Weichai 612600112465 Turbocharger Oil Feed Pipe Assembly

The 612600112465 turbocharger oil feed pipe is a critical lubrication component engineered for Weichai WP10, WP12, and WP13 series heavy-duty diesel engines. It channels pressurized engine oil from the main gallery to the turbocharger center housing rotating assembly (CHRA), ensuring hydrodynamic bearing lubrication and cooling under high thermal loads. Constructed from high-strength carbon steel tubing with a flexible high-temperature rubber hose section and precision-formed banjo or flange end fittings. The assembly includes integrated sealing surfaces compatible with copper crush washers or O-ring seals to prevent leakage at connection points. Designed to withstand engine oil pressures up to 4.0 bar and continuous exposure to temperatures exceeding 150°C. Direct OEM replacement for Weichai Power part number 612600112465. Validated for fitment on Shaanxi Shacman, Sinotruk Howo, Foton Auman heavy-duty trucks, and XCMG, Sany, LiuGong construction machinery platforms equipped with Weichai power units. Installation requires torque tightening to OEM specifications to ensure sealing integrity and prevent oil starvation failure.
