Kevin;

I’ve got a ’55 Chevy shop manual that has a few detailed photos of a generator rebuild. With respect to the question about the finish on the ‘end caps’, fan, and pulley . . . all of the photos indicate a low gloss black on those parts. The photos are surely a Delco unit, and I suspect independent of customer all of those units left the ‘generator factory’ with the same finish. All of the surfaces that come in contact with another component were unfinished allowing metal to metal contact . . . this is likely done for two reasons; 1.) Painted surface to painted surface will likely wear and the assembly loosen, 2.) Those interfaces are the means to complete the ground circuit and the paint would represent an insulation layer. That lack of paint includes the pads where the generator meets the bracketry. I’ve never seen the long thru bolts, or the oil cup painted.
