Weichai 612600113779 Turbocharger Oil Inlet Pipe Assembly

The 612600113779 turbocharger oil inlet pipe assembly is a critical lubrication system component designed for Weichai WP10 and WP12 series engines, including the WP10CNG natural gas variant. It channels pressurized engine oil from the main gallery to the turbocharger center housing rotating assembly (CHRA) to lubricate and cool the turbine shaft bearings. Constructed from high-temperature resistant steel tubing with precision-formed flared or threaded end fittings, the assembly ensures leak-free sealing under engine operating oil pressures. It is a direct replacement for the factory-installed supply line on Shacman heavy-duty trucks (F3000, X3000, X6000) equipped with Weichai power units. The assembly typically includes necessary sealing washers or O-rings for installation.
