What brand pinion works for Rlaarlo spur?

[dure16]

All of my mod 1 pinions are too wide to use as a spur gear on my Rlaarlo 917.

Where can I find pinion gears that are narrow enough to fit?

What do ya mean? Wide enough you can't tighten the grub on the shaft?

@LibertyMKiii has a good explanation of the Mod-1 conversion.

There’s not much space on the shaft for the pinion to fit between rear diff and motor mount. The combined width of the pinion’s teeth and shoulder is too wide.

I think saga pinions are narrower and might work. Hoping to hear from someone who already figured it out.

I ended up finding that power hobby gears fit a little better than Saga. Also flipping the gear so that its open face fits over the diff housing added another mm or two.
I think that required extending the flat spot on the shaft or making a new one. I sold the car and don't remember now...

Perfect. Thank you.
