Are the bearings 9832 that house the diffs in the transmission case different if I wanna use the gear diff? I had a really hard time getting the gear diffs to sit in the bearings. I had to use a mallet to hammer the diff in.

YES, THEY ARE DIFFERENT!!! The gear dif from the rtr or sc10 use standard bearings on the gear dif outdrives, while the ft, worlds, or .2 use metric bearings on the ball dif outdrives. The case is also different because of this.

I took my ball diff a part and it was nasty dirty in side the case is this normal? I did not think it would get that dirty. Wow b4. 1.

im about to put Kyosho Big Bores on my original FT B4 and im trying to get some help with getting a similar amount of pack/dampening as my current setup. currently im running 30wt #2 pistons and black BB springs front with 25wt #2 pistons and white BB springs rear. i was considering going to #3 pistons front to get a bit more pack but im not sure if i want to do that yet.

My $0.02, if you dont already have the Kyoshos buy the AE big bores instead support for tunning is much more readily available. Dont get me wrong I have both and the Kyoshos are sweet but the AE's are a close second.

Why did AE go with big bores?When the 22 buggy hit the race circuits was it killing the b4's? I don't race as much as some folks anymore so I'm little out of date.In other words what's up with the big bore's?

best regards

im going with the Kyos because im getting a sick deal on a set unbuilt but with opened packages. otherwise i would be going AE. a few local guys run Kyos so i can get setups from them but i figured until then i can try and get a comparable setup to what i have now.

I have never had dirt in my tranny or diff. So yeah, that is weird. did oyu buy the kit new?

I wonder if he has the wrong outdrive matched the to the wrong bearing too? That would allow enough of a gap between the bearing and outdrive to get dirt inside the transmission and make a mess in there. Why in the world did AE make that change? It was just asking for this to happen repeatedly.

Oh forgot to mention mine is a b4.1.

You can use AE BB pistons in the Kyosho shocks no problem A 1.6 piston will be similar to the #2s you are running now. You can also check AE's website for the latest setups and you'll be good to go.

Maybe you guys are confusing dirty with dirt. It is possible that his diff once taken apart is dirty...thats fairly normal. Now if there is actual dirt inside the diff, then he has an issue.

The gear dif uses a different case & out drive bearings the the ball dif. If you started with an RTR it came with a gear dif & would need a new case & bearings to run the ball dif. If you started with a FT or worlds it came with a ball dif & would need a new case & bearings to run the gear dif.

Go to rc10.com & pull the manual for the b4.1 RTR & the b4.1 ft or worlds & compare part #'s for the case & out drive bearings.

Ahhh crap... Gotta buy more stuff now.
Thanks for the help.

Yes new b4.1 wc.the case was dusty in side but the diff looked ok just dusty. I guess. But I clean it all out and rebuild the diff
