MTX-5 7075 Pulley Insert Upgrade - MUGEN AM-MTX-T2202J  [AM-MTX-T2202J]

Aftermarket insert for MTX-5 pulleys

The Arrowmax AM-MTX-T2202J pulley set insert is supplied as a replacement component for MUGEN MTX-5 driveline and pulley assemblies. The 7075 reference in the name identifies the alloy used for the insert, and the part is intended to act as an internal replacement piece rather than a standalone pulley.

Use this insert when refreshing a pulley to restore correct seating and contact surfaces. It is designed for hobbyist work on MTX-5 compatible pulley and gearbox subassemblies and must be checked for fit and alignment before completing reassembly.

When carrying out repairs or tuning, handle the part as a service insert: inspect mating surfaces, confirm clearance and radial runout, then secure the insert in line with standard hobby maintenance practice.
