What color lock-tire do you use? Blue has always worked for me, but I also make sure my allen wrenches have a nice (non-rounded) tip...

I had this one grub screw that kept coming loose so I tried filing the grub screw flat which ended up making a difference. That way you have more surface area on the flat spot.

Okay guys - got a followup for ya...

Is it "bad" to have a setup where the pinion is mounted so that the gears are closer to the motor and the grub screw pointed away...? Does it matter..?

I've done both and never had any issues..

Most of my pinions are this way...I've never had a problem.

My Finals aren't until January...in HS, the week before winter break is just kind of "lull" week, cause most teachers have given up instructing anything cause everyone is so excited.

It really depends on what your running the car on. (under race conditions) ive spun pinions off my motor on clay tracks but ive had good luck with them staying on on loose loomy dirt also... But i eventually ended up grinding a flat spot on my motor because its one less thing i have to worry about over a 25 min main.

I think this guy needs some reassurance! You can do it. You can't hurt your pretty motor. Grind away! If you're afraid of removing too much (you can't unless you remove half or more) align your gears, figure out where the grub screw will hit, and only grind there. It only takes a little flat spot. if you're scared use a file, I wack mine with a cutoff wheel and a dremel, you're making it way more difficult than it is. Get flatspotted!

You guys were right. After about 12 runs I just lost my pinion. Thankfully it did not damage my spur and I found it. Now it is just a matter of a little dremeling.
