I recently brought my Uni I motor to be recoiled / rebuilt. It started to smoke and eventually burnt out.
The motor had previously been working and turning the cylinder (a bit slower than normal, but functioning).
I received a call from my machinist, who after taking it apart told me the internal gear had worn down as well. He said it needs replacement and would most likely seize up and re-damage the motor.
He sent me the attached photos.
I was curious if anyone has had any experience replacing this internal gear, and how/where I might go about procuring a new one.
Thanks in advance!
