High-precision 64-pitch 91-tooth spur gear

This 91-tooth spur gear is a precision option for 64-pitch RC drivetrains. It features an accurate tooth profile meant to cut meshing losses and help maintain even power delivery across model car geartrains.

Fit this spur with a matching 64-pitch pinion to preserve correct tooth engagement. During installation, check pinion-to-spur mesh, set a suitable backlash, and inspect the contact pattern across the tooth face to prevent premature wear.

For tuning, the 91T count gives finer steps for final gear ratios versus smaller spurs, enabling subtle adjustments to acceleration and top-end behavior without changing other drivetrain parts.

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.

Which pinion pitch should I pair with this spur gear?

Use a pinion cut to the same 64 pitch standard so tooth profiles mesh correctly and provide reliable engagement.

How should I set mesh and backlash for longest life?

Leave a small, controlled backlash, confirm shafts run parallel, and test contact under a light load to ensure even tooth contact and extended service life.
