Cummins 4914197 Turbocharger Oil Return Tube

This component is the turbocharger oil return tube, also referenced as 4914197-20, designed to route oil from the turbocharger bearing housing back to the engine crankcase. It is a critical part of the turbocharger lubrication system preventing oil accumulation and seal failure. The tube is manufactured to Cummins OEM specifications for precise fitment on high-horsepower industrial and marine diesel engines. Compatible with Cummins K38, K50, ISLe, and 6BT engine platforms used across construction machinery, power generation, marine propulsion, and heavy-duty truck applications. The assembly includes the tube structure and necessary sealing interfaces. Regular inspection during turbocharger service intervals is recommended to ensure unrestricted oil flow and prevent carbon blockage.
