Caterpillar original 10R-7672 Common Rail Diesel Fuel Injector for 320D C4.4 C6.6 Engine 320-0677 3200677 2645A746 10R-7671 2645A738 3069377 new original new injector

The Caterpillar C6 fuel injector 10R-7672 is an original OEM-specification diesel injection component engineered for CAT C6, C6.4, and C6.6 diesel engines. Manufactured using precision-machined alloy steel components and advanced nozzle calibration technology, each unit is calibrated according to Caterpillar factory specifications to ensure stable injection patterns, accurate fuel metering, and consistent combustion performance across varying load conditions. Cross-referenced with part numbers 10R7672, 326-1641, 3261641, 10R-7656, and 10R7656, this injector provides a direct-fit replacement solution for heavy-duty industrial applications.

Designed for demanding operating environments, the 10R-7672 injector features high-pressure capability to support modern direct injection diesel systems, heavy-duty construction for extended service life, and corrosion-resistant internal surfaces that protect against fuel contamination. It maintains proper fuel delivery under heavy loads, enhancing engine power output and reducing unnecessary fuel consumption. The component supports cleaner combustion processes, helping operators comply with lower emission targets while maintaining long maintenance intervals in the field.

This Caterpillar C6 injector is widely used in crawler excavators, hydraulic excavators, wheel loaders, backhoe loaders, industrial generators, standby and prime power systems, marine propulsion and auxiliary engines, mining trucks, oilfield equipment, road construction machinery, agricultural power units, forestry equipment, and water pump drive systems. Common fault symptoms addressed by replacement include black exhaust smoke caused by carbon accumulation or poor atomization, white exhaust smoke from injector leakage, and engine power reduction linked to fuel starvation or rail pressure issues, all of which can be resolved through proper injector inspection and replacement.
