RC motor pinion specifications and fit

The MG318T/0.5M motor gear is built as an RC pinion for motors that match a 0.5mm module and a 3.175mm motor tooth diameter. Fabricated from hardened 40Cr steel, it improves wear resistance over standard gears and holds an accurate tooth profile under load for consistent power transfer.

The component features 18 teeth and a round motor bore sized for a 3.175mm motor tooth diameter, secured in place with two 3x3 set screws. Before ordering, confirm the motor shaft diameter, module, and required tooth count to ensure compatibility; only motors matching these specs are suitable.

For installation, verify proper mesh with the spur gear, avoid excessive preload, and tighten the set screws so the pinion is stable without deforming the shaft; correct engagement reduces premature wear and preserves drivetrain performance.

Compatibility depends on the motor shaft and module: the pinion fits a 3.175mm motor tooth diameter and 0.5mm module. If your motor matches those dimensions it can be used with either motor type.
The pinion uses two 3x3 set screws to secure the bore to the shaft. They are standard sizes and can be replaced if needed; ensure replacements match the original dimensions.
