MUGEN MTX4 0.8 Pitch 54T Delrin Spur Gear by 3Racing MTX4-0854/V2  [MTX4-0854/V2]

MTX4 Delrin Spur Gear

This 3Racing part MTX4-0854/V2 is a low-friction Delrin spur gear intended for use on Mugen Seiki MTX4 chassis. It is a 0.8 pitch 54T spur gear, Version 2, offered as a direct replacement or spare for MTX4 gear trains. The material and tooth pitch match standard MTX4 spur gear requirements, and the item is described here strictly as an RC-scale component.

Fitment and role: the gear is designed to replace the existing spur in the MTX4 gearbox and to serve as a tuning option where lower meshing drag is desired. As with any spur gear swap, verify pinion compatibility and maintain correct gear mesh to avoid premature wear.

Installation notes: remove the gearbox cover, retain any shims or spacers used on the original gear, install the 54T Delrin spur on the same mounting points, and check axial runout and mesh under slow rotation before reassembling. Use the existing pinion gear and confirm backlash and mesh across the full steering and suspension travel.

Tuning considerations: Delrin offers reduced surface friction compared with some plastics, which can slightly change drivetrain feel. When changing spur gears, reassess gear mesh, slipper or clutch settings, and drivetrain lubrication to maintain consistent performance.
