Yokomo SG-64109 Precision 64 Pitch Spur Gear 109T  [SG-64109]

Precision 64 Pitch Spur Gear

This Precision 64 Pitch Spur Gear from Yokomo is an RC-scale replacement spur designed for general-purpose use in hobby drivetrains. With 109 teeth and a 64 pitch profile, the gear focuses on accurate tooth engagement to keep meshing consistent under typical model loads.

Compatibility is broad by design: the part is intended for general R/C gearboxes and drive trains that accept 64 pitch spur gears. Installation requires pairing with a 64 pitch pinion gear to maintain correct tooth contact, and standard mesh adjustment procedures apply to protect teeth and bearings.

For tuning, this spur plays a straightforward role—its higher machining precision helps maintain steady power transfer and reduces variability in the mesh compared with lower-precision gears, making it useful when refining drivetrain smoothness and gear engagement in everyday RC setups.
