New to me 6" X 48" belt sander/ 9" disc sander

I think we talked about capacitors and the inability to truly test them without load & thus its just simpler to buy a brand new one of the same type and see what happens.

Motor is 1.5hp. Unfortunate it is the same motor (just painted green by manufacturer - General) - https://www.kmstools.com/magnum-industrial-heavy-duty-belt-and-disc-sander-118951

Thus the motor has extra cast parts to accommodate the sand belt and the disc. The disc is somewhat easy as it is just a shaft but the belt is touch harder. This design is same as in a grinder where motor sits between two spinning grind wheels. If it was a belt driven design I probably would have already just replaced the motor with something else.

Gotcha. I should have read your original post better. I was going to give you my new motor but I think it is just a 1/4 HP furnace fan replacement motor with a common shaft for pulley. Hopefully the new cap solves your problem. Best of luck.
 
It may not be the start capacitor. It could be the centrifugal switch mechanism that engages/disengages the start cap circuit. If the start cap is left 'on' for extended duration it can/will degrade the cap & ultimately end with magic smoke show.
