Cummins 3034830 Seal Retainer Assembly

The Cummins 3034830 seal retainer is an OEM component designed to secure the sealing element within the oil transfer tube assembly. It maintains alignment of the oil suction connection to the oil pump, preventing leaks under operating pressure. This retainer is utilized in non-certified 14-liter 855 series engine configurations. Constructed from machined aluminum, the part serves as a clamping plate for the oil transfer tube seal. It is a critical hardware item during engine overhaul or oil pan service procedures. The component interfaces directly with the oil pan mounting surface and pickup tube assembly.
