*HELP* Pinion Gear is not centered

[Mother_Trucker]

Hi guys, I need some advise with this. I have a brand new Castle motor and esc. When I installed it into my truck I noticed it the tires jammed when I tried to roll it. I couldnt figure out the issue until I examined the pinion gear and realized it's not centered on the pole of the motor correctly. When I tighten the screw it clearly pushes the gear to one side, I can't imagine this company would design something with this big of a design flaw. Here's some pics attached. Am I supposed to put something else in the pinion gear so this doesn't happen?

Now that I'm looking at it, I'm starting to wonder if the pinion gear that came with the truck is designed for a different motor altogether?

I think you've got an 8mm bore pinion on a 5mm shaft. Regardless of size, the bore is too big.

You are going to need to post the specifics. What castle motor and what pinion is that?

In all honesty this is for the new Losi LMT truck, it came with a pinion though I don't know the exact specifics I looked at some online and it seems to be one with these specifics 14T 1.5M 8mm Shaft. The motor is a Castle Creations 1/10 Sidewinder 3800kv sensored motor. I'm starting to think it may be too small for the truck. What options do I have here?

The bore is WAY TOO BIG. 5mm shaft with an 8mm bore as said above!!

It is a 5mm shaft. Try and Arrma 3s or 6s pinion on there JUST to TEST the shaft size

I'll have to try that. I'm gonna have to take it off my Arrma Granite which I don't want to do but just to try it out. I got some Traxxas pinion's that I could also use as I don't run those cars anymore.

Thank you for the help guys, great customer support in this forum lol. Figured out the issue within minutes.

Use the TRX ones. Don't take the ones out of the Granite. You are likely to strip unless you use heat since they use red Loctite in there.

Doesn't the Arrma Granite BLX 3S come with an extra pinion? If so I may have one I just gotta find where I put the bag that came with it.
