I'm going to order a 6 tooth pinion gear from rc4wd in a few minutes but wanted to know how to make it fit in my king hauler? the factory pinion almost makes the motor hit the transmission and i know a 6 tooth will hit causing the gears not to touch? can some post a picture for me or a link to where i can see how to install this properly? thank you

I have six tooth pinion fitted to three of my rigs so far. I have no photos, but I'll explain as best as I can. Where the motor is mounted, this can be adjusted. You need to dremel or file, so the motor/ pinion can be lowered to mesh onto the large gear. Then you have to fit a spacer between the motor and the plate. It's a bit fidgety but worth it. Nice and slow, lots of torque. Ps: I still some testing to do.. So let us know how you get on.

The short one, is what is required. The spacer allows the teeth to mesh when lowered. You can use the bronze bearings (small ones) or a number of the cardboard ones that comes with the motors, I made about six. I am almost sure there is a thread on the forum somewhere, by Tamiya cowboy, I got all the input i needed from him.

Ps: I had a few spacers made since. If your in the UK send me your addy, I'll send you one for free.
