original 306-9380 Common Rail Diesel Fuel Injector for C6.6 C6.4 C4.4 C4.2 1104 Engine 320D 312D 315D Excavator Parts 10R-7672 320-0690 2645A749 original new injector

Engineered for demanding industrial diesel applications, the 306-9380 Fuel Injector delivers OEM-grade performance across the C6 engine family, including C6.4 and C6.6 platforms. Cross-referenced with 10R-7225 and 326-6708, this injector is a direct replacement solution for excavators, loaders, dozers, generator sets, and industrial power units operating in construction, mining, agricultural, and heavy industrial environments worldwide.

The injector features precision nozzle technology for exact spray patterns, optimized fuel atomization, and improved combustion efficiency. Built from corrosion and wear-resistant materials, it withstands high-pressure operation between 1200–1600 bar and delivers reliable performance under extreme temperature and load conditions. With an installation torque of 40–50 Nm and a 2-pin connector, it integrates seamlessly with common rail, solenoid, and mechanical fuel systems on engines rated 120–220 HP and 4.4–6.6L displacement. Enhanced atomization contributes to improved fuel economy and low-emission performance in line with international standards, while extended service intervals reduce total maintenance costs.

Recommended maintenance includes visual inspection every 250 hours, fuel system checks every 500 hours, performance testing at 1000 hours, and calibration checks every 4000 hours, with replacement evaluation at 6000 hours. Ideal for equipment fleets including 308E–329D excavators and 906M–962H loaders, this injector supports global operations across North America, Europe, Asia, Africa, and Australia.
