original Fuel Injector 249-0707 Common Rail Assembly for C11 C13 Excavator Engine Part 10R-1305 249-0712 10R-2977 Replacement for OEM new original new injector

The 249-0707 common rail fuel injector is specifically engineered for the C11 engine platform, delivering OEM-equivalent fuel delivery across a broad range of industrial and mobile applications. Built with high-strength alloy steel and a precision-engineered nozzle, this injector provides consistent high-pressure fuel atomization that supports stable combustion in demanding operating environments. It is designed as a direct replacement for the original C11 injector, matching factory fuel calibration specifications to help maintain rated engine performance without requiring system modification.

This injector assembly is compatible with multiple C11 engine configurations, including the C11 ACERT, Industrial Power C11, Marine C11 Propulsion, Generator Set C11, and Stationary Industrial C11 variants. It serves construction equipment, mining machinery, marine engines, generator sets, industrial power systems, industrial pump systems, heavy duty truck applications, oil and gas equipment, and power generation systems. Its robust construction and corrosion-resistant materials make it well suited for continuous-duty operation in harsh field conditions, supporting long service life even under high load and extended runtime cycles.

Proper installation and routine maintenance are essential to achieving reliable injector performance. Operators should use high-quality diesel fuel, replace fuel filters at recommended intervals, and keep fuel storage systems free from water contamination. Before installation, injector ports and seat surfaces should be cleaned and inspected, and any damaged seals replaced immediately. Manufacturer-recommended torque values must be applied, followed by leak testing, fuel pressure inspection, and post-installation engine performance verification. Common fault indicators such as hard starting, black or white smoke, power loss, high fuel consumption, or rough engine operation should be evaluated through injector diagnostics during major service intervals to ensure continued reliable operation of the C11 engine.
