Built Tough for RC Drivetrains

The Yokomo PG-4837A Precision Hard Coated Aluminum Pinion Gear fits 48-pitch systems and provides a reliable 37-tooth option for compatible spur gears. It is designed to maintain consistent mesh and minimise vibration in tuned setups.

Benefits of Hard Coated Aluminum

Aluminum pinions cut weight compared to steel while keeping good strength for most hobby uses. The hard coating helps resist surface wear and extends service life under repeated use.

Fitment and Setup Notes

When fitting the Yokomo PG-4837A check that your spur gear is 48-pitch and set a correct gear mesh before final tightening. Inspect the set screw and pinion seating to avoid runout and ensure smooth engagement.
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 work with non 48-pitch spurs?

No. The tooth profile is made for 48-pitch spurs only, and mixing pitches will cause poor mesh and accelerated wear.

Is the hard coating necessary for casual running?

The hard coating improves resistance to abrasion and is beneficial even for regular weekend use, though casual running will tolerate plain aluminum for a time.

How should I maintain this pinion?

Keep the gear clear of debris, check teeth for wear or burrs, verify gear mesh periodically and replace if teeth show rounding or damage.
