Fine-Tune Your YZ-834B with the Yokomo ZB-SG3246 Spur Gear

The Yokomo ZB-SG3246 spur gear pairs a 46T outer ring with a 21T inner gear to deliver cleaner power transfer and reduced drivetrain lash on the YZ-834B Dog Fighter. Precision tooth geometry helps maintain consistent mesh and handling under load, while the fit is tailored for the YZ-834B chassis to ensure straightforward installation and dependable service life.
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 difficult is it to fit the ZB-SG3246 to a YZ-834B?

Installation is direct: remove the old spur, align the new 46T/21T unit on the shaft, set gear mesh correctly and secure fasteners. Basic tools and a careful mesh check are all you need.

What maintenance keeps this spur gear reliable?

Regularly inspect the teeth for wear, clear debris after running and confirm mesh and shaft play. Replacing worn spur gears before damage spreads will protect the rest of the drivetrain.

How should I approach pinion selection with a 46T/21T spur?

Match your pinion to the motor and track conditions: smaller pinions give stronger acceleration, larger pinions increase top speed. Trial different sizes and check motor temps to find the right balance.
