BL Revo using Revo Transmission? - Page 10 - RC-Monster Forums

Well, I was at the track today and I once again broke one of the little pins that hold the gear to the shaft (internal to the tranny). Is there a stronger replacement for this? It's the pin in the lower right corner in the picture below (borrowed from buytraxxas.com).

Other than that, the tranny is holding up well. All the internal gears show little or no wear and the locking mechanism (v2) works well.

Brian, did you ever install the center diff?

Dang it! I knew I forgot something, and I just had the tranny apart too! :007: :007: :035:

Good point squee,
The center diff should releave some of those big bursts of stress on the tranny parts.

I agree on the center diff and relief of stress. It should make tranny last better.

The sad about this is that I got a custom center diff from Squee a while back (uses buggy diff), but keep forgetting to put it in everytime I have the tranny apart.

Put a yellow note on the gearbox..

It shouldn't take but about 20 minutes to do...If that.

BrianG · 11.25.2006, 03:55 PM

lol, yeah, or tie a string to my finger...

I know it doesn't take long, but I don't like to take things apart unless I need to as the threads get worn. Besides, I was just looking at the diagram that it came with and I think either something is missing or something doesn't fit quite right. I'll take a better look sometime...

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.

No pics of the diff in trannsy. Oh why?

squeeforever · 11.26.2006, 10:51 AM

Hmm...Sounds like a PITA...I never had any troubles at all...It went in as easy as possible...

Well, because I thought it's not really interesting. I mean, there are plenty pics of the Revo trannys around and only the diff was added. This allows you to use your imagination. :)

OK, everyone can use their imagination except Serum - and other like-minded sickos. :005:
