I'm looking at installing an AC compressor to use as an onboard air compressor. The compressor is a stock AC unit out of a "98 grand cherokee charged with Freon 134.
There are several good writeups on this but none of them address the compressor lubrication. I was under the impression these compressors were lubricated by the freon running through them. if that is the case, how do you keep them from burning out without some type of oiler on the intake side?
My rig had the jeep compressor running for years by just hooking the intake side to the crankcase breather, this grabs slightly oiled air. I hooked my gm one the same way and it's working so far. I would recommend a drain on your tank as it does get oil and water build up.
