Yokomo YOKSG4883 Spur Gear 48 Pitch 83 Teeth  [YOKSG4883]

Spur gear for 48‑pitch systems

This is an RC-scale spur gear designed for 48 pitch gear trains, presented as a direct replacement part for standard 48‑pitch drivetrains. Its role is purely within model gearboxes and drivetrain assemblies, used when adjusting gear ratios or replacing worn components in electric or nitro model setups.

When fitting this spur gear, confirm the pinion (motor gear) uses the same 48 pitch standard to avoid incorrect meshing. Proper mesh is critical: start with a nominal backlash, rotate the drivetrain by hand to verify smooth engagement, then lock components in place. Avoid forcing parts into mesh, and re‑check after a few runs as seating can change slightly.

For tuning, changing the spur tooth count alters overall gear ratio and affects acceleration and top speed characteristics at the model level. Use this gear as part of measured ratio adjustments rather than as a sole solution for performance issues; pair changes with motor and ESC settings to evaluate system behaviour.
