Technical Overview

The DTT2071T 71-tooth Delrin spur is a precision moulded aftermarket replacement designed for the TAMIYA TT02 42 pitch drivetrain. It is engineered to deliver consistent tooth engagement and low friction characteristics associated with Delrin materials while maintaining dimensional stability under normal RC operating conditions.

Fit this spur when replacing worn stock gears or when adjusting final drive ratios for tuning purposes. Confirm pinion-to-spur pitch compatibility, establish correct mesh and backlash, and verify gearbox alignment to ensure even load distribution across the gear teeth and to minimise premature wear.

Supplied as 1 pcs, the component is intended for scale RC use on TT02 chassis and should only be used on other platforms if explicitly specified by the original chassis documentation.

What inspection steps should I take after fitting?

After installation, rotate the drivetrain by hand to confirm smooth engagement, then run at low speed to verify mesh and check for abnormal noise or binding.

How does Delrin influence gear life?

Delrin provides improved wear resistance and lower friction versus some soft injection-moulded plastics, helping to sustain consistent mesh and reduce heat buildup under normal loads.

Is special bedding-in required?

No special bedding-in is necessary; ensure accurate mesh, run brief break-in sessions under light load, and recheck backlash for optimal contact patterns.
