Upgrade the YZ-834B Drive with the ZB-SG3246 Spur Gear

The Yokomo ZB-SG3246 combines a 46T outer gear with a 21T inner gear to promote smoother torque transfer and improved drivetrain consistency on the YZ-834B Dog Fighter. Engineered to match the chassis mounting points, this spur gives tuners a reliable component for sharpening on-track performance and reducing drivetrain noise.
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.

Does this spur need any mod work to fit the YZ-834B?

No modifications are typically required. The ZB-SG3246 is made to align with YZ-834B mounting, though checking gear mesh and screw torque after fitting is recommended.

What signs indicate the spur is worn out?

Look for chipped or rounded teeth, increased drivetrain lash or uneven engagement. If you notice abnormal noise or slipping under load, swap the spur before it affects other gears.

Is the ZB-SG3246 suitable for high-torque motors?

The gear is built for standard racing use on the YZ-834B. For very high-power setups, monitor wear and verify the rest of the driveline can handle increased loads.

Any tips for setting gear mesh on this unit?

Start with a paper-thin shim test to set a snug but free mesh, then run and recheck after a few minutes of operation. Correct mesh reduces noise and prolongs teeth life.
