TAMIYA TT02 Delrin 42 Pitch 69T Spur Gear DTT2069T by GPM  [DTT2069T]

TT02 Delrin replacement spur

The GPM DTT2069T is a Delrin 42 pitch 69T spur gear made to fit TAMIYA TT02 chassis layouts in radio-controlled vehicles. It is supplied as 1 pcs and is intended as a direct RC-scale replacement or hop-up item for the model drivetrain.

Compatibility note: this spur is intended for TT02 variants that use a 42 pitch, 69T spur. Check tooth count and pitch against your existing spur and pinion to confirm correct mesh before fitting.

Installation notes: fit the spur to the gearbox output shaft or mounting plate according to your TT02 arrangement, verify axial alignment and backlash with the motor pinion installed, and rotate by hand to confirm smooth engagement. Use proper bearing support and secure fasteners to chassis specifications; do not force the gear onto shafts beyond the intended interference fit.

Tuning role: as a Delrin spur, the DTT2069T offers lower friction and quieter mesh than some harder plastics, helping drivetrain smoothness and consistent power transfer when testing pinion sizes or adjusting motor timing on the TT02.
