Compact 38-Tooth Pinion for Precise Ratio Changes

The Yokomo PG-4838A offers a hard coated aluminium 38-tooth pinion designed for hobbyists who need a lightweight, durable option for gearbox adjustments. It is engineered to balance weight savings with reliable tooth strength.

48 Pitch Fit and Applications

Manufactured to the 48 pitch standard, this pinion meshes with corresponding spur gears for straightforward upgrades and ratio swaps. The PG-4838A suits a range of compatible RC drivetrains.

Why Hard-Coated Aluminium Matters

Hard-coated aluminium pinions such as the PG-4838A reduce rotating mass to aid acceleration and responsiveness, while the coating helps protect against wear in regular running conditions.
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.

What checks should I do after fitting the PG-4838A?

After fitting, verify gear mesh, ensure grub screws are secure, and run the drivetrain by hand to confirm there is no binding.

Does the hard coating prevent all wear?

The hard coating improves wear resistance but does not eliminate wear entirely; routine inspection and correct setup remain important.

Can I change tooth count for different ratios?

Yes, swapping to different tooth counts is a common way to adjust gear ratio, provided the replacement maintains the 48 pitch specification.

Are there special care tips for aluminium pinions?

Keep gears free of grit and debris, check mesh regularly, and replace the pinion if you notice significant tooth or coating damage.
