MG526T/0.5M 45 Steel 26T Motor Pinion (48 Pitch, Module 0.5mm) by GPM  [MG526T/0.5M]

48-pitch pinion description

The MG526T/0.5M is a 26-tooth motor pinion made from 45 steel, designed to the 48 pitch standard with a 0.5mm module. The motor tooth diameter is 5mm, which suits many small hobby motors across both road and off-road models.

This pinion is commonly used to tweak final gearing or to replace a degraded pinion without changing the motor. Because it follows 48 pitch and module 0.5mm conventions, it will mesh properly only with compatible spur gears.

Fitment advice: make sure the pinion is axially aligned and set the mesh to produce a small, even backlash. Confirm that the motor retains the pinion securely at a 5mm diameter and follow recommended torque values for motor fastenings.

Tuning considerations: moving to a 26-tooth pinion shifts gearing toward higher top speed but reduces low-end torque. Adjust tooth count gradually and perform test runs to optimise for your track and power system.
