Yokomo YOKPG6427 27T Pinion (64 Pitch)  [YOKPG6427]

Precision 64-Pitch Pinion Details

This 64 pitch pinion features 27 teeth and is suitable as a direct replacement or spare within 64 pitch gear trains. It is aimed at tuners who want to alter final drive steps without swapping spur gear geometry.

Match the pinion to a 64 pitch spur and decide if the 27-tooth count supports your desired tradeoff between acceleration and top speed. More teeth generally favour higher top speed while fewer teeth improve low-end response. Apply these tuning concepts to achieve the handling characteristics you prefer.

During fitment, pay attention to gear mesh and the parallel relationship between motor shaft and spur gear to prevent early wear and noise. Start with a cautious mesh, rotate through steering travel to confirm clearance, then secure the pinion. Perform a short run-in under light load and inspect engagement afterward.

To maintain drivetrain efficiency, inspect tooth faces for nicks, ensure retention screws remain tight, and swap out any worn mating spur gear. Consistent checks and correct mesh keep performance consistent and extend component life.
