This Arrowmax AM-MTX-T2202C pulley is an RC-scale drivetrain component intended for Mugen MTX-5 chassis applications where a 25-tooth pulley is required. The product name indicates 7075 aluminium and a hard finish, which are relevant to wear resistance and fit, and should be considered when planning drivetrain maintenance or part swaps.
Install the pulley following standard RC drivetrain practices: ensure proper alignment with the spur and pinion, verify concentric mounting on the shaft, and check mesh under static conditions before running. Avoid over-tightening mounting fasteners and confirm free rotation with the rest of the drivetrain assembled.
As a tuning item, this pulley serves to maintain consistent gear engagement and to provide a repeatable contact surface when swapping parts or adjusting gear ratios on the MTX-5. Use it as part of measured changes to pinion or spur gear setups rather than as a single-step performance solution.
