One New Aftermarket Replacement Oil Suction Tube Gasket Fits Case/International Harvester Tractors and Combines
This aftermarket replacement oil suction tube gasket (also referenced as an oil pickup/suction elbow gasket) seals the oil suction tube connection in the Fits International Harvester DT466 and Perkins 1300 diesel engine lubrication system. A proper seal at this junction is essential for maintaining oil pressure and preventing air ingestion into the oil pump. This gasket is a direct replacement for IH/Navistar OEM part numbers 671821C1 and 671821C2 and is used in early DT466 series engines (serial numbers 466775 and below, approximately 1977-1993).
