Overview — Oil Suction Connection 2884787
2884787 is the oil suction connection used on CUMMINS engines to join the oil pick-up line to the pump inlet, keeping the suction path sealed so the lubrication circuit draws oil without air entry. We can supply all the original and replacement part numbers listed below, in stock or available on order — welcome to enquire by part number.
Parts Characteristics
The connection is machined to the original thread and bore specification, sized to match the oil pump inlet and the suction line. The material resists oil and vibration, and the sealing faces accept the original O-ring or gasket. The bore keeps the oil flow smooth to avoid cavitation, and the fitting holds the line securely under engine movement. As an OEM-spec connection, it restores the original suction path without changes to the lubrication layout.
Applicable Models & Applications
This oil suction connection is used on CUMMINS engine installations where the oil pick-up line joins the pump inlet, including the sump-to-pump suction routing on the relevant engine series. The family references 3011046, 3011049, 3102327, 3103206 and 3103223 cover the same suction duty on adjacent builds. Typical applications include generator sets, industrial engines and construction equipment. Confirm the thread, bore size and seal type against the connection removed from your engine before ordering.
Maintenance & Replacement
Inspect the connection for cracks, worn threads, leaking seals and signs of air being drawn into the suction line. An air leak on the suction side shows as oil pressure fluctuation and can damage the pump bearings. When replacing, clean the sealing faces, fit a new O-ring or gasket where specified, and tighten the fitting to the specified torque. Verify the oil level is correct and check for leaks around the connection after the engine has run.
