After quite a bit of CAD work and a lot of trial-and-error I have managed to create fully functional 3D printed replacements for the notorious nylon motor pinions which always disintegrate in Sunbeam electric movements. Along the way I also created replacements for the motor bushings and minute wheel, parts which also seem to fail occasionally on these movements.
I have written up an article which details how I created these parts and describes how to rebuild these movements on my website dasarodesigns.com. It includes links to order the 3D printed replacement parts directly from Shapeways. I hope that this helps keep a few more of these rather cool, if underappreciated, movements alive.
