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

Replacement Pulley for MUGEN MTX Family

The Arrowmax AM-MTX-T2202I is a 20-tooth pulley turned from 7075 aluminium, supplied as an aftermarket replacement or upgrade for MUGEN MTX drivetrains. The hardened aluminium construction helps retain accurate tooth profiles and resist wear under regular competition and hobby use.

Installers should remove the original pulley, inspect the shaft key and mating faces, fit the Arrowmax pulley in the original location and tighten with the existing hardware. After fitting, check spur alignment and the pinion engagement and inspect surrounding bearings, adding thin shims if any binding appears.

As an aftermarket tuning component, this pulley supports consistent tooth engagement and dimensional stability across repeated runs. Regular inspection is advised, particularly when changing motor or spur gear setups.
