Default Leaking Differentials

impalabob,

Since you just did your build, did you have any issues with your diffs leaking?

I noticed diff fluid accumulating on both front and back belts, so I ordered some new O-rings and rebuilt the diffs and that seems to have fixed it.

Looking at the design, it’s easy to not get the O-rings in the right position, and easy to mix them up. Good thing Kyosho still supports parts for this car.

Another question: how much axial play does your clutch bell have? The spec shows that there should be some. Design-wise, any thoughts on why Kyosho wants axial play on the bell? I’d think there shouldn’t be any at all, and that the play would delay engagement of the clutch.

Thanks,
jcalchi
