Technical summary: motor pinion

The MG315T/0.5M pinion is intended as a compact replacement gear for motor shafts matching its bore and tooth diameter, featuring a 15-tooth layout at a 0.5mm module. Produced from heat-treated 40Cr steel with a blackened finish, the gear is built to preserve tooth form and reduce wear in typical RC service conditions.

Notable spec items include 15T, 0.5mm module and a motor tooth diameter of 3.175mm; the round bore accepts compatible motor shafts. Retention uses two 3x3 set screws that clamp the gear to the motor shaft when tightened evenly.

To maintain reliable drivetrain behavior, ensure the spur gear uses the same module and check mesh after installation. A short break-in period with subsequent inspections will reveal any seating or alignment adjustments needed.

Will switching to this 15T pinion affect gearing and top speed?

Yes. Changing tooth count alters the overall gear ratio; a 15T pinion will shift the balance of acceleration and top speed depending on the spur size, so choose your pinion to achieve the desired drivetrain result.

How do I ensure the spur gear is compatible?

Confirm the spur gear uses a 0.5mm module and that tooth counts are selected to reach your target ratio; module mismatch will cause poor mesh and potential tooth damage.

Any recommendations for running-in a new pinion?

Run the model at low to moderate loads for a short period, then inspect mesh and screw tightness; repeat once or twice to settle parts and confirm no abnormal wear before full-power use.
