Performance and Application Notes

The Yokomo YOKPG4819 is designed for 48-pitch RC drivetrains and features a 19-tooth profile, allowing measured changes to final drive when combined with a 48-pitch spur gear.

By swapping pinion sizes you change acceleration versus top speed without touching motor or ESC programming. Ensure the motor shaft and spur gear are both 48-pitch for correct tooth engagement and controlled backlash.

Installation notes: slide the pinion onto the motor shaft, set the mesh with the spur tooth profile, and confirm smooth rotation across the suspension range. After initial runs, recheck and tighten mounting hardware and inspect teeth for early signs of wear.

Maintenance tips: keep gear teeth clear of grit, check for wear regularly, and replace the pinion when tooth deformation starts to affect mesh. This gear is intended for 1/10 electric RC cars and should be used with compatible 48-pitch components.
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 do I choose the right tooth count for my track conditions?

Smaller tooth counts typically increase acceleration and reduce top speed, which can be advantageous on tight tracks; higher counts suit long straights. Choose based on track layout and motor characteristics.

Can changing to a 19T pinion require ESC or battery adjustments?

Usually no electrical changes are needed; the gear swap alters mechanical ratio. Monitor motor temperatures and battery load after changes and adjust cooling or gearing further if required.

Are there compatibility limits to be aware of with this pinion?

The main limit is pitch: it must be used with a 48-pitch spur and a compatible motor shaft. Confirm shaft diameter and set screw style to ensure secure mounting.
