Weichai 610800111388 Turbocharger Oil Inlet Pipe Assembly

The Weichai 610800111388 turbocharger oil inlet pipe assembly is engineered to deliver pressurized engine oil from the main gallery to the turbocharger center housing rotating assembly (CHRA). It is constructed from high-temperature resistant steel tubing with reinforced flexible hose sections and crimped end fittings to withstand thermal cycling and vibration in heavy-duty diesel applications. This assembly is a direct replacement component for Weichai WP4, WP6, and WP10 series engines, including the Deutz 226B platform derivatives. It features precise bend geometry and thread specifications (typically M14x1.5 or M16x1.5 metric flare fittings) to ensure leak-free sealing at the engine block and turbocharger housing ports. Regular inspection and replacement during turbocharger overhaul intervals prevents oil starvation failures.
