Engineered as a direct OEM replacement, the fuel injector 2645A751 is designed for Caterpillar C6.4 and C6.6 diesel engines, along with Perkins 1106D-E66TA and 1104D-44TA industrial power engines. The component is cross-referenced with 320-0655, 10R-7674, and 10R-7671, ensuring broad compatibility with CAT 320D, 320DL, 323D, 321D, and 324D excavators, diesel generator sets, and heavy construction and mining equipment. This high-pressure common rail injector operates at pressures up to 2000 Bar, delivering precise fuel atomization, accurate injection timing, and optimized combustion efficiency for dependable industrial performance.
The injection system relies on an electronically controlled solenoid mechanism. The engine ECU calculates fuel demand according to load, RPM, boost pressure, and operating conditions, then sends an electrical signal to the injector solenoid. The needle valve opens precisely to spray atomized fuel directly into the combustion chamber, supporting lower fuel consumption and reduced exhaust emissions across demanding duty cycles in excavators, generator sets, and industrial power units.
For proper installation, clean all fuel lines before fitting, avoid installing contaminated injectors, use genuine sealing washers, perform ECU coding after replacement, and conduct injector balance testing to confirm optimal operation.
