Delrin Spur for MTX-4

This replacement spur is designed for the Mugen Seiki MTX-4 and is identified as MTX4-0854/V3 from 3Racing. Machined in Delrin for low friction, the gear matches a 0.8 pitch pinion to maintain predictable engagement on tuned drivetrains.

Fit this part when the original spur shows wear or when you want to reduce driveline drag for crisper throttle control. Delrin is chosen for its low-friction properties when paired with common metal or plastic pinions used on the track.

Fitment tips: set the pinion mesh precisely, confirm washer and bearing condition inside the gearbox, and perform a short test run to verify gear alignment and load behaviour before extended use.

Can I use this with custom pinion sizes?

Yes, as long as the pinion is 0.8 pitch and you set the mesh correctly. Different tooth counts are fine if the pitch matches and the gearbox clears the pinion.

Will Delrin reduce gear noise?

Delrin tends to run quieter than some harder plastics under normal load, but proper mesh and bearing condition have a larger effect on overall noise.

Should I change gear oil when fitting this spur?

Check existing gear lube and replace if contaminated; clean contact surfaces and use a light film where recommended for your gearbox type to avoid excess drag.
