Aftercooler Large capacity integral aftercoolers are supplied with cooling water separate from the engine jacket. This provides cooler, denser intake air for more complete combustion and reduced engine stresses for longer life and low exhaust emissions.

Cooling System A two pump, two loop system must be employed; i.e. the engine jacket is cooled by one radiator or heat exchanger and the aftercoolers are cooled by a separate radiator or heat exchanger. Both cooling systems are independent of each other. The jacket water pump is supplied engine mounted from the rear of the gear cover. The aftercooler water pump is customer selectable and can be provided mounted on the front of the gear cover. Cummins provides conventional water inlet and outlet connections for the jacket system. Aftercooler water pump inlet and aftercooler core outlet connections are provided for customer use and ease of plumbing on the aftercooler system.

Lubrication Large capacity integral gear driven pump provides pressure lubrication to all bearings and provides supply for piston cooling. Cummins supplied large capacity oil pans are recommended for Prime and Continuous Power applications.

Pistons Pistons are dual Ni-resist, aluminum alloy, ground and shaped to compensate for thermal expansion which assures a precise fit at all normal operating temperatures. Oil cooled for rapid heat dissipation. Two compression rings and one oil ring. Utilizes offset piston pin for reduced susceptibility to liner cavitation.
