MUGEN MTX 7075 aluminium pulley upgrade - Arrowmax AM-MTX-T2202  [AM-MTX-T2202]

MTX pulley replacement guide

This pulley set is an RC-scale replacement intended for use with MUGEN MTX chassis where a hardened 7075 aluminium pulley is required. It is presented as a direct-fit option for MTX drivetrains, letting hobbyists address worn contact points and fine-tune gear engagement without changing the core chassis layout.

The focus of the design is transmission tuning: swap the stock pulley to test differences in engagement feel and to assess longer term durability under normal RC running conditions. As with any scale component, check neighbouring shafts, bearings and mating surfaces on your MTX before installing to ensure correct seating and alignment.

Installation is straightforward for those used to MTX service routines: remove the existing pulley, inspect shaft and bearings, install the replacement pulley and verify free rotation and correct mesh. After fitting, run a short low-throttle check to confirm engagement and lateral play, then re-check fasteners before full use.

This part is intended for practical setup work: fit it when you need a hardened 7075 aluminium contact surface in the pulley location to judge longevity or small changes in drivetrain response while tuning.
