Mugen MTX-5 2nd Gear 20T by Arrowmax AM-MTX-T2718  [AM-MTX-T2718]

2nd Gear 20T for MTX-5

This Arrowmax part is a hardened 20-tooth second gear, produced for use with Mugen MTX-5 chassis drivetrains, offering a direct replacement option where a durable 7075 aluminum gear is required. The component’s primary role is to serve as the intermediate stage in the gearbox, transmitting torque between the pinion and spur while resisting wear during sustained track use.

When fitting the gear, verify proper gear mesh with the spur and motor pinion, ensure bearings and shafts are free of play, and confirm axial alignment in the gearbox before full-power testing. The 7075 hard material indicates a focus on wear resistance and dimensional stability under load, which supports consistent gear engagement during setup and tuning.

For tuning, consider the gear as part of an overall drivetrain strategy: check backlash, balance load across bearings, and monitor tooth surfaces for uneven wear after initial runs. This part is intended specifically for RC-scale drivetrain use on compatible Mugen MTX-5 models.
