48-Pitch 28T Precision Pinion Gear - Yokomo YOKPG4828  [YOKPG4828]

Pinion for 48-pitch drivetrains

This Yokomo YOKPG4828 pinion is a 48 pitch, 28-tooth scale pinion designed for RC model drivetrain use with an ultra-hard surface treatment noted in the product name. It is intended as a direct replacement or spare part where 48 pitch gearing is used, and its tooth count places it in the common range for tuning acceleration and top-speed balance in electric model cars.

Installation notes: confirm correct mesh with the matching spur gear, make sure the motor shaft is seated and bearings spin freely, avoid excessive preload on the motor bearings when setting pinion position, and rotate the drivetrain by hand to ensure smooth engagement before any powered testing. Use small, incremental adjustments to achieve the desired backlash rather than aggressive tightening.

Tuning role: changing to a different tooth count on a 48 pitch pinion adjusts the overall gear ratio and influences throttle response versus top speed, so this pinion suits fine-tuning gearing for circuit conditions or specific motor characteristics while remaining within 48-pitch standards.
