8866 Oil Pump Gaskets, O-rings and Seals for Big Twin & Twin Cam

This James Gaskets kit provides the essential components required for servicing or rebuilding OEM oil pumps on Big Twin and Twin Cam engines. Sold as a set, it includes all necessary gaskets, seals, O-rings, and hardware to ensure a leak-free seal and reliable oil pressure. James Gaskets is renowned for precision engineering, using materials that meet or exceed original specifications to handle the thermal and chemical demands of the Harley-Davidson lubrication system. This kit replaces OEM part 8866 and is designed specifically for factory pump housings rather than aftermarket S&S units. Proper installation requires following factory torque specifications, as gasket thickness varies by application. This comprehensive solution simplifies maintenance by providing all required sealing elements in one package.
