Caterpillar 2054964 Aftercooler Assembly

The Caterpillar 2054964 aftercooler core assembly functions as a charge air cooler within the engine intake system. It reduces compressed air temperature from the turbocharger before entering the combustion chambers of the 3126B diesel engine, improving air density and combustion efficiency while lowering NOx emissions. Constructed with a bar-and-plate aluminum core design for high thermal transfer efficiency and structural integrity under high boost pressure cycles. The unit features integrated header tanks and mounting flanges designed for direct installation on Caterpillar 322C and 325C hydraulic excavator platforms. This component meets OEM dimensional and performance standards for replacement in heavy construction machinery applications.
