original 10R-7672 Common Rail Diesel Fuel Injector for Excavator 320D Engine C4.4 C6.6 Replacement for OEM 3200677 320-0677 2645A746 10R-7671 2645A738 original new injector

Engineered for demanding industrial service, the 10R-7672 diesel fuel injector is a precision-calibrated common rail injection component designed for C6, C6.4, and C6.6 inline 6-cylinder turbocharged diesel engines. Cross-referenced with 3261641 and 10R7656, this injector assembly delivers reliable fuel atomization for excavators, wheel loaders, backhoe loaders, industrial generators, marine propulsion engines, mining equipment, and agricultural machinery operating under sustained heavy loads.

Built with heavy-duty construction and corrosion-resistant components, the 10R-7672 injector ensures precision fuel metering under fluctuating load conditions and supports the elevated pressures required by modern direct injection systems. OEM calibration guarantees a stable injection pattern for consistent combustion, improved fuel efficiency, enhanced engine power delivery, and reduced exhaust emissions. Its extended service life is engineered to minimize downtime in mission-critical applications such as prime power systems, standby generators, oilfield equipment, and compressor drive assemblies. Each unit is manufactured to meet strict quality controls, providing a dependable replacement for original 10R7656 and 3261641 injectors.

Installation requires disconnecting the battery, relieving fuel system pressure, removing fuel lines and retaining hardware, cleaning the injector bore, fitting new seals, and torquing to specification followed by leak inspection and engine diagnostics. Recommended maintenance includes using clean diesel fuel, replacing fuel filters regularly, avoiding water contamination, and performing periodic injector balance testing. Troubleshooting for black or white exhaust smoke and power reduction should include injector inspection, spray pattern verification, and fuel pressure testing.
