Compact Precision Pinion for 48 Pitch Gears

The Yokomo PG-4820A is a hard coated aluminium 20-tooth pinion manufactured for 48 pitch gear trains. It combines low mass with a harder tooth surface to promote consistent engagement and steady performance.

Why Fit an Aluminium Pinion?

Aluminium pinions reduce rotational inertia so acceleration and throttle response improve, and a hard coated finish helps resist surface degradation. Those traits make it a sensible change when trimming lap times or refining handling.

Compatibility and Practical Use

Made for 1/10 scale vehicles using 48DP gearing, this 20T pinion will suit most common motor shafts and mounting arrangements. It is straightforward to fit and is a common choice for routine replacements or modest upgrades.
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 check gear mesh after installing the pinion?

Set a small gap between pinion and spur, then rotate the drivetrain to ensure smooth contact without binding. Adjust until there is consistent contact across the tooth face.

Can this pinion handle frequent club racing?

Yes, the hard coat provides better wear resistance than untreated aluminium, making it suitable for regular use, though very aggressive power setups may need tougher materials.

What routine checks should I perform?

Inspect teeth for wear or chipping, confirm secure mounting, and check mesh after crashes. Keeping the spur gear clean and lightly lubricated will extend pinion life.
