Pinions aren't staying on motor pole
Hey all, So im having an issue that has recently occurred and I do not understand why its happening. My pinions will not stay on the motor pole. Is it possible for the pole have this happen? I have tried numerous pinions with numerous screws and once i start driving they just untighten and come off. I tighten the screw as much as can go so i just do not understand. It's a castle sct motor if that matters but I wasnt having any of these issues until recently. Any ideas?
thanks!
thanks!

Well I've been using robinson racing pinions which were working fine, also at one point I put on a traxxas one that also worked. Maybe I just need new grub screws could they be worn? Ive never used loctite before maybe that'll slove my issue.. is it just some kind of adhesive?
choppinwood, yea its metal to metal once the grub screw touches.
p.s Thanks for teaching me a new part. Didnt know grub screw had a special name like that.

as far as application goes, prior to putting the screw in, just put a small drop on the tip of the screw itself and then screw it in. let it sit for at least 24 hours to cure fully before you go run it!

BUT I also take the time to figure out where the grub sits on the motor shaft with the best mesh, then take the pinion back off and make a small groove with my dremel. Once you make this groove the grub will never slide anywhere.. a touch of thread locker and it's not moving anywhere. You don't need a big divit, just a small hit w/ the dremel and your good.

do yourself a favor and DO NOT buy loctite at the hobby shop. check your local auto parts store, you'll be able to get twice as much for half the cost.

thread locker is a must..

This is me and only me, I've never in 20 years needed or wanted to use Loctite on a pinion set screw. Are you using a QUALITY wrench to tighted it?

Brushless and lipo even if you were on the cutting edge is less than 10yrs into this market.. for most only about 6. I never put anything on my brushed motors either ;P never had a single pinion issue until the two forces met (lipo/brushless) and all of a sudden electric was faster than nitro. For me the first time I was in a race and had a DNF was the last time I didn't use thread locker
