Tamiya gear diff orings ?

[Rich D]

What orings are you guys using in the tamiya gear diffs ? I built mine as per instructions with the std black orings and they seem to be weeping quite badly

Thanks !

I know its a dirty word, but you want to use Kyosho O-Rings.

I did a guide here. I have done this in my 501x (5.5t) and 417 (17.5) and they are smooth and leak free..

Still need to get some Kyosho ones as well.
Esp. the rear diff likes to eject 90% of the oil within a few packs.

Yep, Kyosho red - tried everything else, these actually work.

This info is greatly appreciated. Just got a 417, also rebuilding 501X (big pulleys) with gear diffs on the way..

Big thanks

Edit: where do I find the TDX AC16003 smart shim?? Any help would be great. Also, if I use the Tamiya shims how many per side with steel bevels?
