Want to get Titanium pinion gears... aluminum is too soft for me... i have stripped the threads on the grub screw hole many times when moving my pinion gears around... (i try to make sure i screw and unscrew at a 90 degree angle... but it hasn't done me any good)...

so any suggestions where I can get a good set of Ti pinion gears? I want to be running 19T, on a EVO V...

If you need additional info, i will be glad to post some.

dumb question....what kind of tool are you using to tighten and un-tighten the set screw?

I ask because early on when I was first into racing I only used the little allen wrenches that were right angled and I used to strip the female threads of pinion gears. But when I switched over to wrenches that had handles like the Losi tools and the Dynamite tools I never stripped another pinion again.

just a thought.

Oh yeah, I also went to using thread lock and that too might help.....

I am using Hudy hex wrenches... so i think maybe there is something wrong w/ the way i use them ... or something... i just can't figure it out

baih

it sounds like you are overtightening the setscrew. are you using robinson pinion gears. are you using blue locktite on the setscrews

another thought....is the motor in your hand with the pinion gear attached to the shaft when you put the set screw in then tighten it? If you are waiting to place the pinion on then the screw, once the motor is mounted in your vehicle you might be attacking the screw, with your wrench, at some funky angle causing crossthreading or as baih just mentioned.....are you getting the screw in correctly but tightening the crap out of it causing it to strip.

Seems there's three ways to ruin the threads and/or the female hex area in the screws....crossthreading ,overtightening and using the wrong size wrench for the job.

I think I use a standard 1/16th wrench for all my pinion screws. I'm using Trinity, and Robinson pinions. My Tamiya uses a different size wrench, and a different pinion manufacturer though.

Perhaps i end up cross threading... i run a tamiya ta04-trf.... the thing about it... is that i must mount the motor before i screw the pinion on...

I am not sure what pinion gears i am using.. all i know is that they are 64p ...

A friend gave them to me when he quit racing ...

I use a 1.5mm hudy hex to screw my pinion in... so i htink i am not aligning my pinions right....

i tried before to not over tighten them... but in that case... i end up with a loose pinion...

try using a little teeny tiny amount of thread lock, the blue stuff.

put the screw into the pinion first, before mounting it to the motor, back it out enough to just allowing mounting to the shaft, then tighten it down, You don't have to moose the thing with 15 lbs of brute force. Feel when the screw meets the shaft then just go another 1/8th of turn.

I also agree about the site navigation, their site can be a nightmare.

thx! i just realized i spelt "sight" wrong... sigh... embarassing....

8 pinions for 40 USD... that's not too bad...

yokomo has very nice pinions, they are a little more money but super smooth and quiet go to the yok site, click on parts list, pinions start with part number PG. 48 and 64 pitch
