also a can of leak detector. If you can get the compressor to engage for a while, then start looking for the green fluorescent dye to find the leak.
