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

TT02 Delrin spur upgrade

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

Compatibility guidance: this item is made for TT02 configurations that call for a 42 pitch, 69-tooth spur. Double-check tooth count and pitch relative to your current spur and pinion to ensure correct mesh before installation.

Fitting advice: mount the spur on the gearbox output shaft or appropriate plate in your TT02 layout, set axial alignment and backlash with the motor pinion fitted, and rotate the assembly by hand to confirm smooth engagement. Use correct bearing support and torque fasteners to the chassis specification; do not force the gear onto the shaft beyond its intended fit tolerance.

Tuning impact: as a Delrin component, this spur provides a quieter, lower-friction mesh versus harder plastics, aiding drivetrain smoothness and predictable power delivery when changing pinion sizes or tweaking motor timing on the TT02.
