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

MTX4 Delrin Replacement Spur

This MTX4-0854/V2 Delrin spur is a low-friction 0.8 pitch 54-tooth replacement intended for use in Mugen Seiki MTX4 gear trains. It is supplied as Version 2 and is suitable as a direct spare or replacement for the original MTX4 spur gear.

Fitment and role: the spur is made to install into the MTX4 gearbox as a drop-in alternative to the stock gear, reducing meshing resistance where compatible. Always confirm pinion tooth count and shaft spacing on your MTX4 variant before fitting to ensure proper engagement.

Installation notes: open the gearbox cover, keep any original shims or spacers, mount the 54T Delrin spur at the same location, and rotate the drivetrain slowly to check mesh and axial runout before final assembly. Reuse the existing pinion and verify backlash through full suspension and steering cycles.

Tuning considerations: Delrin typically lowers surface friction compared with some other plastics and can alter drivetrain feel slightly. After swapping spur gears, re-evaluate gear mesh, slipper or clutch settings, and apply light lubrication only where appropriate to preserve consistent performance and minimise wear.
