Note: This may fit other applications other than the 1FZ but its intended application is the 1FZ. Any usage outside of the 1FZ for the York OBA is outside of the scope of the design and there is no warranty.
On the 1FZ powered 80 Series Land Cruisers there are mounting options for various accessories. One of those accessories is the York On-Board-Air system. In order to drive the York compressor you need to be able to supply a pulley with 3-grooves driven off the water pump. This IS that pulley. CNC machined from billet 60 Series aluminum stock and then Type 2 black anodized for protection. The grooves are carefully machined to match the same Toyota pulley spec used on all Land Cruisers around the world.
