I'm working with a few old motors trying to find one that I can retrofit to work with a bandsaw I recently picked up. I have identified a repulsion start induction run motor that I can reverse rotational direction on (it's currently turning the wrong direction), but when I took it apart to check the bearings for wear, etc. (it had been sitting outside in the elements for some time and the lube sumps were completely dry) I found that for some reason the rotor cooling fan is spinning freely on the shaft. It appears to have had a shouldered bushing pressed onto the shaft, followed by the stamped aluminum fan, then a pressed on collar.
I'm having a bit of difficulty setting the collar tighter so that the fan actually rotates with the shaft, so I'm looking for some suggestions.
