Yokomo YOKSG4880 - Spur Gear 48 Pitch 80 Teeth, spur gear replacement for 48-pitch systems  [YOKSG4880]

Spur gear for 48-pitch systems

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 basic drivetrain component, it defines final drive engagement with the motor pinion and plays a direct role in gear ratio, 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 recommendations. Check spur-to-pinion mesh carefully; aim for minimal but 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.
