Pinion Gear for Mugen MTX-5

This Arrowmax AM-MTX4-T0724 unit is an RC-scale 16T pinion gear produced for use with Mugen MTX-5 compatible drivetrains, supplied in 7075 hard aluminum. It serves as a direct drivetrain component for adjusting gear ratio and balancing torque versus top speed in model car setups, without implying any road or full-size vehicle application.

In practical setup work the pinion controls final gear ratio and interacts with the spur gear and gearbox components. When replacing a pinion, inspect mating surfaces for burrs, ensure the spur and pinion teeth mesh evenly across their width, and confirm that bearings and motor alignment are free of axial play. Proper mesh and smooth engagement reduce premature wear and maintain predictable throttle response.

For tuning tasks, change the pinion tooth count to alter acceleration and top speed characteristics, then verify consistent engagement under load. This part is an RC-scale accessory intended to be fitted into the existing pinion mounting arrangement of the compatible chassis; do not infer additional adapters or tools are included.
