Yokomo YOKR12-6476S - 64 Pitch 76R Spur Gear  [YOKR12-6476S]

64-pitch 76-tooth spur gear for RC models

This is a 64-pitch 76-tooth spur gear designed for RC-scale drivetrain use, intended as a replacement or spare for 64-pitch gear sets. The component focuses on the mechanical role of the spur gear within the drivetrain, allowing hobbyists to adjust gear ratios without altering motor or ESC settings.

Installation notes: match the spur to a 64-pitch pinion gear, ensure proper gear mesh and backlash, and check that the spur rotates freely on the shaft with no binding on bearings or gearbox components. Use gradual tightening and re-check mesh under load to avoid tooth wear.

Tuning role: changing to a 76-tooth spur alters the overall gear ratio to favour lower speeds with more torque at the wheels, useful for setups that need smoother throttle response or improved traction in technical track sections. Use ratio calculations based on motor pinion tooth count to estimate on-track behavior.
