Tune your drivetrain with the Yokomo PG-4840A pinion

The PG-4840A is a finely machined 40-tooth pinion produced from hard-coated aluminium to deliver accurate tooth profiles and light weight. Its 48-pitch sizing ensures compatibility with standard spurs, offering stable engagement and consistent performance on track or trail.

Why hard coating matters

Hard coating adds a protective layer that reduces surface wear and improves resistance to abrasion. For the PG-4840A this means longer intervals between replacements and more consistent gear mesh under extended running sessions.

Application notes

This pinion suits a broad range of 1/10 scale cars that use 48-pitch gearsets. It is a useful swap when you want to change ratios or replace a worn steel or aluminium pinion without adding unnecessary weight.
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.

Can I change gear ratios with this 40T pinion?

Yes. Replacing the pinion with different tooth counts alters the final drive ratio; ensure the new tooth count still gives correct mesh with your 48-pitch spur.

Should I use grease or oil on the gears?

Light gear grease on the spur and pinion contact area helps reduce wear and noise. Avoid heavy oils that can fling off and attract dirt into the mesh.

Is aluminium pinion noise louder than steel?

Aluminium can transmit slightly different tonal characteristics than steel, but the hard coating and precise machining on the PG-4840A help keep noise and vibration to a minimum when mesh is set correctly.
