We'd been planning on using the same system of retaining the pinions as on the kit transmissions. The team is a bit averse to using Loctite on anything because of the large amount of plastic we typically have on the machine. Instead, we use lock nuts.


What we did last year for holding the pinions on was file a small grove in the motor shaft and use an e-clip. Since you have a key way, and a setscrew it doesn't take much to hold the pinion on the motor shaft. The trick with this is to cut the grove to match a size of eclip.
