Motor Shaft problem
 

Myself and a friend are building each a car to run I have a Nue Motor and he has a Tekno square can motor, I run 5s buggy and his is a 6s truggy, I ran mine 3 races and love it, he just got his and I watched it run one lap just getting the brakes set, when he went to pull wide open the thing just stopped going, when we looked, the shaft was broken off inside the front bearing, are the long pinions to much weight for these motors.---Jerry

Sorry to hear about this. I don't think the pinions are the problem. We run heavier clutches on them that stick out even further and have yet to break a shaft. However, there were a batch of Neu motors that had some shaft issues. They were hardened too far and then were tempered down a bit to make them not as brittle. Do you have the build date on the motor? Go ahead and email it to us and we'll get it sorted out for you. Thanks.

I think he has already e-mailed Tekno, I know he will be treated right. Thanks---Jerry

I am Jerry's friend that had the problem. The date on the motor is 11/13/08
and I purchased it on 01/14/09.

How do I know the build date on the motor?
