Mugen Seiki MTX-4 Low Friction Delrin Spur Gear 0.8 Pitch 53T Ver. 3 by 3Racing MTX4-0853/V3  [MTX4-0853/V3]

Low-Friction Delrin Spur Gear for MTX-4

This is a replacement spur gear designed for RC-scale use on the Mugen Seiki MTX-4 chassis, supplied under the 3Racing MTX4-0853/V3 part designation. The component is fabricated from Delrin to reduce friction at the mesh and is specified at 0.8 pitch with 53 teeth, Version 3.

Fitment and installation are straightforward for MTX-4 owners: confirm the spur gear seating and centre distance match the MTX-4 gearbox layout, set an accurate mesh with the motor pinion, and verify free rotation before final assembly. This part is intended as a direct replacement or a maintenance spare for vehicles using the same pitch and tooth count.

In tuning terms, a low-friction Delrin spur gear helps reduce drivetrain drag and can smooth power delivery under light load conditions, especially useful when refining gear mesh and checking bearing health. Regular inspection for wear and correct mesh clearance remains important for reliable operation.
