                  Look at yours.  If it looks even remotely similar, it will fit.

When replacing the motor, you should also replace the copper clutch spring. The clutch spring is press-mounted to the center shaft. This bond breaks. If it slips, the clock will still lose time. We always change both parts at the same time our shop.

Tools needed: 
1) A small flat blade screwdriver
2) A medium (#2) Philips Head screwdriver
3) A magnet to magnetize the screwdrivers (optional)

To begin: Unplug the machine

  • Remove the cover, using a magnetized flat blade screwdriver
  • Pop off the “C“ clip that holds the movement on. 
    - Watch your fingers, and watch that clip fly across the room.... 
    - It's at the upper left of the frame. 
  • Remove the movement.  This exposes the motor.
  • Back the two motor screws off, about 3 complete turns.
  • Remove the wires that attach the motor to the wire block.
  • Jiggle the motor out, then move the mounting bracket over to the new motor and spring.
  • Reinstall:  Do the reverse of the above.

Since it's already all apart, this would be a good time to oil the main shaft on the movement, and to change the ribbon.  Use a few drops of WD-40 on the moving parts.
