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

TT02 Delrin spur gear

The GPM DTT2069T is a Delrin 42 pitch 69T spur gear produced for use with TAMIYA TT02 chassis in radio-controlled models. It is supplied as 1 pcs and intended strictly as an RC-scale replacement or hop-up part for the model drivetrain.

Compatibility: designed for the TT02 platform where a 42 pitch 69T spur is required. Verify tooth count and pitch against your existing spur and pinion to ensure correct mesh before installation.

Installation notes: mount the spur on the gearbox output shaft or survey plate per your TT02 layout, confirm axial alignment and backlash with the motor pinion in place, and rotate the system by hand to check for smooth engagement. Use correct bearing support and secure fasteners to the chassis standard; avoid forcing the gear onto shafts beyond the intended fit.

Tuning role: as a Delrin spur, this gear provides a low-friction, quieter mesh compared with some harder plastics, which can help with drivetrain smoothness and predictable power transfer when adjusting pinion size or motor timing on the TT02.
