64-Pitch 29T Pinion for R/C Gear Tuning - Yokomo YOKPG6429  [YOKPG6429]

Pinion for Precision Tuning

The Yokomo YOKPG6429 arrives as a 64 pitch, 29T pinion aimed at R/C drivetrains where precise ratio changes are needed. It is compatible with standard 64 pitch gear systems and works as a direct replacement or upgrade when modifying gearing on electric R/C cars.

Fitting the pinion requires matching its bore to your motor shaft and securing it with the motor's existing clamp or set screw system; always verify shaft fit before locking it in. When installing, check the spur-to-pinion mesh and adjust the motor position or add shims so the teeth mesh evenly without binding.

From a tuning viewpoint, switching to this 29-tooth option will change the overall ratio and thus influence throttle response and top speed. Use gradual tooth-count changes and test runs to tune behaviour rather than making large single jumps.

After installation, routinely confirm the pinion remains tight, revalidate mesh after initial runs, and inspect both pinion and spur teeth for abnormal wear as part of standard R/C care.
