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

52T Delrin Spur for MTX-4 Projects

This aftermarket Delrin spur is sized for the Mugen Seiki MTX-4 platform, featuring a 0.8 pitch and 52 teeth to alter gear mesh characteristics with a low-friction material option.

Delrin (acetal) often offers smoother interaction with hardened pinions versus typical nylon spurs, helping reduce initial mesh noise while keeping dimensional stability over normal running temperatures. It is supplied as a single replacement spur where 0.8 pitch and 52T are specified.

When installing, verify pinion alignment and proper backlash according to MTX-4 service notes, confirm concentric mounting on the gearbox shaft, and check the assembly rotates freely with your chosen motor and pinion. Apply only light gear lubricant if it suits your setup and re-check mesh after a brief run.
