Kyosho Transmission ??s UPDATE: Cluster gear sol'n/Mod

[Mad Racer]

I'm pretty sure they are the same screws that are used to screw the old 3 part wheels together . Small self tappers.

I just don't know what size that is. I don't have any Kyosho cars for reference. I need them for a Bullet Power Glide belt drive for an RC10. It was based on the Ultima gear diff and uses the same screws, which I am missing.

Here is a shot of the Ultima differential assembly.

So here's a solution to the cluster gear for all other Ultima and Optima guys needing the gear...




Traxxas PN1884 from the hawk/sledgehammer/bullet. The gear takes (2) 5X11 bearings. It is a 44t main gear/20t secondary. This changes your ratio with the stock counter gear to 2.73. The gear comes with a tapped 5mm shaft, you just have to drill your motor plate a new hole ~.75 (maybe an extra .0625 or so mine meshed to tight.) from the center of the top shaft. You can also use the 26t counter from the Thorp OD set, and I don't think you'd have to drill a hole at all. That outside setup is 26/20 - 2.54 ratio.
