Shopping for an AC compressor
« on: November 25, 2016, 10:57:50 AM »
The York AC compressor on my '67 Mustang isn't working (tech says no pressure on the high side).  The car had been in storage for years and now it's back on the road and generally running well.  Can AC compressors be rebuilt?  (I notice NPD sells a gasket kit).  Otherwise, I see several Mustang parts vendors sell new York compressors and that may be a better way to go.

Compressor can be rebuilt.  Try Classic Auto Air - used to be pretty reasonable.  The newer York compressors have a different casting for the head than the vintage ones - and maybe other differences as well.

There's not much to rebuilding one. A simple piston design, a shaft seal, a magnetic clutch and two check valves built in the compressor head. The piston and rod portion virtually never fails. The shaft seal occasionally leaks so ought to be changed. The compressor clutch and magnetic coil is available as a service part and a gasket kit with the check valves is available usually in a rebuild kit. Pull the plug on the top or bottom and chainge the oil, especially if you are going to use modern refrigerants.

After additional research, I'm informed that the AC compressor on this 67 C Code car must have been replaced at least once, since the one installed on the car now has a York flange-style fitting configuration on the cylinder head, as opposed to the correct Rotolock fittings that were original equipment.  (Or maybe only the head and valves were swapped at some point).  Anyway, I'm leaning toward a new York Rotolock compressor instead of trying to rebuild the compressor currently on the car.
