After the balance wheel is removed, taking off the motor is relatively easy. You only have to remove 2 screws that attach the back of the gear housing to the head of the machine. Then you just pull the motor from the head, with a little wiggling if needed.
Here she is without her motor. You can see the two screw holes on either side of the gear shaft.
Front and back views of the motor after removal and close-up of the wiring
As you can see from the close-up, the wire covering is completely shot. It should be interesting to see what the wiring looks like inside the motor (shudder). I guess I’ll find out soon!
