MG223T/0.5M 23T 40Cr Steel Motor Pinion for RC Motors by GPM  [MG223T/0.5M]

Technical summary

This MG223T/0.5M motor gear is an RC-scale 23-tooth pinion crafted from 40Cr steel to resist wear during regular model use. It matches motors that require a 0.5mm module and a 2.2mm motor tooth diameter and uses a round motor hole secured with two 3x3 set screws.

Installation guidance: confirm the motor shaft diameter and module before fitting, slide the pinion onto the shaft until the teeth mesh cleanly with the spur gear, then tighten the two 3x3 set screws evenly. Run the model at low throttle to check alignment and backlash before normal operation.

Tuning role: as a direct replacement, this pinion restores correct gear mesh and improves longevity compared with worn stock parts, helping preserve predictable transmission response in your setup. Always verify gear parameters against your motor and spur gear for compatibility.
