Cummins 3804535 Lubricating Oil Pump Assembly

The Cummins 3804535 is a gear-type lubricating oil pump assembly designed to circulate engine oil throughout the lubrication system of Cummins 14-liter N14 and 855 series diesel engines. It features an aluminum housing construction for optimal strength-to-weight ratio and corrosion resistance. The pump is driven directly by the engine gear train, delivering consistent oil pressure across operating speeds. This assembly supersedes previous part numbers 3085379 and 3803698. It is engineered for non-certified 14-liter N14 engines including G855, NH855, NT855, and NTA855 configurations. The unit is classified as non-hazardous material for shipping and handling. Applications span heavy-duty trucking, construction machinery such as wheel loaders, and industrial power generation equipment utilizing the compatible engine platforms.
