16-Tooth 48 Pitch Pinion Overview

The Yokomo YOKPG4816 is a precision 16T pinion intended for RC 48 pitch gear systems, featuring a super-hard finish to resist wear. It is intended as a replacement motor pinion where a durable, accurately cut 16-tooth gear is required.

Compatibility and role: this pinion is built for 48 pitch spur gears and acts as the motor-side gear defining mesh and ratio. Using a precisely machined pinion helps preserve consistent tooth contact, lowers the chance of irregular engagement, and stabilizes drivetrain response during adjustments.

Installation notes: make sure the pinion matches the motor shaft diameter and any keyway before pressing it on. Set mesh by eye and secure the set screw firmly but not excessively. Perform a short, low-load run to verify there is no slippage or abnormal gear noise.

Tuning role: selecting a 16T pinion modifies the drive ratio and can be part of a tuning strategy to balance acceleration and top speed. The hardened profile makes it appropriate for setups where repeatable mesh and reduced tooth wear are important.
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 competitive club racing setups?

Yes, its hardened teeth and precise cut are suitable for competitive tuning where consistent mesh and low wear matter, provided your class allows 48 pitch components.

How should I check gear mesh after fitting?

Place a strip of paper between pinion and spur, slide to set contact, then tighten the set screw. Remove the paper and ensure contact remains even along the tooth face; run briefly and re-inspect.

Does the hardened treatment change break-in needs?

Because the pinion is hardened, aggressive break-in is not required. Still, a short low-load run and a re-check of mesh and screw tightness is recommended to confirm stable operation.
