Weichai 13022003 Turbocharger Oil Return Line Assembly

The Weichai 13022003 turbocharger oil return line is a critical component within the engine lubrication system, designed to channel high-temperature oil from the turbocharger bearing housing back to the engine crankcase. Manufactured to OEM specifications, this assembly ensures precise fitment for Weichai WP series engines including WP10, WP12, and WP13 platforms commonly deployed in heavy-duty trucks and construction machinery. Constructed from high-grade heat-resistant steel tubing with formed flanges, the line withstands thermal cycling and vibration inherent in turbocharged diesel applications. The component features OE-exact routing geometry to facilitate installation in confined engine compartments without modification. Integrated sealing surfaces ensure compatibility with standard copper or composite gaskets to prevent oil leakage under pressure. This part serves as a direct replacement for Weichai OEM part number 13022003. It is applicable to vehicles such as Shaanxi Delong X3000, Sinotruk Howo T7H, Foton Auman, and equipment including Shantui bulldozers and XCMG excavators powered by Weichai engines. Regular inspection and replacement during turbocharger service intervals is recommended to maintain lubrication integrity and prevent bearing starvation.
