Mugen Seiki MTX-4 52T Delrin Spur Gear 0.8 Pitch - MTX4-0852/V3 by 3Racing  [MTX4-0852/V3]

52 Tooth Delrin Spur for MTX-4

This aftermarket Delrin spur is intended for the Mugen Seiki MTX-4 platform, offering a 0.8 pitch, 52-tooth option aimed at tuning gear mesh behavior with a lower friction material.

Delrin (acetal) typically engages smoothly with hardened pinions and helps reduce initial mesh noise while maintaining dimensional stability under standard RC running conditions. The item is supplied as a single spur gear for direct replacement where a 0.8 pitch, 52T unit is required.

When installing, follow MTX-4 service guidance for pinion alignment and backlash, ensure the spur is mounted concentric to the gearbox shaft, and verify free rotation with your chosen motor and pinion. Use minimal lubricant only if it complements your setup and inspect the mesh after a brief run for any binding or excessive clearance.
