my problem has stumped me..........
i'll start with the parts that are in the gear box
-prometheus full helical gears
-systema piston head, cylindar, cylindar head, and air nozel
-guarder spring guide
-modify S110+ spring
i had the original TM box in my G3 sas for a while and oblonged the bushing holes. so i picked up a king arms 8mm bearing gearbox and it seems like no matter what i do i cant keep the motor(pinion gear) from grinding on the bevel.
i have tried adjusting the motor in both direction (moves freely in hand grip) with luck.
i have even moved shimming around on the bevel gear hoping that would solve the problem (nope)
