MUGEN MTX Pulley 20T 7075 Hard by Arrowmax AM-MTX-T2202I  [AM-MTX-T2202I]

Pulley for MUGEN MTX series

This Arrowmax AM-MTX-T2202I pulley is an RC-scale transmission component machined from 7075 aluminium, intended as a direct replacement or upgrade for compatible MUGEN MTX drivetrain assemblies. The 20-tooth profile is used in the pulley train to transfer torque between spur and input stages, and the hardened aluminium construction focuses on wear resistance in model-level service conditions.

Installation is straightforward for experienced hobby technicians: remove the original pulley, verify the mating faces and keyways on the shaft, fit the Arrowmax pulley onto the same location, and secure with the original hardware. Check alignment with the spur gear and inspect surrounding walk-bearing(s) and pinion engagement, making minor shimming adjustments where needed to avoid binding.

For tuning, the pulley serves as a stable aftermarket option when you need consistent tooth engagement and dimensional stability under repeated runs. Because it is an RC accessory, consider routine checks during maintenance cycles and inspect for wear when changing motor or spur gear setups.
