Am not aware that they are serviced in the aftermarket.Not much to go wrong with them. Classic auto air or whatever they are calling themselves or rebuild division used to rebuild them but you had to ask special to have them plated zinc silver. They painted them black otherwise. I have had a few plated locally but it has been years. I have been lucky find finding NOS units.

I've heard that yellow cad will "wash off" leaving the silver only?

The only thing that is gold in this case is the bolt and washer holding the clutch to the shaft of compressor and maybe the bolts holding the field coil to the Compressor. The clutch and field coil are silver.
