Sinotruk HG1500111127 Turbocharger Oil Return Pipe Assembly

The HG1500111127 turbocharger oil return pipe assembly is engineered to OEM specifications for Sinotruk Howo series heavy duty trucks. Constructed from high-grade stainless steel alloy, the component withstands extreme exhaust gas temperatures and corrosive oil environments inherent in turbocharger lubrication circuits. The assembly includes precision-formed flanges and integrated sealing surfaces to ensure leak-free connection between the turbocharger center housing and the engine crankcase. Designed as a direct replacement for the factory oil drain line, this unit restores proper gravity-fed oil return flow, preventing oil accumulation in the turbocharger bearing housing which can lead to seal failure and rotor shaft damage. Installation requires adherence to the specified mounting bolt torque of 25 Nm with a new gasket to guarantee sealing integrity. Compatible with Weichai WP10, WP12, WP13 and Sinotruk MC11, MC13 diesel engines equipped on Howo Max, A7, and T7H vehicle platforms.
