Performance Delrin Spur for MTX-4

Purpose-built for the Mugen Seiki MTX-4 platform, part number MTX4-0854/V3 from 3Racing, this Delrin spur is specified to reduce mesh losses while maintaining repeatable tooth engagement with 0.8 pitch pinions. The material choice balances low friction and predictable wear for race tuning.

Use the spur for precise drivetrain calibration, particularly when refining acceleration response and gear mesh under competitive conditions. Delrin's sliding properties can lower parasitic drag compared to some harder plastics, aiding consistent lap times when the mesh is set correctly.

Workshop notes: establish correct pinion mesh with minimal preload, verify bearing endplay and washer condition, and conduct controlled break-in runs to stabilise mesh before event use. This part is intended exclusively for RC-scale drivetrains.

What is the expected service life under racing loads?

Service life depends on powertrain torque and setup; with correct mesh and routine inspection, Delrin offers consistent wear patterns suited to regular tuning cycles on club circuits.

Should I pair this with hardened bearings?

Upgrading to high-quality bearings reduces endplay and supports stable mesh under load, improving the performance benefits of the Delrin spur in a competitive setup.

Recommended checks after installation?

Verify mesh under static and light-load running, re-torque mounting hardware after a short run, and inspect tooth profiles for even contact to ensure reliable on-track performance.
