This Arrowmax AM-MTX-T2202C pulley is an aftermarket 25-tooth unit intended for Mugen MTX-5 chassis where that tooth count is required. The 7075 aluminium and hard surface are relevant to how the pulley resists wear and mates with existing drivetrain parts.
Install the pulley following routine RC drivetrain guidelines: ensure correct alignment with spur and pinion, mount concentrically on the drive shaft, and verify static mesh before use. Avoid excessive clamp force on fasteners and confirm the assembly spins freely once the drivetrain is complete.
Designed as a tuning piece, the pulley helps sustain reliable gear engagement and offers repeatable contact when swapping pinions or spurs on the MTX-5. Consider it part of a balanced setup approach rather than a one-step upgrade.
