Front Belt Specification for YZ-4

This belt is produced as a replacement part for the YZ-4 line and fits the front belt-drive assembly directly. The model Z4-291-6 designates a 97-tooth count with a 6mm width to ensure correct engagement on YZ-4 front pulleys.

Fitting guidance: remove the existing belt, confirm the pulley alignment and sheath routing, then install the Z4-291-6 keeping even tension across the span. After fitting, turn the drivetrain by hand to verify smooth tracking and tooth engagement before any powered testing.

Tuning notes: tooth profile and belt width affect flex, backlash tolerance and tension range on belt-driven 4WD RC cars. Installing the specified 97T/6mm belt keeps the drivetrain behavior consistent with factory intent.

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 do I confirm the belt matches my YZ-4 setup?

Match the part to the required 97-tooth profile and 6mm running width used in your YZ-4 front routing; check your manual or measure the old belt to confirm.

Will reusing worn pulleys cause issues with a new belt?

Worn or damaged pulleys can accelerate belt wear and cause mis-tracking; replace pulleys that show tooth damage or excessive wear for best results.

Is hand-rotating the drivetrain after fitting necessary?

Yes. Rotating the drivetrain by hand confirms smooth engagement and even tooth tracking before subjecting the system to powered loads.
