Spur gear impact on performance

This Yokomo 108-tooth, 64 pitch spur is an aftermarket replacement for model drivetrains. As the primary large gear it sets the effective gearing and dictates how the pinion meshes with the motor to deliver torque and speed to the wheels.

Installation notes: position the spur concentrically on your gearbox output hub or designed spur holder, align the motor pinion for consistent tooth contact, and adjust motor mounts or shims to eliminate binding and excessive backlash. Test rotation slowly under throttle to confirm correct engagement before final clamping.

Tuning role: a 108T spur alters acceleration and top speed relative to smaller spurs when combined with different pinion counts. Use it to experiment with gearing for faster lap times or longer runs, while ensuring bearings and motor load are suitable to avoid extra 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.

How does a 108T spur affect acceleration versus top speed?

Increasing spur tooth count generally reduces acceleration but can raise attainable top speed for a given motor and pinion; pair different pinion sizes to dial in the desired performance balance.

Will using a larger spur increase wear on bearings?

Changing to a larger spur can alter load distribution; make sure bearings are rated and in good condition because improper support can accelerate wear under higher torque loads.

What checks improve spur durability after fitting?

Verify correct mesh, keep the drivetrain clean of debris, inspect teeth for damage periodically, and avoid excessive motor gearing that overloads the spur and pinion teeth.
