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

42 pitch Delrin 70T spur for TT02 setups

This aftermarket 70-tooth spur, part number DTT2070T, is sized for the TAMIYA TT02 chassis and supplied as a single Delrin unit. It serves as a direct swap for worn spurs or as a mod for dialing in gear ratios on the TT02 transmission. The component is made to work with 42 pitch pinions and standard TT02 gearbox geometry.

Delrin is chosen for its low coefficient of friction and stable dimensional properties, which can help lower noise and reduce abrasion in plastic gear trains. Fit this gear when you want smoother engagement or when experimenting with pinion changes, shims, or mesh tweaks.

Installation advice: pair with a 42 pitch pinion, set a minimal but present backlash to avoid binding, align axles and gearbox components, and inspect bearings and pinion teeth before tightening fasteners. Use moderate torque to secure mounting hardware.
