GPM Racing #45 Steel Motor Gear 24T (48 Pitch,module: 0.5mm,motor Tooth Diameter: 5mm) (MG524T/0.5M)

Product overview and usage

The GPM MG524T/0.5M is a 24-tooth motor pinion produced from 45 steel, with a 48 pitch specification and a module of 0.5mm, sized for motors with a 5mm motor tooth diameter. It is supplied as an RC-scale aftermarket accessory for electric models and is not for full-size vehicle use.

Match the pinion to motors that take a 5mm motor tooth diameter and 48 pitch spur gears. Confirm shaft geometry, keyway or set screw location, and internal gearbox clearance to ensure proper engagement with the spur gear and smooth operation.

Fitting advice: place the pinion on the motor shaft and secure with the intended retaining method. Use a paper or feeler technique to set the correct mesh, adjust motor plate or shimming for backlash, and re-check fasteners after initial running to prevent slippage.

Tuning considerations: changing to this 24T pinion adjusts the drivetrain ratio and affects acceleration and top speed in relation to your spur gear and motor setup; make one change at a time and assess results under consistent conditions.

What shaft size and pitch does this pinion require?

It is designed for motors that accept a 5mm motor tooth diameter and pair with 48 pitch spur gears; always verify the shaft and mesh before installation.

Is this suitable for performance tuning swaps?

Yes, as an aftermarket pinion it can be used to change final drive ratios; test changes incrementally and monitor motor temperature and drivetrain behavior.

What basic maintenance helps extend pinion life?

Maintain correct mesh, keep gears free of debris, inspect teeth regularly for wear, and re-tighten set screws after break-in runs. Write Product Review Please sign in your account before you can write any review. Sign In Close
