Ran the B-Max (the cheap one...) for the first time indoors and the diffs now feel rough as hell !
Are the balls in the diffs cheap as chips ones, and will they be shot ? Can I use balls from elsewhere (any recommendations) as the Yokomo ones look very expensive. |

Sounds a bit strange?
Anyway I used Edit diff balls in my old B max they are about £10 per pack I'd check out the Vampire ones from Dms too as they are a good price |

the problem will be the trust plates .
have a look at them they will be heave damigd . and that hapens very quikly if it is set verry ticht . the rest of the dif is verry good and works perfect if U chage the trust bearing.

I know the standard diff balls are steel not carbide and wear very quickly,
AE or losi ones are the same size and last ages, as pointed out the thrust assembly could be a problem as well, but by just changing the diff balls and plates you will see a big difference. Peter |

The large diff balls are the same size as AE balls (3/32), but the thrust balls aren't the same (1/16). As stated above, they are regular steel and will wear faster. Especially if: 1- You didn't break in your diffs before your first run with them, 2- You didn't surface your diff rings 3- You overtightenend your diffs or 4- You ran the diffs too loose. I believe #3 and 4 are the major diff killers...
I used Yokomo Tungsten carbide balls to rebuild the diffs (a pack of 12x 3/32 was 11$ US I believe) both for the diff ring balls as well as the Thrust bearings. I also believe ACER racing has free international shipping these days for their bearings. You can give them a look... You can flip the diff rings and use the other side if there is a deep groove in them. But if the balls now have a flat spot in them, they are toast. try rebuilding them like this and turn them by hand. You'll know if they are toast because they will be notchy. Good components (hardened diff balls)+ good diff building(surfacing+ break in)+ proper adjustment = long lasting diffs! Hope this helps a bit! ![]() |

Change the balls and get other diff rings as the stock rings are

just for your information: you can use this type of diffrings also on both sides (on the polished and on the greyish side). so we did it in our old Yokomo K3, K4, K5, SD, CGM und BD...
i use the vampire racing ceramic balls in my diffs right from the beginning, together with the original b-max diff rings. sometimes i clean the diffs but still run the first set of diff rings and balls since a couple of month. normally it helps to clean the thrust bearing and just re-use it. or use hardened thrust balls and rotate the thrust bearing rings from time to time. |

Now, if only you would have added some winks, we might think you were joking. As Phoenix said, he's Flemish, does know how to talk ENglish but hardly learned how to write it. He is a man with a lot of RC-experience (Belgian National Champion 4WD 1/10th offroad 2009) and despite his lack of English-writing skills, still tries to give advice to people who might need it. Why should we bother? ok, and now go ahead and correct all my mistakes as well (I'm also Flemish speaking)
