Precision 18T Pulley for Yokomo YZ-4

This hard-anodized aluminum 18-tooth pulley is sized for the Yokomo YZ-4 chassis and offers a stronger contact surface than stock plastic parts. It is intended as a replacement for front, rear, or center 18T pulley locations where improved belt engagement is desired.

For rear belt routing pair this pulley with the rear narrow belt Z4-309-6 to secure correct belt seating and tracking. Confirm belt width and routing before final assembly to prevent premature wear or misalignment.

Installation notes: remove the current pulley, inspect the shaft and bearings for wear, install the Z4-630A with the original fasteners, and verify belt tension and tracking after a short run. The hard-anodized finish helps resist wear from belt contact and maintains consistent engagement during normal RC 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.

Can I fit the Z4-630A into the YZ-4 center pulley position?

Yes. The Z4-630A fits front, rear, and center 18T positions on the YZ-4 when an 18-tooth pulley is required.

Which belt should I use for a rear installation?

Use the narrow rear belt Z4-309-6 as specified to keep the belt seated correctly and tracking true.
