Pinion gear for R/C drivetrains

This Yokomo YOKPG6428 pinion is an R/C-scale gear intended for use in general pinion gear systems and drivetrain assemblies. The 64 pitch, 28-tooth specification identifies tooth spacing and count which matters when matching to spur gears of the same pitch.

Use this part as a direct replacement or as a tuning option when adjusting gear ratios; increasing or decreasing pinion tooth count changes the overall ratio and affects acceleration versus top speed in model setups. It is not intended for real vehicle use.

Installation notes: confirm the pinion meshes cleanly with the matching spur gear, check axial alignment on the motor shaft, and verify that the set screw(s) are secure without over-tightening. Spin the drivetrain by hand after installation to detect binding or excessive play before applying power.

Tuning tips: when swapping pinions keep the same pitch across spur and pinion, inspect tooth contact pattern under light load, and retest the system after each change to confirm intended behavior in your model's setup.
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.

What does 64 pitch mean for a pinion gear?

64 pitch refers to the tooth spacing standard used to match pinion and spur gears, ensure both gears share the same pitch for correct mesh.

How do I check gear mesh after fitting the pinion?

With the drivetrain assembled, adjust motor position until teeth contact evenly, then secure and rotate by hand to confirm no binding and stable contact pattern.

Will changing to a 28-tooth pinion affect performance?

Yes, changing tooth count alters the gear ratio; more teeth generally raise gearing while fewer teeth lower it, so test changes incrementally to reach desired drivetrain behavior.
