Does anyone know if the b4 spur gears fit as a direct replacement? I am trying to gear the car down but the smallest pinion that fits with the standard spur is 20tooth so looking at larger spur as an alternative. Also how expensive are the slipper pads!!!! :o
Any help appreciated :)

B4 spur gears and slipper pads are a direct fit for the B-Max2. For the B-Max4, slipper pads are a direct replacement, but spur gears are different as their centre hole is bigger.

Thanks. I knew the 4wd spurs were different.
First time yokomo owner and absolutely love it!!
:drool:

Does anybody else think that the steering rack is weak? It seems really thin.

Not really....it does not stand out to me as a weak point...I quess time will tell!!:lol:

I think it should be fine. It's well protected and you have your servo saver.

Didn't experience any problems in one season of racing.

I didn't put the saver on! :cry:

Servo saver isn't needed. You have the flex of the plastic parts to give forgiveness. I've not run a saver in over 2 years and not done a servo.

Personally I just see it as another point of failure

Hi I have a rb6 but am nor getting on with it has any one here changed from the rb6 to the yokomo if so what do you think worth the change or not

Still building the bmax 2 MR can someone tell me what pitch the kit spur is is 48d.p or module 0.8?
Diff went together well but what balls are used in diff steel or carbide.

The instruction don't tell you to lubricate the gears in this correct?
I used finish line X-country dry oil on them will this be okay?
Threading the ball joints was eas,y too easy compared to other kits do they pop off? or strip the thread?#Just have to build theshocks do you use green slime on the o-rings?

I found the front camber links kept moving drastically after each run, as a quick fix at a meeting I put on associated turnbuckles with rpm cups. Has not moved since.

Also I didnt put any oil/grease on the gearbox internals as per the manual. It runs so quiet. And I used green slime on the shock orings

48pitch and the balls are tungsten covered carbide.

My new diff doesn't have any balls at all! :p

hee hee
my gear diff has been working a treat on carpet no balls for me too

what the parts no for the gear diff

B2-500GS

My gear diff ate itself inside lol.

Gonna back to ball diff and found it quicker anyway

Steve what wt oil were you running when she poped .. running 3000 at the mo

ANY ONE FROM THE MB MODELS / YOKO POSSY GOING TO THE LAST SILVERSTONE ROUND ON THE 9th ... would be great to put names to faces
cheers lee

I had issues with the gear diff though. Even without oil it was way too tight, felt like 50k oil so I removed the tiny shim under the pins. Fixed the tightness but may have caused the gears to eat themselves.

I think the issue is the casing being slightly too large making the outlive tight. A better solution may have been to shave half a mm off the outside casing where it meets the outdrive
