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

Precision 48‑Pitch 23T Pinion for Electric RC Motors

This is a dedicated RC-scale pinion intended for 48 pitch drivetrains, offered as a precision 23-tooth unit with an ultra-hard surface treatment noted in the product name. It is designed to be used within 48 pitch systems and to serve as a direct replacement when you need a hard-wearing pinion for routine tuning and durability testing on electric RC motor setups.

Installation is straightforward for experienced hobbyists: fit the pinion on the motor shaft, check axial alignment with the spur gear, set mesh clearance to the recommended small gap for 48 pitch, then secure the pinion using the motor’s set screw or clamp. Always inspect gear mesh under power at low throttle to confirm there is no binding or excessive backlash.

In tuning terms, swapping tooth counts on a 48 pitch pinion alters final drive ratio predictably, so the 23T option provides a specific step for gear-ratio changes without altering the spur gear. Choose this pinion when you want a durable option for iterative ratio testing, track practice, or when running higher duty cycles that stress the gear face.
