I'll have to ask mistercrash. I ordered the exact part number he gave in his build thread.

EDIT: I'm almost positive it's the right gear (TRA3984X) but you just need to modify it quite a bit. The other gears can be used, probably with less or no mods even, but I'm following mistercrash's instructions exactly. There might be a reason he chose that gear instead of the other CD gear. Waiting to see what he says.

SC, I'm pretty sure it wont work, because Mc received all the info from me, considering I designed and built the first one. the reason it won't work is the teeth count s incorrect. So I'm just saying this is all. But you can wait for MC....

TRA3984X is the output gear that comes stock on the Forward Only Shaft in the ERevo's tranny. It has 33 teeth on it just like the output gear of the Traxxas CD. I used that gear because the output gear on the Traxxas CD is not sold separately. I found it was a lot of money to buy the whole Traxxas CD just to use the output gear so I modified the output gear TRA3984X instead. I am also working on fitting a different gear from Traxxas that has the same tooth count and that is inexpensive and may require less modifications.

OK good, just needed to make sure I had the right one. Be sure to let us know how that new gear works out.

Sorry for my miss understanding... let us know how it all works, also SC, sorry if I came off harsh......but sometimes it appears to me that when I put input into the discussion about this CD, it's like im treated like I dont the what the heck im talking about and that everyone is waiting for Mc to respond....

No big deal at all. I just needed to be absolutely sure before I sent back the gears I bought and ordered different ones.

sjcrss · 08.26.2009, 05:02 PM

no cause i have one

500k oil feels like it's empty!! the E-revo diffs in front/rear are able to be put up with, still 500k in the front diff is what's needed (5k in rear lol)

when i get hold of one i'm going with the hyper 7 diff mod.

Actually I think I'll ask mistercrash.... oops sorry...

All joking aside I'll definitely have some questions once all the parts show up and I start the build. Thanks for the help so far.

OK, I don't mean to be rude guys, but...........

9 Posts later and I'm going to ask again.

"So Can the Traxxas Center Diff hold up to the power of the Castle 2200kv Motor on 6S?"

Bondonutz · 08.26.2009, 10:55 PM

The gears are small just the the regular diff, set the slipper to your tatse and it'll last a while. You wanna use 6s with 1/10 scale diff,it's gonna give sooner or later ?
I was using one with nitro for a few months befor I decided to convert it, I checked the CD and gears were ok, but leaked dry. Leaking is problematic with the silicone gasket design. Sorry I can't be of more help..

How dare you ask us not to hijack your thread!!!!!!

Go for a hybrid CD if you are going to use one. From what I've read the Traxxas CD will unload way too much to the front, especially since you'll be running 2200kv on 6s. The hybrid CD will handle the power much better. The Traxxas CD may be able to handle the power you're going to give it, but I think you'll have a hard time getting it to function how you want.

Thanks Bondo. I appreciate it.

I just want to get this "pick list" of parts together.

My setup is going to use 4S actually.

A MMM ESC and a 36-70-2000kv Medusa. I may upgrade to a larger motor later. But first I have to get this setup to be reliable.

I'm not sure If I will like the handling changes the center diff brings, since I mainly bash. I may give it a try though.

PS.....I've been running the 1/8th scale RCM diffs. Kinda disappointed they didn't hold up longer

I take it that it comes with oil that is waaay too thin?

What do you suggest the diff be filled with? I could fill it with bearing grease or something really heavy. LOL

This might also help with the leaking problem.
