Mugen Seiki MTX-4 Delrin 0.8 Pitch 52T Spur Gear by 3Racing MTX4-0852/V3  [MTX4-0852/V3]

Delrin 52T MTX-4 Spur Gear

This 3Racing replacement part is presented for use with the Mugen Seiki MTX-4 platform as a Delrin spur gear with a 0.8 pitch and 52 teeth. It is intended as an RC-scale drivetrain component to alter gear mesh characteristics, offering a low-friction material choice compared with standard nylons.

In practice the part is used to adjust gear ratio response and mesh behavior within the MTX-4 gearbox layout. Delrin (acetal) typically runs smoother against hardened pinions and can help reduce initial break-in noise while maintaining dimensional stability under normal RC operating temperatures. The component is supplied as a single spur gear unit suitable for direct replacement where 0.8 pitch and 52T are required.

When fitting, check pinion alignment and backlash consistent with the MTX-4 service guidelines, verify concentric mounting on the gearbox shaft, and confirm free rotation with the chosen motor and pinion gear. Use light gear lube only if recommended for your drivetrain setup, and inspect the mesh after a short run to confirm no binding or excess play.
