88-Tooth 64 Pitch Spur for R/C Gearboxes

This 88-tooth spur is produced to a 64 pitch tooth standard and is listed under the Yokomo part number YOKR12-6488S. It serves as a replacement or spare for R/C gearbox applications where a 64 pitch spur is specified.

The component transfers rotation from the motor pinion through the gearbox and on to the drive train. Ensuring the spur and pinion match in both pitch and tooth count is vital to preserving gear life and preventing excessive loading on bearings.

Fitment tips: check that the pinion contacts the spur across the full tooth width, confirm correct backlash settings, avoid side loading on bearing surfaces, and run a controlled bedding-in session before heavy use.
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.

Why must the pinion match 64 pitch?

Matching the 64 pitch ensures teeth mesh evenly. A different pitch will produce uneven contact, noise, and rapid wear, so always use a pinion with the same pitch rating.

Is machining ever necessary to accept this spur?

Most installs are direct fit when shaft size and mounting layout match. Only if the bore or mounting pattern differs would light machining or an adapter be required.

How to inspect gear mesh visually?

Hand-rotate the motor and observe the engagement across the tooth face, then measure backlash with a feeler or by gentle load testing. Aim for smooth, centered contact without heavy pressure at the tooth edges.
