Perkins original Perkins 2645A747 Common Rail Fuel Injector 10R-7672 320-0680 for C6.6 C4.4 320D Excavator Diesel new injector original new injector

The 2645A747 fuel injector is a precision-engineered common rail component designed for Perkins C4.4, C6, C6.4, C6.6, C7, and C7.1 diesel engines, including the 1104D, 1104D-E44T, 1104D-E44TA, 1106D, and 1106D-E66TA models. It is compatible with excavators such as 320D, 323D, and 330D, wheel loaders including 924H, 930H, and 938H, backhoe loaders from the 420E through 450E series, and motor graders like the 120M, 140M, and 160M, making it suitable for construction, mining, agricultural, generator, marine auxiliary, and off-highway applications.

This electronically controlled injector features an ECU-calibrated high-pressure common rail design that precisely meters fuel quantity based on engine speed, load, boost pressure, coolant temperature, and throttle position. The precision-machined nozzle holes deliver ultra-fine fuel atomization for optimized combustion, resulting in improved fuel economy, better engine response, reduced exhaust smoke, stable idle operation, and lower overall maintenance costs across heavy-duty operating cycles.

Interchangeable with cross numbers 2645A718, 2645A734, 2645A737, 2645A738, 2645A746, 2645A749, 2645A751 through 2645A757, 320-0680, 292-3780, 306-9380, 317-2300, 326-4700, 10R-7672, 10R-7671, 10R-7675, 32F61-00062, and 32F61-00060, the 2645A747 provides OEM-equivalent fit and performance. Built with high-temperature resistant materials and designed for extended service life, it reduces emissions while maintaining reliable power output in demanding industrial environments.
