Overview and fit

The MG223T/0.5M pinion is an RC-sized motor gear with 23 teeth, a 0.5mm module and a 2.2mm motor tooth diameter, finished in durable 40Cr steel. It fits motors with a round motor hole and is tightened in place using two 3x3 set screws.

Fitting advice: check the motor shaft size and module first, then slide the pinion on until the teeth mesh smoothly with the spur gear. Secure with the two 3x3 set screws, ensuring they are tightened evenly to avoid shaft misalignment.

Use case: this pinion is intended as a direct replacement to restore correct mesh and wear characteristics, maintaining consistent drivetrain response when matched with the correct spur gear and motor combination.

Do I need any special tools to install this pinion?

Basic hex drivers to match the 3x3 set screws and a small flat surface to support the motor are sufficient. Use a low-speed check to confirm mesh after tightening.

How tight should the set screws be?

Tighten the two 3x3 set screws evenly until the pinion is secure on the shaft but avoid excessive torque that could damage the shaft. Verify at low throttle for any slipping.

Can I reuse a worn spur gear with this pinion?

For best performance, pair this new pinion with a spur gear in good condition. Reusing a badly worn spur can cause poor mesh and accelerated wear on the pinion.
