48 Pitch 24T Steel Motor Pinion MG524T/0.5M for 5mm Shafts by GPM  [MG524T/0.5M]

Fitment and compatibility guide

The GPM MG524T/0.5M pinion is a 24-tooth component crafted from 45 steel, specified at 48 pitch with module 0.5mm and a motor tooth diameter of 5mm. It is designed for installation in small electric RC drivetrains as an aftermarket replacement or for ratio tuning, not for full-size vehicle applications.

Compatibility is determined by motor shaft geometry and pitch; this pinion suits motors that accept a 5mm motor tooth diameter and pair with 48 pitch spur gears. Always verify keyway or set screw position and available clearance inside your gearbox or mount to ensure proper engagement with the spur gear.

Installation guidance: fit the pinion to the motor shaft and secure with the motor's set screw or retaining method. Use a thin feeler or paper to set mesh, adjust motor plate or shims to correct backlash, and re-check fasteners after a short test run to confirm alignment and security.

Replacement note: this is an aftermarket upgrade component; confirm tooth count, pitch, and shaft fit before substituting it for an OEM or existing pinion. Small step changes in gear sizes help evaluate handling and drivetrain stress safely.
