Grinding Down Drill Motor Gears

How do you grind down drill motor gears? Is this an safe thing to do? We don’t need the gear but we want to use the motor.


I wouldn’t recommend it.

I don’t know if it is safe or not, but we have done ot with excellent results. Other teams say they have not had such sucess though. I don’t remember exactly what we did, but i can ask the kid who did it.

We press them off using an arbor press and two 1/4 in steel plates that we have milled down a sort of pocket into right at the crack between the plates – they kind of fit like a collar around the shaft between the motor housing and the gear.

Works great.
