I am trying to rebuild a generator for my 1928. It has a long nose generator on it now. I put on a fan shroud to help keep the engine cool. The current generator pulley walks ahead enough to rub the shroud while driving it. There is almost no clearance with the engine not running.

I have 2 short nose generators that that match. I was hoping to use the best of both generators to make 1 good one. I have already ordered the needed parts. The one generator has a newer armature, brushes and fields in it. Who ever rebuilt it way back when ran the two wires out to the cutout and ground and epoxied the wires in the terminal hole. The weld on the case is rough and looks terrible. The other looks dirty inside but the case is much nicer, not pitted and the weld is hard to see.

The 2 generators I have to use have different size pulleys. One pulley is about 3-1/8" diameter the other is about 3-1/2' diameter. Both will fit either armature ok. Which pulley would be the best to use?

Thanks for any advise.
