Tuned Pinion Gear from Yokomo PG-6439A for Accurate Mesh

Hobbyists looking to sharpen drivetrain response will value the Yokomo PG-6439A Precision Hard Coated Aluminum Pinion Gear. With a 64 pitch and 39 teeth, the pinion uses lightweight aluminium to reduce inertia while providing a durable contact surface.

Where It Fits

This pinion is intended to pair with spur gears cut to 64 pitch, delivering reliable engagement across a range of touring and track-focused models. Proper pairing helps maintain smooth power transfer and reduces unwanted noise.

Installation and Care

Before installing the Yokomo PG-6439A, clean the motor shaft and confirm there are no burrs on screw holes. Set your mesh with a feeler or shim method and recheck after a short break-in run. Regular inspections of mesh and fasteners will preserve gear life.
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 work with a different pitch spur?

No. This unit is manufactured for 64 pitch systems and must be matched to a 64 pitch spur for correct operation.

Does the hard coat change gear noise?

The hard coating helps reduce wear and can contribute to smoother engagement, which often results in reduced gear whine when mesh is set properly.

What routine checks should I do?

Check gear mesh after initial runs, inspect for chipped teeth, and ensure set screws remain tight. Clean debris from the mesh to avoid accelerated wear.
