RV2 AC compressor Rebuild help

The compressor case on the right is an older part number going back to the late 50's early 60's. The V piston compressors had a long life span from the late 50's to pick up trucks in the early 80's. The RV-2 part numbers I listed are from a 70-71 parts book as that is the age of my 71 Charger. The last pick up truck compressors may have been the smaller displacement compressors because truck cabs are small and don't need the cooling capacity of a big Chrysler. The piston package you show is a late 70's piece and i don't really know anything about the last of the V piston compressors from that era. My earlier posting was just a heads up that not all V compressors are RV-2's and changes happened along their life span. I think your approach of rebuilding your own compressor is a good one because it's very difficult to find a quality rebuilt RV-2 today. None of the commercial rebuilders seem to care about this old stuff today as the market is so small.

I know what you mean, I purchased two reman units from ebay and both were trash when I received them. They were a spray paint black reman special.

So the only thing I will be changing in the compressor is the crank with the smaller bearing, and new gaskets I will reuse the pistons since the new ones are for late RV2s.

The compressor that you said is on the right that is from the late 50s and 60s was the original one on my 73 Valiant when I purchased it meaning it was replaced at one point. Other than the bearing size on the one on the right the compressor should still function the same?

Thanks for all the info!
