Rebuilding A/C Compressor

[Ben's Z]

Has anyone tried to rebuild their own A/C Compressor? Any luck? I didn't see any reman units at least through RockAuto.com available for my 77. I had some sort of slow freon leak. I got new hoses made and would like to complete the job with a reman compressor.

The most likely cause of a slow compressor leak is a worn oring at the input shaft. These orings need to be lubricated periodically. Everyone should run their AC at least a few minutes every month to recirculate oil to the oring. When I lived in Chicago, this was a common problem when the AC went for six months without ever being turned on. Since I moved to Florida 29 years ago, I have never heard of anyone having this problem.

As for whether you can do the repair yourself, I've never attempted it.
