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

Pinion Gear: 64 Pitch, 29 Teeth

The Yokomo YOKPG6429 is a 64 pitch, 29T pinion designed for R/C drivetrains where a precise change in gearing is required. It is intended to work within 64 pitch gear systems as either a replacement or a tuning component for electric R/C models.

Proper installation involves matching the pinion bore to your motor shaft and securing it with the motor's existing fastening method, for example a set screw or a clamp-style pinion mount. Always confirm shaft fit before completing assembly, and adjust motor placement or use shims to obtain correct mesh with the spur gear to avoid binding.

Fitting this 29T alters the gearbox ratio compared with other tooth counts and will change acceleration and top speed behavior. Make incremental changes and conduct test runs to evaluate the effect on your vehicle's performance.

As part of routine checks, verify the pinion remains tight after a few runs, re-examine mesh alignment, and inspect mating teeth for unusual wear. Replacing a worn pinion is a standard maintenance task for R/C models.
