BL Revo using Revo Transmission?

[BrianG]

OK, I decided to disassemble the tranny and install that custom center diff. Wow, what a PITA!!!

I slapped 'er in per the instructions and as soon as I assembled it, there was binding somewhere. Loosening the tranny case screws half a turn fixed it, but that was not a viable option.

I took it back apart and saw that the shim that goes on the gear side of the diff was bent due to some raised areas on the blue gear. So, I shaved off the little lumps on the gear so the surface was flat. Then, I put the Al shim on my vice and hammered it flat again. Of course, being aluminum, this spread out the shim so I had to do some precision dremelling (is that even a word?) to get the shim back into the right shape.

About an hour and a half later, and re-arranging the various thickness shims around, the center diff is installed and turns freely without binding or front to back movement. Obviously, I have yet to try it in real-world conditions, but I expect to be pleased since it's a modified buggy diff.
