How to remove riveted motor nameplate?
I am working on a late 1950's Kenmore 158.371. The motor lets out a puff of smoke whenever I start sewing. I have not over-oiled it. I can't tell if it keeps smoking once up to speed because the air flow the motor produces at that speed blends the smoke into the flow to make it invisible. I would like to open up the motor to see if I can find anything wrong, but the motor name plate is riveted to both halves of the motor case across the seam of the case. I've seen other motors where the name plate was screwed on, or one side of the plate was slotted so the plate could be slipped off on the slotted side. Does anyone have experience with this? I can cut the rivet or pry the plate loose, but I don't want to damage anything if I don't have to. Also, any advise on the puff of smoke is appreciated. Thank you!
