TAMIYA TT02 Aftermarket 42 Pitch 70T Delrin Spur Gear DTT2070T by GPM  [DTT2070T]

70T Delrin spur crafted for TT02 gearboxes

The DTT2070T 70-tooth spur is made to fit the TAMIYA TT02 platform as a swap-in Delrin option. This single 42-pitch spur is suitable for replacing worn plastic spurs or for tuning sessions where drivetrain friction and engagement are under evaluation. It interfaces with standard 42 pitch pinions and the TT02 gearbox assembly.

Choosing Delrin helps achieve stable tooth profiles and lower friction, which can cut down on gear noise and slow surface wear versus some other materials. The spur is well suited for drivers wanting smoother meshing while testing pinion teeth counts, shims, or mesh settings.

Fitting notes: confirm a matching 42 pitch pinion, establish a small clearance in the mesh to prevent binding, check gearbox and axle alignment, and inspect pinion and bearings for wear prior to final torque. Avoid overclamping the gear to stop deformation.
