original 239-4907 Common Rail Diesel Fuel Injector for C11 C13 Excavator Engine 2394907 249-0712 232-1198 10R-1305 Aftermarket Replacement original new injector

Engineered for demanding heavy-duty operations, the 239-4907 Fuel Injector is a precision-built diesel injection component designed as a direct replacement for the C11 engine platform. Cross-referenced under OE number 2394907, this injector assembly delivers OEM-level injection calibration and micron-level fuel metering to ensure consistent combustion performance across C11, C11 ACERT, and dedicated C11 Industrial, Generator, Marine, Construction, Mining, and Oilfield engine variants. Every unit is manufactured from hardened alloy steel to withstand extreme pressures within high-pressure diesel injection systems.

Key engineering features include precision-machined internal components, optimized spray atomization technology, corrosion-resistant construction, and industrial-grade sealing systems for reliable long-term operation. Installed at the cylinder head fuel injector port, the 239-4907 supports stable fuel delivery under continuous load conditions and is suitable for excavators, wheel loaders, mining trucks, underground mining machinery, diesel generator sets, marine propulsion and auxiliary engines, drilling and fracturing equipment, compressor systems, and other heavy industrial power units serving global B2B markets.

Recommended service practices include the use of clean diesel fuel, regular fuel filter replacement, fuel pressure monitoring, prevention of water contamination, and periodic injector testing per OEM intervals. For installation, replace all seals and O-rings, follow specified torque values, verify fuel line cleanliness, and perform leak testing. Diagnostic support covers cylinder cut-out testing, injector balance verification, nozzle spray pattern inspection, ECM fault code review, and fuel return flow analysis.
