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

Delrin 69T spur for TT02

The GPM DTT2069T is a Delrin 42 pitch 69T spur gear produced for use with TAMIYA TT02 radio-controlled chassis. Supplied as 1 pcs, it is intended as an aftermarket replacement or hop-up for the vehicle drivetrain.

Compatibility details: designed for TT02 platforms that require a 42 pitch, 69T spur. Verify both pitch and tooth count against your current spur and pinion before fitting to ensure correct mesh.

Installation guidance: install the spur on the gearbox output shaft or mounting plate according to your TT02 configuration, check axial alignment and backlash with the motor pinion in place, and turn the drivetrain by hand to confirm smooth tooth engagement. Ensure correct bearing support and properly torqued fasteners; avoid forcing the gear onto shafts beyond the intended tolerance.

Tuning considerations: Delrin spurs provide lower friction and quieter engagement than some harder plastics, helping drivetrain smoothness and consistent power transfer when experimenting with pinion sizes or motor timing on the TT02.
