Using Tetrix Motors WITHOUT gearbox

The gear box on one of our Tetrix motors failed. Since using the motor without the gear box is legal and more efficient, we are looking into using the motors sans gear box.

Has anyone come up with a good way to integrate the little gear on the motor with the other Tetrix gears?

Is grinding down or otherwise modifying the gear on the motor itself allowed or would this be illegal motor modification?


The GDC has said that the gearbox is not integral to the motor, so modify away to your heart’s content!

I know, thats why I’m wondering how other teams have been using the motors without the gearbox.

I would take a small piece of surgical tubing and stuff it over the pinion, and use that to contact the pole directly.
