Peterson Fluid Systems lightweight billet oil pump pulley in a 36-tooth HTD layout with a wider 1.250" face. CNC-machined from billet aircraft aluminum and hard coat anodized for durability, it accepts a 5/8" shaft and uses a 3/16" keyway. The increased width provides extra belt contact area while the reduced mass helps lower rotating inertia in accessory drives.
