Technical overview: 64-pitch 76-tooth spur gear

Manufactured to 64-pitch specifications, this 76-tooth spur serves as a replacement or spare in RC drivetrains. It enables adjustment of gearing without the need to change motor or ESC configurations.

Installation advice: pair the spur with a compatible 64-pitch pinion, set an appropriate mesh and backlash, and ensure the spur rotates freely on the shaft with no contact against bearings or gearbox parts. Tighten fixings incrementally and re-check the mesh under light load to protect the teeth.

Performance note: fitting a 76-tooth spur lowers the overall gearing, increasing torque at the wheels and softening throttle response, which is beneficial for improved traction in technical driving. Use the motor pinion tooth count to calculate expected ratio shifts.
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.

How can I verify this will fit my gearbox?

Check that your vehicle uses 64-pitch gearing and measure the spur bore and shaft dimensions against the part to confirm fit before attempting installation.

What is the right way to set backlash?

Establish a small clearance between teeth, seat the gears by rotating under light pressure, then tighten hardware gradually and recheck for smooth engagement without tight spots.

When should I replace a worn spur gear?

Replace the spur if teeth show noticeable wear, chipping, or if you experience persistent slippage; regular inspections will reveal when replacement is needed.
