YZ-4 18T Hard-Anodized Drive Pulley

Constructed from hard-anodized aluminum, this 18-tooth pulley for the Yokomo YZ-4 gives firmer belt contact versus plastic originals and can be used in front, rear or center 18T locations.

When fitted to the rear belt route this pulley should be used with the rear narrow belt Z4-309-6 to ensure proper belt seating and tracking. Check belt width and path before final assembly to avoid misalignment that can shorten belt life.

Installation guidance: remove the existing pulley, inspect shaft and bearing condition, fasten the Z4-630A with the original hardware, and then verify belt tension and alignment after a brief run. The anodized finish aims to reduce wear from belt contact and keep engagement consistent during normal use.

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 pulley extend belt life compared with plastic?

The hard-anodized surface provides greater resistance to abrasion than plastic, which can contribute to longer belt life when the pulley is correctly aligned and tensioned.

Any setup tips after fitting the Z4-630A?

After installing the Z4-630A, confirm belt tension, check tracking, and perform a short break-in run. Use the Z4-309-6 narrow rear belt if the pulley is on the rear path to maintain correct seating.
