Weichai 2260244/SZ Turbocharger Oil Inlet Pipe Assembly

The 2260244/SZ turbocharger oil inlet pipe is a welded assembly designed to deliver pressurized engine oil from the lubrication circuit to the turbocharger bearing housing. It is engineered to withstand high thermal cycles and vibration loads inherent in heavy-duty diesel applications. Constructed from high-temperature alloy steel with precision-formed flares and welded junctions, the component integrates banjo fittings or flange connections specific to Weichai engine architectures. The internal bore diameter and wall thickness are calibrated to maintain required oil flow rates and pressure differentials for optimal turbocharger shaft lubrication and cooling. This part serves as a direct replacement for Weichai OEM number 1001554044. It is applicable across Weichai WP10, WP12, WP13, WD615, and WD10 engine platforms deployed in heavy trucks, construction excavators, wheel loaders, and power generation units. Installation requires new copper sealing washers and torque adherence to OEM service manual specifications.
