Precision 18-Tooth 48P Pinion

This hardened pinion is crafted for 48-pitch RC drivetrains. Its 18-tooth count provides a practical mid-range option for changing final gearing without replacing the spur, helping tuners balance low-end punch against top speed within 48-pitch arrangements.

Ensure fitment by confirming your motor uses a 48-pitch shaft and that the spur gear matches; measure shaft diameter and note set screw placement before installation. Correct mesh and minimal backlash are essential to avoid accelerated wear on both pinion and spur.

For tuning, move the pinion in single-tooth steps and conduct test laps between changes. Apply appropriate locking compound or tighten the set screw to spec, and re-check gear mesh after any break-in or drivetrain adjustment.
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.

Is this pinion suitable for all 48-pitch motors?

It is designed for 48-pitch systems, but you must match shaft diameter and check set screw alignment for your specific motor before use.

How does changing tooth count affect handling?

Increasing teeth raises top speed but reduces acceleration; decreasing teeth gives quicker acceleration at the expense of top speed. Make single-tooth changes and test to find the best compromise.

Any maintenance tips for longevity?

Keep mesh adjusted, inspect for wear after runs, and secure the pinion with the correct torque or thread locker to prevent slippage.
