Hardened 16T First Gear for MTX-4

This replacement first gear is a hardened aluminium 16-tooth unit designed for the Mugen MTX-4 chassis. It is intended to restore consistent engagement and extend drivetrain life compared with worn plastic gears, and is supplied for model car use on the MTX-4 platform only.

Fitment is a gearbox service task: open the gearbox, fit the 16T gear, inspect bearings and spur/pinion alignment, set an appropriate gear mesh, then confirm free rotation before sealing the case. Check mesh and wear after the first runs to ensure proper seating and break-in behaviour.

As a tuning component, the metal first gear supports repeatable engagement which helps when adjusting mesh and diagnosing drivetrain noise. It suits racers and builders who maintain MTX-4 kits and seek a resilient metal first gear option.

Is this compatible with all MTX-4 variants?

It is specified for the MTX-4 first gear position; confirm your chassis variant uses the same gearbox layout before purchase.

Should I change other parts at the same time?

During gearbox service inspect and, if necessary, replace worn bearings and ensure spur/pinion alignment to protect the new metal gear.

How can I verify correct mesh after fitting?

With the gearbox assembled, rotate the drivetrain by hand, listen for binding, and run brief tests then recheck mesh to confirm there is no unusual play or noise.
