Unplanned downtime on CAT C6-powered machines is frequently traced to inconsistent fuel delivery—and the 10R-7674 diesel fuel injector is built to eliminate exactly that. As an OEM-quality replacement injector for Caterpillar C6 engines, this assembly restores precise fuel metering and clean atomization, supporting stable combustion, smooth power output, and reliable starting. It directly interchanges with 10R7674, 326-4700, 320-0680, 3264700, 3200680, and 2645A749, making part identification straightforward across mixed equipment fleets.

Manufactured to original equipment standards, the 10R-7674 common rail fuel injector nozzle assembly is engineered for the high-pressure demands of Caterpillar diesel fuel systems. OEM-grade materials and tight machining tolerances deliver consistent injection performance through long, heavy-duty service intervals, while the direct-fit design matches original mounting and connection points—no modification needed at installation. For maintenance teams and parts buyers, that translates into shorter service time, predictable fitment, and fewer cross-reference errors when sourcing replacements.

This injector serves CAT C6 engines across construction, mining, and power generation applications, including excavators, loaders, and industrial generator sets. With multiple superseded and alternative numbers consolidated into one replacement unit, the 10R-7674 is a practical stock item for both scheduled maintenance and urgent repairs.
