GPM MG524T/0.5M 45 Steel Motor Gear 24T (48 Pitch, Module 0.5mm, Motor Tooth Diameter 5mm)  [MG524T/0.5M]

Motor pinion gear overview

This GPM MG524T/0.5M is a 24-tooth motor pinion made from 45 steel, specified at 48 pitch with a module of 0.5mm and a motor tooth diameter of 5mm, designed as an RC-scale accessory for electric models. It is intended for use as a direct replacement or for fine tuning gear ratios in small electric RC drivetrains, not for full-size vehicles.

Compatibility is determined by motor shaft and tooth diameter; this pinion matches motors that accept a 5mm motor tooth diameter and use 48 pitch gearing. Before installation confirm shaft fit and clearance inside your gearbox or motor mount to ensure proper mesh with the spur gear.

Installation notes: secure the pinion on the motor shaft with the original set screw or retaining method, check gear mesh by placing a thin strip of paper between pinion and spur and rotating the drive, then adjust backlash by moving the motor plate or gearbox shims as needed. After initial run re-check set screw torque and alignment.

Tuning role: swapping this 24T pinion changes drive ratio and can slightly affect acceleration versus top speed depending on your spur gear tooth count and motor characteristics; use consistent testing and small incremental steps when changing pinion sizes.
