5mm Shaft 24T 48-Pitch Motor Gear MG524T/0.5M Upgrade by GPM  [MG524T/0.5M]

Performance and gearing impact

The GPM MG524T/0.5M is a precision 24-tooth motor pinion made from 45 steel, offered in 48 pitch and module 0.5mm with a motor tooth diameter of 5mm. It is intended as an aftermarket option for electric RC drivetrains to allow replacement or incremental tuning changes, and it is not suitable for full-size vehicle use.

Fitment relies on shaft diameter and tooth pitch; this pinion is for motors accepting a 5mm motor tooth diameter and matching 48 pitch spur gears. Prior to installation verify shaft compatibility, clearances in the gearbox, and that the mesh lines up correctly with the spur gear.

Installation tips: mount the pinion and secure it with the motor's original set screw or retainers. Set gear mesh using a thin paper method, then adjust the motor position or shims to achieve correct backlash. Re-check fastener tightness after initial runs to prevent loosening.

Tuning advice: swapping pinion sizes like this 24T changes final drive ratio; test one change at a time and log the effect on acceleration and top speed relative to your spur gear choice and motor performance. Use consistent testing conditions to evaluate changes properly.
