original 320-0680 Common Rail Fuel Injector 10R-7672 2645A747 Diesel Engine Injector for C4.4 C6.6 320D 323D Excavator Machinery Parts original new injector

Engineered for heavy-duty diesel performance, this common rail fuel injector 320-0680 is manufactured to OEM precision standards and serves as a direct replacement for cross references 10R-7672, 292-3780, 306-9380, 2645A747, 2645A734, 2645A718, and 2645A709. Designed to fit C4.4, C6, and C6.6 diesel engines, this injector is a core fuel delivery component in excavators, wheel loaders, generator sets, and marine power systems operating under demanding load conditions.

The injector features multi-hole nozzle technology delivering superior atomization, precise fuel metering, and improved combustion efficiency across the entire RPM range. Additional cross references include 2645A747R, 282-0490, 382-0480, 295-9130, 775810, 747379, and 786458 for broad interchangeability. High pressure resistance, corrosion-resistant materials, and rigorous factory calibration ensure long service life, stable idle performance, reduced exhaust emissions, and lower fuel consumption. It is compatible with equipment including 320D, 323D, M313D, M315D, M316D, M318D, and M322D machines.

For optimal service life, use ultra-clean diesel fuel, replace fuel filters regularly, prevent water contamination, and monitor fuel rail pressure. Installation requires new sealing washers, clean fuel lines, and adherence to service manual procedures, with fuel system calibration performed when required. Recommended diagnostics include injector return flow test, cylinder balance test, fuel rail pressure test, electronic fault code scan, injector bench test, and spray pattern analysis for accurate fault identification.
