17T 7075 Pinion Upgrade for Mugen MTX

This 17-tooth motor pinion is built to suit Mugen MTX chassis where a 17T option is needed to refine gear ratios. Machined from 7075 hard aluminium, it offers a low-weight profile with improved wear resistance for repeated mesh adjustments.

Installation notes: slide the pinion onto the motor shaft, set the mesh against the spur gear with proper clearance, and fully tighten the set screw(s) before running. After initial installation perform a short test run and re-check fasteners and mesh tightness.

Tuning role: the 17T pinion is intended for incremental changes to acceleration versus top speed through gear ratio tuning and should be viewed as a component-level upgrade to motor gearing rather than a full drivetrain overhaul.

Will this pinion fit my Mugen MTX motor shaft?

The pinion is specified for Mugen MTX compatibility. Verify your motor shaft diameter and keying style and confirm 17T matches your spur gear before ordering.

What is the best way to set gear mesh?

Start with the motor mounted loosely, mesh the pinion to the spur until a finger nail test shows slight contact, tighten mounting screws, then run briefly and re-check for smooth rotation and minimal play.

How does 7075 perform versus softer aluminium?

7075 hard aluminium has greater strength and wear resistance than standard softer alloys, but regular inspection of teeth and mesh alignment is still recommended for longevity.
