Last week my A/C compressor starting making all kinds of racket and the belt started to slip and burn. I checked the refridgerant and it was still full. I would like to replace the clutch on the compressor if that is the problem or if that is feasible for this compressor otherwise I'll have to replace the compressor(new one), expansion valve, and the R/D just so that the compressor stays within warranty. This is for an 82 300D turbo that PO had converted to R134a but I'm not sure as to when this was done or if the compressor was changed then or just flushed. I'm thinking if I had to replace the compressor I may just reconvert to R12 but time and money may be an issue with that.

I've used the search function but couldn't find anything on replacing A/C comp clutch.
