Damn Set Screws!!!!

[RCDad]

Lately I've had so many problems with the pinion gear set screw. The thing is so tiny and so easy to strip the allen hole out. Today I bought a new bag, put a new one in my TC3, went out with a need for speed and *whiiiiirrrrr* the set screw came out.

I don't know why they don't thread the shafts of electric motors like a nitrol

This will keep them from coming out. Just put them on your allen key so they stay on, then dab a little Locktite(blue) on there.

But thats to simple, I need it to be complicated

Yep, loctite seems appropriate.

Locktite is definately the way to go on all metal-to-metal threads. And silicone glue works great on metal-to-plastic threads, even though its glue, it makes the screw easy to get out, but it wont vibrate out.

If you want to complicate it, then use red loctite. The complicated part will come when you try and take it off.

And you thought going electric was going to solve all your problems

Why don't you drill it out before putting in a set screw and tap to a larger bolt? I do that on some of my stuff just to avoid that headache.

Also make sure that when you are attaching your pinion, you make sure that the set screw is being set over the flat part of the output shaft on the motor. If it's on the rounded part, it's gonna slip. BTW, I don't use loctite on my pinions because during the day, as my foams get smaller, I need to replace the pinion with a tooth or two higher to compensate for the smaller diameter of the foam. I only lost my pinion when I didn't make sure the set screw is hitting the flat spot of the output shaft.

That's exactly what I was thinking. I don't know why they had to make these so small.

 

[olds97_lss]

Probably because these are intended for small people... I had to buy a drill with a clutch in order to stop stripping screws on all my vehicles. It doesn't matter how gentle I try to be, when using hand tools, I break off or strip at least one bolt every sitting. Now my 12 volt drill is my best friend.

Same here! I'm always wondering where the fine line is between tightening to the point of damage or leaving it too loose and then it falls out.

I bought a set of losi wrenches that make things easier. I take the bit out and put it in my drill to install everything, then I put the bit back into the losi handle to cinch everything down.

Losi designed the wrenches so that the handle got smaller with the bit. It's a bitch on arthritic hands, but for cinching things down, it saves stripping screws quite a bit.
