Kyosho Ultima Ball diff???

Quote

Post by Mad Racer » Sun May 23, 2010 10:38 am

I have just rebuilt my ball diff that came in my Ultima.

To my surprise this ball diff is so crude in its design. Has no polished drive rings and no thrust bearings just rides on washes.

Is this right or have i got a dud diff.

Thank you.

There should be small 1.5mm thrust balls, 5 i think, between 2 thicker washers plus the bellville (spring) washers. If there aren't any balls in there that it won't work. Fine for a shelfer though

Just rebuilt the ball diff with WBD-4 pressure plates and it seems these make the diff too wide for the gear box. Any advice on how to make this work? Doesnt look like there is much I can outside of machining the stock pressure plates down a bit to...

WBD-5 is the new part it has the spring and T-nut and using WBD-4 plates and it does fit the ultima balldiff.

I'm about to rebuild a turbo Ultima and I noticed that in the manual there is no clear indication on how to build the ball diff. There's an exploded view but no instructions... :!: like say in a RC10 manual. I'm wondering expecially about how to...

Wow, that's the old instruction sheet!
Well I did not remember the total count of conical washers, and it doesn't really make a difference to stack the conical washers pairs all on one side or half and half.
The most important things are to put the...

Looking for details and options for the Triumph ball diff rebuild.

The Acer ceramic balls look like a cheap and better alternative to the Kyosho LA-4 and WBD-6 balls.

I believe the diff balls are 3/32, correct?

Does anyone have the size for the...

Does Kyosho part WBD-5 (ball diff shaft set) contain the needed parts to rebuild the diff? I haven't been able to find a good description of the parts bag and can't find a picture that clearly shows the contents. I'm curious if it contains the diff...

I posted a couple years ago about having some issues with my RC10GT that I converted to brushless. It just would not put the power down. I drive mostly on the street just fooling around and that ball diff would inevitably chirp and get gritty after...

Nice! U need to start doing videos on youtube like johnnyq90

Definitely thought about it, but when it comes time to do stuff I just want to get it done and not worry about camera position, lighting, etc. It can easily double the time it takes to...

Ok i Know a Ball diff is great and is standard on the top line kits.

I have been racing since 85 when ball diffs were very limited to the best of the best as standard equipment.

I have been asking myself this question for a while now based on...

I think it also depends on how technical the track is. The gear diff is heavier which means more rotational mass. People spend quite a bit of money to lighten every part of the drivetrain. If you need a lot of quick throttle commands a gear diff...

So I've got an RC10GT with a stock ball diff. For some reason I've had bad luck with this diff over the years. It seems to slip under brushless power, and when I tighten it down to the point of not slipping, it gets crunchy fast and breaks the diff...

Dang I’m running a 4.5t Novak Velociti brushless on my stealth 2:25 with a fixed gear hub, am I on borrowed time with my RC10DS?

Runs great and super smooth.

Using the proper grease in a ball diff is the most crucial part to making them live. If you just use normal grease even when cranked will still slip.

Proper diff grease isn't slippery as it's designed to let the balls bite into the ring and not...
