64T Pinion Gear for 64 Pitch Applications Yokomo YOKPG6440  [YOKPG6440]

64P 40 Tooth Pinion Details

The component sold as Yokomo YOKPG6440 is a standard R/C pinion designed for 64 pitch gear sets and described by its 40-tooth count. It functions as a straightforward mechanical replacement part in electric hobby models that employ 64 pitch gearing.

Compatibility is determined by the motor shaft diameter and matching spur gear pitch, so verify these dimensions before fitting. This item is supplied as the pinion gear only, without extra mounting parts.

Installation normally involves removing or exposing the motor shaft, positioning the pinion, adjusting the gear mesh for correct engagement without too much slack, then fastening the pinion with the motor's original securing method. Do not force the gear onto an incompatible shaft and always test mesh at low throttle first.

Note on gearing: changing tooth count shifts the gear ratio; a 40-tooth pinion at 64 pitch is useful when making small incremental changes to acceleration and top speed. Regular checks for wear and correct mesh will extend drivetrain reliability.
