Mugen Seiki MTX4 Delrin 60T Spur Gear 0.8 Pitch MTX4-0860/V2 by 3Racing  [MTX4-0860/V2]

Delrin 60-tooth spur suited to MTX4 gearboxes

This replacement spur gear is made for Mugen Seiki MTX4 chassis and is supplied under part number MTX4-0860/V2 from 3Racing. The component is a 60-tooth unit at 0.8 pitch, molded in Delrin to reduce rotational friction in 1/10 scale on-road drivetrains.

Fit and application: intended as a direct spare or hop-up for MTX4-series gearboxes that require a 0.8 pitch 60T spur. Always check your chassis and gearbox specifications and match the pinion pitch and tooth count before fitting to ensure correct engagement.

Installation tips: install the spur on a clean hub, check spline tightness and axial runout, and set pinion mesh carefully to prevent binding or excessive backlash. Inspect nearby bearings and axle alignment while the gearbox is open and apply threadlocker only where manufacturer guidance specifies it.

Setup and role: the Delrin construction helps keep drivetrain drag low and maintains steady tooth engagement under normal track and club use; use this part as a routine service replacement or when evaluating drivetrain behavior during tuning.
