Detroit DD15 Oil Pickup Tube Function

The oil suction manifold is positioned in the lower portion of the engine and provides the oil pump with a controlled path for drawing engine oil from the oil pan. Proper oil pickup is essential for maintaining oil flow through the engine lubrication system.

A damaged, cracked, restricted, improperly sealed, or incorrectly fitted oil suction manifold can interfere with proper oil pickup and may contribute to lubrication problems or low oil pressure.

The Detroit Diesel A4721806851 oil suction manifold is identified for DD13 and DD15 applications using a front-sump plastic oil pan. Detroit service documentation lists different suction manifold part numbers for different oil-pan configurations, including separate manifolds for aluminum oil pans.

Important: Verify the oil pan configuration, OEM part number, VIN, and/or engine serial number (ESN) before ordering. Do not assume every DD15 uses A4721806851.
