original 2645A747 Common Rail Fuel Injector 320-0680 3200680 10R-7672 10R7672 32E61-00020 for C6.6 C4.4 Engine 320D E320D 323D Excavator Diesel Parts Replacement original new injector

Engineered to deliver OEM-grade performance for heavy-duty industrial diesel platforms, the 2645A747 Common Rail Fuel Injector is a precision-manufactured replacement component built for . C4.4, C6, C6.4, C6.6, C7, and C7.1 engines, as well as Perkins 1104D, 1106D, 1104D-E44T, 1104D-E44TA, and 1106D-E66TA power units. Each unit is cross-referenced with widely recognized numbers including 320-0680, 292-3780, 306-9380, 317-2300, 326-4700, 10R-7672, 10R-7671, 10R-7675, 32F61-00062, and 32F61-00060, ensuring seamless interchange in global service and rebuild programs.

The injector integrates high-precision nozzle geometry and tightly controlled solenoid response to achieve accurate fuel metering, optimized atomization, and efficient combustion under demanding load cycles. Field-proven benefits include improved fuel economy, better engine response, reduced exhaust smoke, extended service life, lower maintenance cost, stable idle operation, high-temperature resistance, and excellent heavy-duty reliability. It is engineered to help resolve common failure symptoms such as difficult starting, engine hesitation, loss of torque, increased fuel consumption, abnormal exhaust smoke, reduced acceleration, excessive engine noise, and recurring ECU fault codes.

Typical applications cover 320D, 323D, 324D, 325D, 329D, 330D excavators, 924H, 930H, 938H, 950H wheel loaders, 420E and 430E backhoe loaders, 120M–160M motor graders, plus generator sets, mining equipment, agricultural machinery, marine auxiliary engines, and off-highway diesel platforms. To maximize service life, use premium diesel fuel, avoid water contamination, replace fuel filters regularly, monitor ECU fault codes, and inspect rail pressure periodically.
