Caterpillar original Common Rail Fuel Injector Cross Reference 10R-7671, Diesel Engine Fuel Injector 320-0680 Replacement for 320-0690, C4.4 C6.6 Engine, 10R-7672 for Excavator original new injector

For fleet managers, equipment operators and maintenance teams relying on Caterpillar diesel power systems, the CAT 320-0680 common rail fuel injector is a precision-engineered component built to deliver consistent, accurate fuel delivery. Operating within the high-pressure common rail system, it meters exact fuel quantities and sprays finely atomized fuel directly into the combustion chamber at ultra-high pressure, optimizing combustion efficiency, reducing fuel consumption and exhaust emissions, while supporting stable idling and improved engine power output.

As an OEM-equivalent replacement part, the 320-0680 injector is cross-referenced with a comprehensive set of valid CAT and Perkins part numbers, and is engineered to fit all Caterpillar C4.4, C6 and C6.6 engine variants, including industrial, generator and marine C6 configurations. It is compatible with a wide range of CAT equipment such as 320D, 323D and M-series excavators, supporting use cases across construction, mining, power generation, marine propulsion and industrial power sectors worldwide.

Manufactured to strict OEM-level calibration and durability standards, the injector features multi-hole nozzle technology, high pressure resistance, corrosion resistance and heavy-duty reliability for extended service life in harsh operating conditions. It comes with a 12-month warranty, and aligns with official Caterpillar installation and maintenance specifications, with standardized diagnostic protocols available to streamline troubleshooting and minimize unplanned equipment downtime.
