Center/Rear Drive Pulley for YZ-4

This is a standard drive pulley designed for the 4WD YZ-4 off-road chassis. The component serves as the pulley flange used in the center and rear sections of the drivetrain, keeping the belt or gear interface aligned and replacing worn units during routine maintenance.

The pulley uses an 18T tooth profile and the same basic part fits both center and rear positions; the difference between positions is the flange thickness, with a thinner flange intended for the center location and a thicker flange for the rear location. Use the thinner flange where clearance to adjacent parts is tighter, and the thicker flange where extra lateral support is required.

Installation notes: confirm orientation by flange thickness before assembly, verify proper seating on the shaft or hub, and check runout after installation. For tuning, swapping flange thickness can help correct minor lateral belt alignment or mesh issues without changing other drivetrain geometry.

Supported Chassis 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.

Is this pulley compatible with both center and rear on the YZ-4?

Yes, the same 18T pulley fits center and rear positions, note the flange thickness difference for correct placement.

Which flange goes in the center and which in the rear?

The thinner flange is intended for the center position, the thicker flange for the rear position.

Any quick installation tips to avoid alignment issues?

Check flange orientation, ensure proper seating, and inspect runout and belt/gear mesh before finalizing assembly.
