    If you have ever had a Sunbeam clock or a Mastercrafters clock with a Sunbeam movement in it, you have probably had a problem with the little orange/red gear in them disintegrating. Here is a way to fix these movements by replacing the gear.

    You will need to remove the three screws to open the movement.

    You need to now remove the rotor. (The black magnetic disk in the lower left corner)

    You now can put your small, ten-tooth gear on the rotor.

    Now you can clean and lubricate the small plastic pivots with a light grease. (I usually us white lithium grease.) Now you can assemble it and make sure that the stopper is in the right way or the clock will run backwards/not at all.

    Now test the movement to make sure it is working okay.

    Now you can put your clock back together and test it.

    Your clock should now work for a long time to come. :excited:

    Thanks for sharing your Sunbeam motor fix. Where did you obtain the replacement 10 tooth gear?

    That is the tricky part, I usually find them in cheap quartz clocks, but it depends on the design. The one i used in this fix was from a small appliance timer.

    OK I'll look for a suitable gear on some scrap quartz movements.

    I am trying to make the gears out of rubber, and it seems to be working.

    The rubber failed, but I have found a place to buy the gears for pretty cheap. I completely forgot to add this note.
