Peterson Fluid Systems lightweight billet oil pump pulley with 37 HTD teeth for accurate belt engagement. CNC-machined from billet aircraft aluminum and finished with hard coat anodizing for wear resistance, it fits a 5/8" shaft, includes a 3/16" keyway and measures 1.020" wide. The reduced mass design lowers rotating inertia while preserving a precise HTD tooth profile.
