Upgrade the YZ-834B Rear Drivetrain with the Yokomo ZB-503I46

The Yokomo ZB-503I46 46T idler gear is a core replacement for the YZ-834B rear drive train, manufactured to tight tolerances for consistent meshing and reduced wear. Its 46-tooth profile helps deliver smooth torque transfer and improved longevity under load, making it a practical choice for racers and hobbyists who service their rigs frequently.
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.

Will this fit other Yokomo models or only the YZ-834B?

This ZB-503I46 is made to match the YZ-834B's geometry and mounting. Other models may require different idlers or adapters, so check chassis specs before swapping.

Any tips for installing the 46T idler on the YZ-834B?

Align the gear with correct mesh to the pinion and centre gears, use a small amount of thread locker where recommended, and verify free rotation before final assembly.

How should I maintain this idler for long service life?

Keep the gear free of grit, check for burrs after heavy runs, and inspect teeth for wear. Light lubrication on bearings helps reduce friction without attracting debris.
