I have a Tamiya #97 gearbox with upgraded Solarbotics RM3 motors and I need to replace one of the pinions as it appears to have cracked.
This project is from 2009.
The pinion gears I used on the motors are the one from the Tamiya Gearbox. They have no untoothed collar part, and are 100% toothed. They are in the photo on the #97 box.
I have a second set of RM3 motors from the 2009 order and the pinions included there are not the same because they have an untoothed collar part.
Is there a way I can order more pinions for the Tamiya #97 gearbox? I see the who assembly is on sale right now anyway, but if I could just get the pinion to repair the project it would be great. If I can’t get it from Pololu, I don’t know the specifications so I don’t know what to order from a small parts site.
