Spur Gear 80T 48-Pitch for Ratio Tuning - Yokomo YOKSG4880  [YOKSG4880]

Role in Gearing and Performance

The Yokomo YOKSG4880 is a 48-pitch spur gear featuring 80 teeth and is intended as a direct spare for 48-pitch gear trains on electric RC models. It forms the mating surface with the motor pinion and has a clear effect on final drive ratio, noise output and wear trends.

Installation notes: install the spur gear onto the gearbox output shaft or hub according to your chassis layout, making sure the gear is seated square and any set screws or retaining hardware are tightened to the manufacturer's torque recommendations. Verify spur-to-pinion mesh and set minimal, even backlash to prevent binding and excess wear. Rotate the drivetrain by hand after fitting to ensure smooth engagement prior to powering up.

Tuning role and maintenance: increasing the spur tooth count shifts the overall gear ratio, typically improving low speed torque while lowering top speed. Check the gear teeth for damage or uneven wear during regular maintenance and keep bearings and gearbox alignment in good order to avoid accelerated failure.
