Caterpillar original C6.6 Engine Fuel Injector 310-9067, Diesel Common Rail Injector Assy, Cross Reference 320-0680, 10R-7669, 306-9380, for Excavator 320D M318D M322D original new injector

The Caterpillar 310-9067 fuel injector is a precision-engineered high-pressure diesel injection component designed for CAT C6 engine platforms, compatible with C6.4 and CAT industrial, construction, and power generation C6 variants. Manufactured to meet or exceed OEM specifications, every unit is 100% flow tested, featuring hardened alloy steel construction, internal hydraulic balancing, and calibrated nozzles to deliver accurate atomization, optimized combustion, higher power output, reduced fuel consumption, and lower emissions for heavy-duty operation.

This new OEM-equivalent injector uses 310-9067 (3109067) as its core OE number, with verified cross references to 326-4700 (3264700), 328-2574 (3282574), and 10R-7675 (10R7675). It supports equipment across sectors: excavators, wheel loaders, backhoe loaders and mining equipment for construction; diesel generator sets for power generation; plus agricultural equipment, industrial power units, and marine auxiliary engines. Fitment must be verified via engine serial number before ordering, as cross references vary by market, emission level and arrangement.

Built for harsh industrial environments, the injector uses corrosion-resistant materials and heavy-duty internal structures to deliver stable performance and extended service life. It is packed in industrial export-grade packaging to prevent transit damage, and comes with a 12-month warranty for B2B buyers. Recommended installation practices include pre-install checks, torque adherence, system air bleeding, and leak testing, while high-quality fuel and regular filter changes maximize operational lifespan.
