I bought this trk from FGD, I don't know whether it's the 3:1 or 4:1 RC4WD reduction unit. Last night it started to make a lil noise & two hill climbs later the reduction seized up! There was plenty of charge yet, so the brushless motor had ample power, but couldn't spin the GR at all, even after disconnecting from the trans.
Anybody else have this happen?
I got the reduction apart, emery clothed the shaft, but I didn't have anything to hone the bushing in the housing. Lube up with lithium grease & put it back together. The trk up on blocks, the bl motor has spinning for last 20 mins & it sounds ok... I even gripped the wheels by hand for a few minutes to make the motor/gr work pretty hard... it still sounds ok.
I haven't used this trk much at all in the couple yrs I've had it, it might be on its 10th charge.
