Precision 64-pitch pinion for R/C gearsets

This Yokomo YOKPG6428 pinion is an R/C-scale gear made for general pinion and drivetrain assemblies. The 64 pitch, 28-tooth specification defines tooth spacing and count, which is required to match 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 alters the overall ratio and changes acceleration versus top speed in model setups. It is not intended for use in real vehicles.

Installation notes: confirm the pinion meshes cleanly with the matching spur gear, check axial alignment on the motor shaft, and secure the set screw(s) without over-tightening. Rotate 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 the tooth contact pattern under light load, and retest the system after each change to confirm the expected 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 my model's gears?

64 pitch denotes the tooth spacing standard used to match pinion and spur gears; both gears must share the same pitch to mesh correctly.

How should I verify gear mesh after fitting the pinion?

Adjust the motor position until teeth contact evenly, secure the motor, then rotate the drivetrain by hand to check for smooth engagement and a consistent contact pattern.

Will a 28-tooth pinion change my vehicle's performance?

Yes. Changing tooth count alters the gear ratio; more teeth raise the effective gearing for higher top speed while fewer teeth favor quicker acceleration. Make changes incrementally and test under the same conditions.
