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

High Strength Pulley for MTX Drivetrains

The Arrowmax AM-MTX-T2202I pulley is a precision 20-tooth component turned from 7075 aluminium, intended as an aftermarket replacement for MUGEN MTX series drivetrains. The hard alloy construction helps preserve the tooth form and resist wear during repeated sessions on varied surfaces.

Installation is aimed at experienced model mechanics: strip the original pulley, confirm the shaft key and mating faces are undamaged, fit the Arrowmax pulley in the same location and fasten using the original hardware. Recheck spur alignment and the engagement with the pinion, and make small shim adjustments if you detect any binding.

As a tuning item, this pulley gives consistent engagement and dimensional stability which helps with repeatable drivetrain setups. Include it in standard maintenance checks and inspect for wear when altering motor or spur gear combinations.
