64-pitch 91T spur gear

This 91-tooth spur gear is a precision option for 64-pitch RC drivetrains. It provides an accurate tooth profile intended to reduce meshing losses and support consistent power delivery in model car geartrains.

Use this spur gear with a matching 64-pitch pinion to maintain correct tooth engagement. When fitting, verify pinion-to-spur mesh, set appropriate backlash, and inspect for even contact across the tooth face to avoid premature wear.

In tuning work the 91T count offers finer gradation of final gear ratios compared with smaller spur gears, allowing small incremental changes to acceleration and top-end behaviour without altering other drivetrain components.

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 pinion pitch must I use with this spur gear?

Use a pinion of the same 64 pitch standard to ensure correct tooth engagement and reliable mesh.

Any installation tips for best gear life?

Set a modest backlash, confirm parallel shaft alignment, and check mesh under load for even contact to extend gear life.
