Front Belt Details for YZ-4 Chassis

Engineered as a direct replacement for YZ-4 front belt-drive assemblies, the Z4-291-6 specifies a 97-tooth profile and a 6mm running width to restore accurate pulley engagement and routing.

Fitting checklist: remove the old belt, inspect pulleys for wear and ensure correct sheath routing, then fit the Z4-291-6 with uniform tension. Manually cycle the drivetrain to check for consistent tooth engagement and smooth tracking before any powered operation.

Performance considerations: belt tooth count and running width influence stiffness, allowable backlash, and tension settings on belt-driven 4WD RC platforms. Using the specified 97T/6mm belt supports consistent steering feel and predictable drivetrain behaviour during tuning.

Compatibility

  • YZ-4
  • B-YZ4
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 accurate are the listed tooth count and width for replacement use?

The part is specified as a 97-tooth belt with a 6mm width for YZ-4 front routing; fit it when those dimensions are required to match factory geometry.

What prep should I do before installing the new belt?

Clean the pulley surfaces, check bearings and pulley alignment, and confirm the belt path is clear; addressing these items reduces the chance of mis-tracking.

Will the Z4-291-6 alter my vehicle setup?

If you replace like-for-like with the same tooth count and width, the original setup should be retained; always re-check belt tension and alignment after replacement.
