TAMIYA TT02/TT02B 42 Pitch Delrin Spur Gear 71T by GPM DTT2B071T  [DTT2B071T]

Delrin Spur Gear for TT02/TT02B

This 71-tooth, 42-pitch Delrin spur gear is an aftermarket replacement produced by GPM for TAMIYA TT02 series chassis. Designed as an RC-scale drivetrain component, the part is intended to replace the original spur in TT02 and TT02B gearboxes where a Delrin option is preferred for lower friction and quieter operation.

Material and role: Delrin is a common plastic choice on RC parts when a balance of wear resistance and low sliding friction is needed. In a TT02 drivetrain this spur gear is used to transfer rotation from the pinion gear to the gearbox, and its 71T tooth count directly affects final drive ratio and mesh setup.

Installation notes: confirm correct 42 pitch mesh with the motor pinion, set backlash using standard shims or axle spacing procedures, and check axial alignment in the gearbox to avoid binding. When fitting a Delrin spur, recheck mesh after a short run-in since plastic gears can seat slightly under load. This product is supplied as 1pc for single-gear replacement.

Tuning considerations: choosing Delrin can reduce drivetrain noise and provide a slightly smoother engagement compared with some harder plastics, which is useful for routine setup and minor gearing adjustments. Keep lubrication minimal and use compatible pinion gears and bearings to preserve smooth operation.
