Caterpillar original Common Rail Diesel Fuel Injector 282-0490 292-3780 306-9380 10R7672 Replacement for Caterpillar Excavator OEM Parts, for heavy duty diesel engine application original new injector

The Caterpillar 282-0490 is an industrial-grade high-pressure diesel fuel injector manufactured to meet strict OEM standards for heavy-duty diesel engine operations. As a precision metering component, it receives high-pressure diesel from the engine’s high-pressure pump, opens at exact timings commanded by the ECU, and atomizes fuel through its precision nozzle before injecting it into the combustion chamber. This optimized atomization supports complete combustion, delivering improved fuel efficiency, reduced emissions, and consistent power output for compatible CAT C6 and C6.6 inline 6 diesel engines.

Every 282-0490 injector features a precision-machined nozzle, hardened internal components, and corrosion-resistant construction, with full testing to ensure OEM-equivalent performance and industrial durability. It supports multiple cross-reference numbers, including reman 10R-7668/10R7668, service replacement 276-8290/2768290, replacements 289-7501, 293-9590, 321-0990, and Perkins cross-ref 2645A709. It fits CAT equipment including 938H, 963D, 120M, 12M, C6 series excavators, and C6.6 generator sets, and cross-fits Perkins 1106D-E66TA engines in aftermarket use.

For reliable performance, installers must follow CAT torque specs, clean the fuel system pre-installation, conduct leak testing, and complete required ECU calibration and test runs. Scheduled maintenance includes filter checks every 500 hours, fuel system inspections every 1000 hours, injector testing every 2000 hours, and full fuel system evaluations every 3000 hours. Backed by available warranty and global distribution, it serves construction, mining, agriculture, power generation, marine, and stationary industrial applications, reducing unplanned downtime and extending equipment service life.
