What size bearings are in the blowers for this transmitter? The model is Centrimax CXH33A33C 220V. I had one guy tell me that they were standard alternator bearing size...is this true?

I don't have the number off hand but I have indeed used auto parts store bearings for those blowers and they are very common. The EG&G Rotron blowers that Sparta and McMartin used were the same bearings as I recall and they are also the same bearing for my BoatFloater boat lift blower.

They usually have the number stamped on the bearing itself but even without the number they are easy to match. They crossed to a late '70s / early '80s GM alternator I think.
