Reliable Pinion for Hobby Setups

The Yokomo PG-4837A Precision Hard Coated Aluminium Pinion Gear is a 37-tooth option for 48-pitch systems, designed to keep gear engagement stable across different track conditions. It helps preserve smooth power delivery in tuned drivetrains.

Lightweight with Extra Surface Toughness

Using aluminium keeps rotating mass low for nimble response, while the hard coating adds surface protection to reduce tooth wear during heavy runs. It is a practical compromise between weight and durability.

Practical Setup Tips

Confirm spur pitch is 48 and check the pinion seating on the motor shaft when installing the Yokomo PG-4837A. Fine tune the mesh with shims and recheck after a short test run to avoid binding or excess play.
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.

Will this pinion handle high torque motors?

It will perform well in many setups, but very high torque systems can accelerate wear; check teeth frequently and consider steel pinions for extreme torque applications.

Is special lubrication needed?

Pinions do not need heavy grease on teeth; keeping the area clean and using light bearing lubrication as recommended for your drivetrain is usually sufficient.

How do I check for wear?

Inspect the tooth tips for rounding, check for metal shaving in the gearbox and listen for increased noise during runs; these are signs to consider replacement.
