I recently acquired a model 22272, chestnut brown 52" 2-speed non-reversible motor that was stored in a cellar for some time. It has a few small rust spots but nothing alarming.
I happened to stick a piece of masking tape on the cast iron case the other day, and when I removed it, small flakes of paint came off with the tape, leaving behind spots of bare cast iron but no rust. I experimented by sticking tape on other parts of the motor body and then pulling it off, and same thing. But the paint on the oil cup/switch housing seems fast; not a trace came off with the tape test. Apparently the paint is adhering poorly to the iron parts cast in a sand mould.
I was already considering repainting the motor since brown doesn't go very well with the decorating scheme in the room where I plan to hang the fan, but now I'm pretty sure I'll have to follow through with the repaint job. I had planned to apply a chemical deglosser over the original paint and allow that paint to serve as a primer coat, but now it looks like I'll need to strip the entire motor down to bare metal and apply a fresh coat of primer before applying the top coat. There is no sign of any primer coat under the original paint; the coat is very thin, and I can scratch it off and expose bare metal with my fingernail.
I never particularly liked the chestnut brown finish anyway, which looks to me like ugly metal primer lacking a top coat. I just wish it adhered better to the metal so I could simply paint over it.
I don't know if this is typical with this particular paint, or if the moist environment may have softened the finish, but I would think if that were the case, there would be some rust on the metal surface underneath.
