Well actually, I pulled mine apart mainly out of curiosity. I think its possible to rebuild one, but "they" say you have to have hospital clean like facilities. I think thats a bit overblown. I think if you have a clean room, and are careful to keep dirt out, you'd be OK.
I don't know where you'd get the rings and/or the reed plates which are all you really need.
I bought a new Azone compressor and stayed away from the chain-store remans cuz of the bad track record they have. Knowing that I heard and experienced the SAME story with the alternator, I'd say it was true.
All of my A/C is new, other than the suction/manifold/high pressure line assembly. All parts from Azone other than the liquid line, pressure switch, and r134 adapters. In my case, that included compressor, new more efficient condenser (just to be safe), liquid line, evaporator, accumulator. Now... IF your compressor is good, then you can get by possibly with just the evaporator, new accumulator, new Orings, and a good flush. Your system may be fairly clean.
Its your call on how you want to proceed. With an old compressor, it may be on its last legs. It may have worn rings (they're just like piston rings but made of teflon/plastic) that aren't up to a long term job, or.. it may last forever. In that case, chances are your condenser and liquid line (hence the Otube) are just fine and can be flushed.
MO, is you don't have anything to loose by pulling the old compressor apart and inspecting the cylinders, pistons, etc. A good cleaning and polishing and oiling with 2oz of POE (ester oil) and it might hold up fine. If you find no evidence of the rings coming apart, then the condenser should be OK. The compressor has 2 case halves, and 2 internal case cylinder blocks. The shaft is held in place with a small bolt and a snap ring.
Of course, the safest thing is just to spend the $280 on a new compressor and not have to worry with it.
Hope this helps.
