MTX-5 Replacement Insert 7075 - MUGEN AM-MTX-T2202J  [AM-MTX-T2202J]

Replacement insert tailored to MTX-5 pulley sets

The Arrowmax AM-MTX-T2202J is supplied as a pulley set insert intended for maintenance and tuning of MUGEN MTX-5 drivetrains. The name indicates 7075 aluminum alloy in the part, and it is intended to serve as an internal service piece inside an existing pulley body.

Use this insert when swapping worn components inside a pulley to regain correct contact geometry and alignment. It is aimed at hobbyists working on MTX-5 compatible pulley and gearbox subassemblies and should be checked for fit against the original pulley before final assembly.

For a smooth installation, treat it as a replacement insert: inspect mating faces, confirm clearance and runout, and use standard workshop practice to seat and secure the insert within the pulley.
