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

Product Summary: 48-Pitch Spur, 80 Teeth

The Yokomo YOKSG4880 is specified as a 48-pitch spur gear with 80 teeth, supplied as a direct replacement for 48-pitch gear trains in electric RC models. As a fundamental drivetrain item, it defines engagement with the motor pinion and affects gear ratio, noise signature and wear characteristics.

Installation notes: place the spur gear onto the gearbox output shaft or hub according to your chassis, ensuring the gear is seated squarely and that any set screws or retaining hardware are tightened to the manufacturer's torque guidance. Carefully check spur-to-pinion mesh; aim for a minimal, even backlash to prevent undue wear or binding. Rotate the drivetrain by hand after installation to confirm smooth engagement before applying power.

Tuning role and maintenance: switching the spur tooth count changes the overall gear ratio and will therefore influence acceleration and top speed in typical electric RC setups, so plan tooth counts alongside your selected pinion. Inspect gear teeth periodically for burrs or irregular wear and verify bearings and gearbox alignment remain serviceable to avoid premature gear damage.
