V3 gearbox frustration

Recommended Posts

Well, here I am again. A broken gun in one hand, and a shaking fist for the other. I won an ak in a contest not too long ago. I have no clue what brand it is; which may be part of my problem. I have a retro arms gearbox (bought mainly for the quick change function) and an Echo 1 red torque motor. No matter what I do, the motor pinion is pressing down hard onto the bevel gear. I have tried every combination of shims and lack thereof all to result in a horrific grinding noise. There is no play between the two gears either. I'm at a complete loss. I have tried a new motor cage, new and stock motor, 3 different pinions, and 2 gearsets. What am I missing?
