Spur gear role in RC drivetrains

This Yokomo spur gear is an RC-scale replacement part specifying 108 teeth with a 64 pitch tooth profile intended for use in model drivetrains. It functions as the main large gear in spur/pinion arrangements and serves primarily to set gear ratio and determine mesh with the motor pinion.

Installation notes: fit the spur gear concentrically on the gearbox output hub or spur holder used by your chassis, align the motor pinion for even tooth contact, and set the mesh so teeth engage without binding or excessive play. Small adjustments to motor position or spacers can correct mesh; always verify rotation under slow throttle before finalizing mounting hardware.

Tuning role: a 108T spur changes overall gear ratio compared with smaller counts, affecting acceleration and top speed tradeoffs when combined with your chosen pinion. Use this part to experiment with drivetrain gearing for lap-time, run-length, or traction preferences while keeping attention on bearing support and motor loading to avoid undue wear.
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.

What does 64 pitch mean and why is it important?

64 pitch describes the tooth spacing standard for the spur and pinion interface, matching pinions and spurs of the same pitch is necessary to achieve correct mesh and prevent premature wear.

Will this 108T spur fit my car?

Fit depends on your chassis clearance and hub interface, check that your gearbox or spur holder accepts a 108 tooth 64 pitch spur and that the pinion can be positioned to set proper mesh.

How should I set gear mesh after installing this spur?

Tighten mounting hardware gradually with the gears engaged at neutral, check for a small visible gap between mating teeth when pressed, rotate to confirm smooth movement, then lock motor or hub position and recheck under light throttle.
