HARDDRIVE 301497 POL OIL PUMP BIG TWIN 92-99 EVO ONLY
Manufacturer Part Number: 301497
WPS Part Number: 820-50103
Product Type: Engine
Harddrive oil pumps are made from cast aluminum that is CNC machined to close tolerances and then polished to a high gloss finish. Great value for small dollars! Surplus oil is routed back to the main passage rather than the return to avoid unnecessary filtering and offer the opportunity to upgrade earlier engines to the 81-up oiling system. This oiling system splits bottom and top end oil supply which increases oil pressure to the hydraulic lifters and and top end. They come with gaskets, drive shaft with with keys and snap ring, mounting hardware, check ball and pressure relief valve assemblies.
