Product Brief: 42T 64-Pitch Pinion

The Yokomo YOKPG6442 serves as a straightforward replacement pinion for R/C gear trains running 64-pitch gearing. It transmits motor torque to the spur and, together with the spur tooth count, defines the drivetrain ratio.

Installation notes: verify the pinion matches the 64-pitch spur and that the motor shaft and bore alignment are correct before tightening. Begin with a looser mesh, observe tooth contact across the face, then tweak laterally to equalise engagement. Tighten the set-screw(s) while holding the motor secure, and perform a short test run to ensure the mesh remains stable.

Tuning guidance: selecting a different tooth count on the pinion changes the acceleration versus top speed balance; treat the 42-tooth option as part of stepwise ratio testing. After adjustments, monitor for elevated temperatures, abnormal noise, or visible wear and correct mesh or pinion height as required. Routine care includes removing grit from teeth and checking for nicks that could speed wear on both gears.
Remark :
Due to limited stock availability, please notice that some Yokomo items may have to order from the factory and the ready time is around 4-6 weeks. Customer purchases the item is assumed to accept the waiting time which allows us to order directly from the manufacturer if the item is out of our warehouse.

How should I set the initial gear mesh with this pinion?

Start with a conservative gap and rotate the gears by hand to check contact. Adjust until the tooth contact is even across the face, then secure the set-screw while preventing motor rotation to keep alignment.

What hand tools make the install easier?

A correct-size hex driver for the set-screw, a motor holder or simple clamp to steady the motor, and basic hand tools for access work are typically all that is needed.
