original 291-5911 Diesel Engine Fuel Injector for C18 C15 Excavator Loader 772 772G 988 Replacement OEM 10R-7230 253-0616 10R-3265 276-8307 Injectors original new injector

Engineered for demanding heavy-duty diesel operations, the 291-5911 Fuel Injector delivers precision fuel metering and reliable high-pressure atomization for C18 series engines. Fully interchangeable with cross reference 10R-7224, this injector assembly serves as a direct OEM replacement designed for global industrial markets including mining, construction, marine propulsion, oilfield services, and prime or standby power generation. Every unit is produced with micron-level machining technology to guarantee consistent fuel delivery, improved combustion efficiency, and stable engine performance across a wide range of load conditions.

The injector integrates advanced surface treatment for corrosion resistance and enhanced thermal stability, ensuring dimensional accuracy even under extreme operating temperatures. Wear-resistant internal components extend service life, while the electronic control interface supports accurate injection timing for reduced emissions, increased power output, and improved fuel economy. Applicable to C18, C18 ACERT, Industrial C18, Marine C18, Generator C18, Petroleum C18, and Power Unit C18 platforms, it fits seamlessly into haul trucks, excavators, wheel loaders, dozers, generator sets, tugboats, drilling rigs, and industrial pump drives without modification.

Installation follows standard service procedures: verify the part, clean the fuel system, replace sealing washers, torque fasteners to specification, prime the system, and inspect for leaks. Recommended diagnostics include fuel pressure testing, injector balance testing, ECM scanning, and spray pattern analysis. Backed by a 12-month warranty.
