Yokomo YOKPG4823 48-Pitch 23T Precision Pinion Ultra-Hard  [YOKPG4823]

48-Pitch 23T Pinion for Electric Motor Drivetrains

This pinion is a precision 23-tooth unit made specifically for 48 pitch drivetrains, with an ultra-hard surface treatment that improves wear resistance. It serves as a direct replacement when you need a robust pinion for routine tuning and high-use electric RC motor applications.

Fitting is straightforward for hobbyists familiar with motor pinions: slide the gear onto the motor shaft, align axially with the spur gear, set a small mesh clearance suited to 48 pitch, then secure the pinion with the motor set screw or clamp. After installation, check gear engagement at low throttle to ensure smooth operation and no binding.

From a gearing perspective, swapping to a 23T on a 48 pitch pinion gives a predictable change in final drive ratio, making this size useful for stepwise tuning without altering the spur gear. Choose this pinion when you want a wear-resistant option for testing ratios, practice runs, or heavier duty cycles.
