7075 17T Pinion Tailored for Mugen MTX

This 17-tooth motor pinion is intended for installation on Mugen MTX chassis when a 17T choice is required for gear ratio tuning. Forged from 7075 hard aluminium, it combines lightweight properties with improved resistance to wear for frequent mesh adjustments.

Installation notes: locate the pinion on the motor shaft, set a correct mesh with the spur gear and tighten the set screw(s). After fitting, perform a brief test run and check that the pinion remains secure and spins freely.

Tuning role: the 17T pinion is meant for fine tuning of acceleration against top speed through gear ratio changes, representing a targeted motor gearing upgrade rather than an entire drivetrain conversion.

Do I need a specific spur gear to use this 17T pinion?

No special spur is required but ensure tooth counts and pitch match and confirm the 17T pinion meshes correctly with your existing spur before purchase.

What checks should I make after fitting?

Verify smooth rotation without binding, check set screw tightness after a short run and inspect the gear teeth for even contact across the mesh.

Can frequent mesh changes damage the pinion?

Repeated adjustments can cause wear over time; 7075 improves durability but regular inspection and timely replacement are recommended if wear appears.
