Yokomo SG-64101 Precision 64 Pitch Spur Gear 101T  [SG-64101]

Precision 64-pitch spur gear

This spur gear is a precision 64-pitch general purpose part with 101 teeth, intended for RC drivetrain use. Its tighter tooth profile reduces meshing error compared with lower-precision gears, helping the drivetrain run more smoothly and with improved mechanical efficiency.

Key considerations when using this part are pitch matching and gear mesh: the gear is made to the 64 pitch standard so it must be paired with a 64 pitch pinion, and careful mesh adjustment is required to avoid excessive wear or noise. Check backlash and mesh under load before finalising setup.

Typical roles for this spur gear include standard replacements, gear-ratio changes for tuning, and use where smoother gear engagement can reduce drivetrain losses. It is a general-purpose component and does not carry brand-specific vehicle assumptions.

Installation and tuning tips

• Confirm pinion pitch: only use with 64 pitch pinion gears.
• Set gear mesh: adjust pinion position to achieve correct tooth contact without binding.
• Test run: verify noise and heat after a short run, then re-check mesh and fasteners.
