High-Precision 64P Spur, 90T

This replacement spur is manufactured for standard RC drivetrains, offering 90 teeth cut to the 64 pitch dimension. The precise cutting reduces slack between gears and refines interaction with a correctly sized pinion, promoting steadier power delivery under typical electric model conditions.

Fit this spur with a 64 pitch pinion to secure correct engagement. Focus on mesh accuracy and bearing alignment during setup, since the gear's job is to maintain repeatable tooth geometry for reliable tuning and power transfer in the vehicle's gearbox or layout.
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.

Can this spur be used in other 64 pitch drivetrains?

Yes, it matches the 64 pitch profile; just verify the spur's mounting and shaft compatibility with your gearbox before fitting.

Will the 90T size change performance?

The tooth count influences the final ratio relative to your pinion choice, so select a pinion to tune acceleration or top speed while retaining the 64 pitch.

Any recommended mesh checks?

Use a feeler or paper method to set a small, even gap, then rotate the drivetrain to confirm smooth engagement and no binding.
