A/C Compessor Rebuild
Actually more specifically reassemble than rebuild. I want to have the A/C compressor case on my 92 LT1 powder coated to match a few other pieces I've already had done, yea I know just bear with me. I would've thought given how hot the compressor becomes during operation it could handle the powder coating baking process. However after talking it over with my coater we decided some of the seals probably wouldn't survive. Well I feel comfortable pulling it apart, the GM service manuals seem to be detailed enough. But, as with things of my grandmother's I pulled apart as a youth, I'm a bit un-confident in getting it all back together, not to mention I have no way of really bench-checking it. I have a brand new (read rebuilt) unit I want to do this to. If anyone knows of a shop or someone who could reassemble and test my compressor please hit me up with an e-mail, PM, or here.
Thanks in advance for the help....

The guys at www.ackits.com may be able to help you, but I'm not so sure that they rebuild in house. Actually, the only problem you might encounter (besides getting coating on the inside) is reseating a new shaft seal, though using a socket of the same size with a rubber mallet works for me. Once you get it back together flush it with fresh oil (compatible with whatever gas you're going to use). Add four ounces and turn the shaft a dozen or so times in one direction, then the other; drain and repeat leaving 3 or 4 ozs in it. As an alternative to coating (and with less risk of getting something on the inside - assuming it's apart), you could just polish the case and clearcoat it.

Hey Sun,
Thanks for the reply, from your post I gather you've had this style compressor apart before? If so do you have any additional tips? Would I need a puller do take it apart? FYI, the clutch is not installed (I have a new one for it). Looking at the case and service manual it looks pretty straight forward. I figure if I take my time and carefully note how it comes apart I should be able to reverse the process. Do I sound convincing? lol You know there is actually a guy down in Kansas City who does incredible polishing, problem is I'm just not a chrome/polish guy. I prefer a clean factory look with a little color. I know I want 39 cent gasoline to. The guy who would do the coating does incredible work, I'm not worried about the powder coat getting into any where it shouldn't. Thanks again for the tips and hope you can pass on any more.

No - I've never taken one completely apart. If it's seized there's nothing to fix, so beyond shaft seal repair - which involves removing the front cover - I've never had reason to pull the pistons or shaft. This Link wasn't working the other day, but maybe it's back up: http://www.pelicanparts.com/techarti...so_rebuild.htm It's a different model Nippo but the procedure is the same and the owner went through a lot more than what's usually necessary. Also, I've never been able to locate tolerances or replacement #'s for the shaft, cylinders or even the cases. About the best you can find is maybe a new snout and manifold plus the seals.
