original 20R-2285 Diesel Fuel Injector for C15 C18 Excavator Engine Replacement for OEM 359-7434 20R-1304 374-0750 20R-2284 30R-0004 original new injector

Engineered as a direct OEM-grade replacement, the 20R-2285 Fuel Injector delivers precise, high-pressure diesel metering for C15, C15 ACERT, C16, 3406E, Industrial C15 and Marine C15 engines. Cross referenced to 10R-1273 and 253-0618, this remanufactured injector assembly is rebuilt to original specification, restoring factory-level fuel atomization, spray geometry and electronic response for demanding B2B fleet, industrial and marine operators worldwide.

The injector operates within an Electronic Unit Injection (EUI) system, receiving pressurized fuel and responding to ECM commands. A solenoid actuates the plunger, rapidly elevating internal pressure so the precision nozzle atomizes fuel into a fine mist for optimized combustion and lower exhaust emissions. Wear-resistant internal components, a corrosion-resistant body and calibrated flow rates support extended service life, improved power output, reduced fuel consumption and lower particulate emissions across heavy-duty highway trucks, mining trucks, excavators, wheel loaders, generator sets and marine vessels.

Unit 20R-2285 helps resolve common injector-related symptoms including hard start, no start, black or white smoke, engine knock, rough idle, reduced power, elevated fuel consumption and active fuel-system fault codes. For reliable installation, clean the injector bore, renew all seals and O-rings, follow torque specifications, bleed the fuel system and clear ECM codes. Serving construction, mining, transportation, marine, oil & gas and power generation markets globally.
