Trying to get my first sprocket squirrel cage off the drive motor shaft. Read everything and still stuck after 5 hours of trying. Finally got the bearing plate off after 2 hours of prying and pulling. I imagine if that was stuck on so incredibly tight I'm in deep. Lots of heat has been applied. I'll reseal the motor after. Cold chisels have not budged the sprocket after a couple hours of heat, banging and prying. The puller tool is stripped in the sprocket and not unthreading. Just spins in the sprocket threads. Anyone have any ideas? I'm willing to buy any new parts to replace the old ones, just want to get this thing apart. Very frustrating.
