Cummins 3073695 Water Pump Assembly

The Cummins 3073695 water pump assembly is a precision-engineered centrifugal coolant pump designed for the QSM11, ISM11, and M11 11-liter diesel engine platforms. It ensures forced circulation of coolant through the engine block, cylinder head, and radiator to maintain optimal operating temperatures under heavy load conditions. The unit features a cast iron housing, high-efficiency impeller, and sealed bearing assembly driven by the engine gear train. It supersedes and interchanges with OEM part numbers 4926553, 3803403, 4972853, 4299030, 4955707, 4972864, 4972863, 4972857, 2882144, 3800737, 3418015, and 3800954. This pump is a direct replacement for factory-installed units on Xi'an Cummins-produced engines used in heavy-duty trucks, hydraulic excavators, skid steer loaders, agricultural tractors, marine propulsion, and industrial generator sets. Installation requires standard hand tools and reuse or replacement of mounting gaskets and fasteners per service manual torque specifications.
