The Caterpillar 2645A751 is an original, electronically controlled high-pressure common rail diesel injector engineered for CAT C6 Series and Perkins 1100 Series diesel engines. Operating at rail pressures of up to 2000 bar, the injector delivers precise fuel atomization and accurate injection timing, achieving optimized combustion efficiency, lower fuel consumption, and reduced exhaust emissions under continuous heavy-duty operating conditions.
This injector is referenced across Caterpillar dealer networks and the diesel fuel injection aftermarket under multiple OEM and remanufactured numbers, including 2645A751, 320-0655, 3200655, 10R-7674, 10R7674, 10R-7671, and 10R7671, simplifying cross-reference and procurement for distributors, engine rebuilders, and remanufacturing centers. It is compatible with CAT C6.4 and C6.6 engines as well as Perkins 1106D-E66TA and 1104D-44TA industrial power engines, and is widely installed in CAT 320D, 320DL, 321D, 323D, and 324D excavators, diesel generator sets, and industrial power units.
In operation, the ECU calculates fuel demand according to engine load, RPM, and boost pressure, then signals the injector solenoid to open the needle valve for precisely metered combustion. For reliable service life, always clean fuel pipes before installation, use genuine sealing washers, perform ECU coding, and conduct injector balance testing. The 2645A751 serves construction, mining, agriculture, industrial power generation, and marine auxiliary applications worldwide.
