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

MTX-5 pulley insert overview

The Arrowmax AM-MTX-T2202J insert is an aftermarket service item for MUGEN MTX-5 driveline assemblies. The part designation references 7075 aluminum alloy, and it is offered as an insert to be installed inside an existing pulley rather than as a full pulley replacement.

Install this insert when refurbishing a pulley to restore bearing and contact surfaces and to correct minor wear. It is designed for hobby-grade work on MTX-5 compatible pulley and gearbox components and should be dry-fitted to confirm compatibility prior to final assembly.

Plan the repair as an insert replacement: clean and inspect mating surfaces, check axial and radial runout, then secure the insert using standard RC workshop techniques for best results.
