17-Tooth 7075 Pinion Made for Mugen MTX

This 17T pinion is designed to fit Mugen MTX chassis when a 17-tooth option is desired for adjusting gear ratios. Constructed from 7075 hard aluminium, it offers a compromise of low mass and enhanced wear resistance for repeated setup work.

Installation notes: slide the gear onto the motor shaft, adjust and secure correct mesh with the spur gear, then lock the set screw(s). Run a short test and re-check mounting tightness after initial use.

Tuning role: the 17T pinion supports small changes to acceleration versus top speed through gear ratio tuning and is a targeted upgrade for motor gearing rather than a complete drivetrain replacement.

Is this suitable for all Mugen MTX variants?

It is listed as compatible with Mugen MTX chassis; confirm your motor shaft dimensions and that a 17T pinion suits your spur gear before fitting.

Should I use threadlocker on the set screw?

A mild threadlocker can help prevent loosening, but use one suitable for small fasteners and avoid overapplication to allow future removal.

How often should I inspect the pinion?

Check teeth and mesh after a few runs and inspect periodically during heavy use; replace the pinion if you notice rounded or chipped teeth.
