Hardened 40Cr pinion for performance

This MG317T/0.5M motor gear is an RC pinion tailored for compact motors that match the stated module and motor tooth diameter. Made from 40Cr steel with a hardened black finish, it is intended to offer superior wear resistance over common stock gears and to stabilise power transfer during normal operation.

Important dimensions: 17 teeth at module 0.5mm, motor tooth diameter 3.175mm, round motor bore and retention via two 3x3 set screws. Confirm shaft size and mesh clearance prior to fitting to ensure a correct match.

Performance notes: use the pinion when replacing worn gears or when adjusting final drive ratios. Fit concentrically, set proper mesh with the spur gear and tighten both set screws progressively to maintain alignment. Small ratio adjustments will affect acceleration and top speed predictably.

Will changing to this 17T pinion affect acceleration?

Yes. A 17T pinion changes the final drive ratio; smaller or larger pinions will trade top speed for acceleration or vice versa. Test incremental changes to find the balance you want.

How precise must the pinion-to-spur mesh be?

Mesh should be set with a small, even clearance to avoid binding or excessive tooth contact. Check mesh at the motor pinion's installed position and run the drivetrain briefly at low speed to confirm there is no noise or binding.
