Precision Delrin spur for TT01 gearboxes

The DTT4261T Delrin 42-pitch 61-tooth spur is machined for consistent tooth geometry and reliable engagement in TAMIYA TT01 transmissions. It is intended as an aftermarket replacement that supports routine maintenance and controlled ratio changes during drivetrain tuning.

Install on 42-pitch pinion systems only; confirm axial clearance and set an even, light contact pattern between pinion and spur. Inspect spur hub fitment and related bearings to maintain alignment and minimise wear across the gear train.

From a tuning perspective, a 61T spur reduces overall gearing to favour acceleration. Delrin's low friction and dimensional stability make it a practical material choice for quieter running and predictable engagement under load.

What inspection steps are recommended after fitting?

Verify mesh pattern, torque the spur hub to spec, rotate the drivetrain under low power to check for binding, and recheck after a short break-in run.

How does material choice affect long-term performance?

Delrin offers reduced friction and stable geometry, which can lower noise and provide consistent engagement; however monitor wear as it will differ from glass-filled or metal gears.

Are there setup tips for tight clearances?

Use thin shims to fine-tune mesh, ensure bearings are fully seated, and confirm pinion axial position to prevent edge loading on spur teeth.
