Drive pulley overview

The Yokomo Z4-630M serves as the main drive pulley and integrated slipper plate tailored for 4WD YZ-4 chassis. The aluminium pulley body with built-in slipper centralizes the drivetrain connection while maintaining standard fitment for the chassis.

Use is intended for RC-scale YZ-4 models and focuses on transmission duties rather than suspension or motor swaps. The hard anodized surface reduces visible wear without affecting compatibility with existing drivetrain components.

Installation notes: confirm the pulley lines up with your spur and pinion, set slipper tension to suit your track conditions, and inspect bearings and retaining hardware fitted to the car before operation.

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 align the Z4-630M with my spur gear?

Align the pulley so the slipper plate sits parallel to the spur face, then rotate the drivetrain slowly to confirm smooth mesh. Make small adjustments to the slipper pad until the gear engagement is free of tight spots.

Does this kit include mounting hardware or bearings?

The listing describes the main drive pulley/plate assembly only. Verify the seller listing for any bundled screws, spacers, or bearings before purchase.

What slipper adjustment works best on loose surfaces?

On loose or low-traction surfaces, reduce slipper preload to allow more slip under load. Increase preload gradually until you regain consistent acceleration without excessive drivetrain heat.
