So I took apart the GE 12 inch strap F15s125 fan. I blew out the inside of the case with compressed air to get out the loose dust. There was a crack I found in the main case and so sanded the inside and put JB weld on it with rubber bands to hold it in place till set. I have used this to repair several bakealite  clock frames on GE clocks. There does not seem to be any real stress on this area so it should hold fine. I am letting oil drip into the main motor hub and its nice an loose. The only thing I am a bit concerned about is the hub where it connects to the fan blade. It was not on real tight. Tight enough to work OK but I just pulled it off took out the screws of the fan housing and it was off. No keeper I can find. I can drill a small hole and put a cotter pin in it. But I don't want to do this unless there are no other alternatives. Was this just a pressure fit blade?

Hi Ed, that motor casing should gently slide back, exposing the oscillator gear box cover. Watch the wiring as it will slide back thru the windings as you do so. Remove the 3 screws on top and open the gear box. You should clean and re-grease it. Also, the blade is pressure fit with a rubber grommet. Should be in the center of the hub on the blade and will slide on the shaft. I use WD40 on it and does a good job reconditioning the rubber.
