original 310-9067 3109067 Common Rail Diesel Fuel Injector Nozzle Assembly 2645A718 292-3780 10R-7672 10R-7669 for C6.6 Engine 320D M318D M322D Excavator Parts original new injector

Engineered for demanding industrial diesel applications, the 310-9067 Common Rail Fuel Injector delivers precise fuel atomization and high-pressure delivery calibrated to OEM specifications. This injector assembly serves as a direct replacement for OE numbers 310-9067, 326-4700, 328-2574, and 10R-7675, supporting C6 and C6.4 engine platforms deployed across construction, mining, power generation, and marine auxiliary systems. Each unit undergoes 100% flow testing to guarantee consistent injection quantity and spray pattern across the full operating range.

Constructed from hardened alloy steel with corrosion-resistant internal components, the injector integrates advanced internal hydraulic balancing technology and precision nozzle calibration for stable combustion, reduced fuel consumption, and extended operational lifespan. The heavy-duty internal architecture withstands continuous high-pressure cycling encountered in excavators, wheel loaders, backhoe loaders, diesel generator sets, and industrial power units. OEM-standard flow calibration ensures seamless integration with existing engine control strategies, minimizing correction values and supporting compliant emissions performance under variable load conditions.

For optimal service life, operators should use high-quality diesel fuel, replace fuel filters regularly, and avoid water contamination. Pre-installation checks include verifying injector part number, confirming engine serial number, inspecting fuel lines, and replacing sealing washers. Apply manufacturer torque specifications, bleed the fuel system, and complete injector coding where required. Recommended diagnostics include fuel pressure verification, injector leak-off testing, cylinder balance analysis, ECU fault code review, and spray pattern examination. Backed by a 12-month warranty.
