MUGEN MTX-5 7075 Pulley Set Insert by Arrowmax AM-MTX-T2202J  [AM-MTX-T2202J]

Pulley insert for MTX-5

This Arrowmax AM-MTX-T2202J pulley set insert is an RC-scale replacement component produced for maintenance and tuning of MUGEN MTX-5 driveline assemblies. The product name specifies 7075, indicating the alloy used in the insert design, and the part functions as a direct service item within a pulley set rather than a standalone assembly.

Use this insert when refurbishing or swapping parts within an existing pulley unit to restore contact surfaces and alignment. The component is intended for hobby-grade model work on MTX-5 related pulley and gearbox subassemblies and should be checked for fit against the host pulley before final reassembly.

When planning a tuning or repair session, treat this part as a replacement insert: inspect the mating surfaces, confirm clearance and runout on the installed pulley, and use standard hobby maintenance procedures to secure the insert into the pulley body.
