Electric RC 38T 64-Pitch Pinion Gear Yokomo YOKPG6438  [YOKPG6438]

Overview: 64-Pitch 38T Pinion

The Yokomo YOKPG6438 is supplied as a 38-tooth pinion cut to 64-pitch standards for electric RC models. It enables straightforward changes to final drive ratios and helps refine drivetrain response under load.

Use this pinion where the system calls for 64-pitch gear geometry; it is compatible with a wide range of gearboxes and motor styles. Always confirm the pinion's tooth count and pitch match the spur gear, and check motor shaft diameter and set screw format before attempting installation.

Installation notes: slide the pinion onto the motor shaft to the correct axial position, set an appropriate mesh clearance to prevent early wear, and torque fasteners to recommended values. After assembly, manually rotate the drivetrain to verify smooth engagement and to spot any abnormal play or binding.

Tuning note: fitting a 38T increases the final drive compared with smaller pinions, shifting the balance between acceleration and top speed; progress in small increments when testing to avoid big handling surprises.
