Yokomo PG-6439A Pinion for Consistent Gear Engagement

For racers and weekend builders focused on drivetrain consistency, the Yokomo PG-6439A Precision Hard Coated Aluminum Pinion Gear is a solid upgrade. It features 39 teeth in a 64 pitch profile and lightweight aluminium construction to keep rotational mass down while delivering durable tooth surfaces.

Compatibility Notes

The PG-6439A is compatible only with spur gears cut to 64 pitch, providing dependable mesh and reducing the risk of stripped teeth. It is appropriate for a variety of competitive and hobby setups where gear accuracy matters.

Practical Installation Tips

When fitting the Yokomo PG-6439A pinion, ensure the motor shaft is clean and the set screw holes are clear. Fine tune the mesh and retighten after a short run-in. Periodic checks of mesh and teeth condition help maintain peak performance.
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.

Is this pinion interchangeable with 48 pitch parts?

No. The gear teeth are cut to 64 pitch and must be paired with a 64 pitch spur for correct operation.

Will this reduce drivetrain weight?

Yes. The aluminium construction reduces rotational mass compared with some steel options, which can help response and acceleration.

How often should I inspect the pinion?

Inspect the pinion after heavy runs or collisions, and check mesh alignment routinely. Replace if teeth show deformation or consistent wear.

Do I need special tools to fit it?

Basic tools like hex drivers and feeler gauges or shims are sufficient to set gear mesh and secure the pinion properly.
