48-Pitch Spur Gear 80T Replacement for 48-Pitch Systems - Yokomo YOKSG4880  [YOKSG4880]

48-Pitch Spur Gear Overview

The Yokomo YOKSG4880 is a spur gear specified as 48 pitch with 80 teeth, intended as a direct replacement part for 48-pitch gear trains in electric RC models. As a core drivetrain component, it sets final drive engagement with the motor pinion and influences gear ratio, operating noise, and wear characteristics.

Installation notes: fit the spur gear onto the gearbox output shaft or hub as required by your chassis, ensure the gear is seated squarely and that any set screws or retaining hardware are tightened to the manufacturer's torque specifications. Check spur-to-pinion mesh carefully; aim for minimal, even backlash to avoid excessive wear or binding. Rotate the drivetrain by hand after installation to confirm smooth engagement before powering the model.

Tuning role and maintenance: changing the number of spur teeth alters the overall gear ratio and therefore affects acceleration and top speed characteristics in typical electric RC setups, so select tooth counts with the rest of your gearing in mind. Regularly inspect the gear teeth for burrs or uneven wear, and verify that bearings and gearbox alignment remain serviceable to prevent accelerated gear damage.
