Weichai 13062194 Turbocharger Oil Inlet Pipe Assembly

The 13062194 turbocharger oil inlet pipe assembly is a critical lubrication component designed for Weichai heavy-duty diesel engines. It channels pressurized engine oil from the main oil gallery to the turbocharger center housing rotating assembly (CHRA), providing essential lubrication and cooling for the turbine and compressor shaft bearings. Constructed from high-temperature resistant steel tubing with precision-formed flanges and banjo fittings, this assembly withstands engine oil pressures up to 0.8 MPa and operating temperatures exceeding 150°C. The design incorporates integrated sealing surfaces for copper or composite gaskets to prevent leakage under dynamic vibration conditions typical in commercial vehicle and construction machinery applications. This part serves as a direct replacement for Weichai OEM part number 13062194 (also referenced as WPB13062194). It is engineered to maintain strict dimensional tolerances for fitment on Weichai WP12, WD12, and WD615 engine platforms commonly installed in Sinotruk Howo, Shacman, and FAW J6 heavy-duty trucks, as well as Weichai industrial power generator sets. Regular inspection and replacement during turbocharger service intervals are recommended to prevent oil starvation and catastrophic turbocharger failure.
