64-Pitch 28-Tooth Pinion Gear Yokomo YOKPG6428  [YOKPG6428]

Built for reliable gear engagement

This Yokomo YOKPG6428 pinion is intended for R/C pinion systems and standard drivetrain assemblies. The 64 pitch and 28-tooth size indicate the required tooth spacing and count for compatibility with like-pitch spur gears.

It serves as a direct replacement or a tuning option when changing gear ratios; modifying pinion tooth count changes the overall ratio and shifts the balance between acceleration and top speed. Not for road vehicle use.

Fitment pointers: verify pinion and spur mesh, check that the pinion is square to the motor shaft, and fasten set screw(s) securely but without over-torquing. Hand-rotate the drive train after installation to identify any unusual play or binding before powering up.

Maintenance and longevity tips: inspect teeth regularly for wear, maintain correct mesh to prevent premature damage, and validate changes with short test runs after swapping pinions to ensure consistent results.
