Engineered as a direct replacement solution for the C15 diesel platform, the 280-0574 Electronic Unit Injector delivers precision fuel metering and high-pressure injection performance for demanding industrial applications. Manufactured from hardened alloy steel, this injector assembly is fully interchangeable with cross references 10R1273, 253-0616, 3282574, 3879433, and 20R2053, offering B2B buyers a reliable procurement option for fleet maintenance, MRO operations, and OEM aftermarket distribution channels worldwide.

This injector is compatible with C15, C15 ACERT, C15 SDP, C15 MXS, C15 BXS, C15 NXS, Industrial C15, Marine C15, Generator C15, and selected 3406E configurations. Applications span heavy duty trucks, mining trucks, excavators, wheel loaders, generator sets, marine propulsion vessels, oil & gas equipment, agricultural machinery, and industrial power units. Key benefits include improved fuel economy, higher power output, lower emissions, reduced smoke, faster throttle response, and extended engine service life. Corrosion resistance and industrial-grade durability ensure long operational lifespan under continuous heavy load conditions.

Installation requires cleaning the injector bore, replacing sealing washers, lubricating O-rings, applying calibrated torque, verifying ECM calibration, and performing an injector balance test. Recommended maintenance includes clean diesel fuel usage, regular fuel filter replacement, water separator draining, and periodic injector diagnostics. Common troubleshooting indicators—hard starting, white or black smoke, power loss, and rough idle—can be effectively resolved with this replacement.
