Yokomo YOKPG6429 - Precision Pinion Gear 64 Pitch 29T  [YOKPG6429]

Precision 64-Pitch Pinion

The Yokomo YOKPG6429 is a precision pinion intended for R/C scale use, presented as a 64 pitch, 29-tooth option for drivetrain adjustments. It is designed to work within 64 pitch gear systems and to serve as a simple replacement or tuning piece when changing gear ratios on electric R/C models.

Installation requires matching the pinion bore to your motor shaft and securing it using your motor's existing fastening method, such as a set screw or clamp type pinion mount; always confirm shaft fit before final assembly. When fitting, check mesh with the spur gear and adjust the motor position or use shims to achieve a correct, even mesh without binding.

From a tuning perspective, swapping to this 29T pinion alters the overall gear ratio compared with higher or lower tooth counts, affecting acceleration response and top speed characteristics in an R/C context. Use incremental changes and test runs to dial in desired behaviour rather than large, single-step changes.

Routine checks after initial installation include verifying secure fastening, confirming mesh after a few runs, and inspecting for unusual wear on mating teeth; replacing a pinion is a common maintenance step in regular R/C upkeep.
