Caterpillar original Diesel Fuel Injector 280-0574 Replacement for OEM, Cross Reference 253-0615, 254-4183, for Caterpillar C15 C18 Excavator Construction Machinery with 10R-8989 original new injector

The CAT 280-0574 diesel fuel injector is a precision-engineered Electronic Unit Injector (EUI) purpose-built for Caterpillar C15 engine platforms, with full compatibility across C15 ACERT, SDP, MXS, BXS, NXS, industrial, marine and generator C15 variants, plus selected 3406E configurations. Manufactured strictly per OEM specifications from hardened alloy steel, it is available in new or remanufactured options to suit diverse replacement needs and budgets, with verified cross-part numbers for convenient part lookup and matching.

Controlled by the engine’s ECM, the injector adjusts fuel quantity and injection timing in real time based on load, RPM, temperature and emissions requirements, using its integrated plunger to generate extremely high injection pressure. Precision-machined nozzle holes atomize fuel into microscopic droplets for optimized combustion, delivering benefits including improved fuel economy, stable high power output, lower emissions, reduced smoke, faster throttle response and extended engine service life.

Built to withstand harsh heavy-duty operating conditions, the 280-0574 supports equipment across on-highway transportation, construction, mining, marine, power generation, oil & gas and agricultural sectors. It comes with a 12-month warranty and is offered with neutral or OEM-customized packaging, delivering stable, long-term performance even in the most demanding industrial work environments.
