Part number DTT2070T is a single 70-tooth, 42-pitch Delrin spur intended for fitment in TAMIYA TT02 gearbox assemblies. The design focuses on stable tooth geometry and low sliding friction to promote quieter engagement and predictable wear patterns when paired with a 42 pitch pinion.
Delrin's dimensional stability helps preserve mesh settings during repeated runs, making it useful for controlled tuning work such as pinion swaps, shim adjustments, and mesh fine tuning. Inspect mating components and bearings during installation to ensure optimal performance.
Assembly guidance: confirm 42 pitch compatibility, set a measured backlash to prevent binding, align gearbox and drive axles, and use measured torque on fasteners to avoid distorting gear seating. Check pinion teeth and bearings for wear before finishing the build.
