Yokomo YOKPG4816 - Pinion Gear 48 Pitch 16T, Super Hard Precision  [YOKPG4816]

48 Pitch 16T Pinion Gear

The Yokomo YOKPG4816 is a compact RC-scale pinion gear labeled as a super hard precision pinion gear for 48 pitch systems with a 16-tooth count. It is intended as a direct replacement part for 48 pitch drivetrains where a 16T pinion is required, and its naming denotes a focus on hardened tooth form and manufacturing precision rather than cosmetic finish.

Compatibility and role: this part is designed for 48 pitch gear systems and functions as the motor pinion that defines gear ratio and mesh with the spur gear. Using a precisely cut pinion helps maintain consistent mesh, smooth engagement, and predictable gearing behavior during setup and tuning.

Installation notes: verify the pinion matches your motor shaft diameter and keying before fitting, check gear mesh visually after mounting, and secure the set screw to the manufacturer’s recommended torque to avoid slippage. Small mesh adjustments can be used to reduce noise or tooth wear, and re-check after a short run to confirm there is no loosening.

Tuning role: swapping to this 16T pinion affects overall final drive ratio and can be used to trade acceleration for top speed or vice versa depending on your spur gear choice and motor characteristics. Because the part emphasizes precision, it is suitable where consistent gear engagement and reduced backlash are priorities in setup work.
