This MG317T/0.5M motor gear is a compact pinion designed to suit motors that match the listed module and tooth diameter. Forged from 40Cr steel and finished in hardened black, it improves wear resistance compared with common stock pinions and helps keep power delivery consistent during normal model use.
Key mechanical notes: the pinion has 17 teeth at module 0.5mm with a motor tooth diameter of 3.175mm, a round motor bore, and is held with two 3x3 set screws. Verify your motor shaft dimensions and gear mesh before fitting to ensure correct compatibility.
Installation and tuning role: use this pinion to replace a worn gear or to fine tune final drive ratios. Seat the gear concentrically on the motor shaft, check mesh against the spur gear, and tighten the two set screws progressively to preserve alignment. Small changes in ratio will produce predictable changes in drivetrain behavior.
