2 gearboxes 2 gear diffs both bind?
Whilst in mid motor configuration i have tried 2 new gearboxes and 2 gear diffs and when the gearbox is tightened up it binds?
ball diff in both gearboxes works fine but both gear diffs are not allowing me to fully seal the gearbox. any ideas? ,there is no side to side movement in the gear diff so is it just too big ? |

just unscrew a wee bit the gearbox screws and it will be fine.

Yep i did that, but when you screw it into the chassis it tightens back up again.

I had that issue, I simply loosened the screws until it freed up.

Hi,
I tried that which is fine out if car. As comment above as soon you screw the gearbox to chassis it tightens up again. Thanks.

My guess is that you've warped the plastic as a result of overtightening the screws. These screws only need to be snug, NOT tight (the ones into the alloy motor mount can use a dab of loctite). But once you've warped the plastic you've ruined the parts, and they have to be replaced. Do as others have suggested and buy new gearbox halves, and assemble and re-install WITHOUT overtightening any of the screws. I'll bet your "problem" will be solved. |

The first gearbox i noticed the lid on the gear diff had been over tightened and the plastic had "butterflied" kind of so i bought a new one, this lid was straight and it still bound, as stated above its pinching the bearings not binding on plastic. If i put the ball diff in everything runs free. |

Are you sure you're even using the correct geardiff? |

Trust You lol, You know i have a ball diff as well
Anyway, whilst playing tonight ready for Sunday i measured this: Sorry for the huge crappy iphone pics but im a tad inebriated, Anyways i believe this to be my issue, when screwing the Gearbox up the geardiff goes tight, the ball diff does not. |

Hi,
Yeap I measured the same as you.. Was talking to nice TLR representative Tuesday night and he had no issues with fitting his gear diff. Then he mention he sanded down the "Top hat" side by about 0.5mm to give the diff a smoother action as it was felt the gears were just touching each other. By gently sanding this side down (800 grit) it allows the crown gear to sit closer to the internal gears. So measured his geared diff and would you know it, it measured 17mm!! Not had time to do it yet but feel this is the answer and root cause. Thanks.

Clean your nails Pimlott My din dango had the oversize problem in width even on the second batch of geared diffs. So I got a knife on it and took some material away. What you really need is a hobao
