original 10R-2977 Common Rail Fuel Injector Assembly for C11 C13 Engine Diesel Injector Construction Machinery Parts Replacement for OEM 249-0713 original new injector

Engineered as a direct OEM-specification replacement, the 10R-2977 Fuel Injector is a precision electronic unit injector designed for C13 diesel engines operating across demanding industrial, on-highway, and marine environments. Manufactured from high strength alloy steel and calibrated to original equipment tolerances, this injector cross-references OE numbers 10R-2977, 387-9433, and 249-0713, ensuring seamless interchangeability for fleet operators, service workshops, and industrial maintenance teams sourcing dependable diesel fuel system components.

The injector features a precision-machined body, high-pressure fuel delivery, and an optimized spray pattern that promotes complete atomization inside the combustion chamber. Benefits include improved combustion efficiency, reduced fuel consumption, lower particulate emissions, increased engine power, enhanced cold starting performance, and better throttle response. Its heavy-duty construction and corrosion resistance deliver long service life under severe operating conditions typical of C13 ACERT industrial engines, C13 generator sets, C13 marine propulsion units, and C13 on-highway trucks used in construction, mining, transportation, oil & gas, agricultural, and power generation sectors.

Installation requires thorough cleaning of the injector seat, replacement of seals and O-rings, adherence to torque specifications, fuel system bleeding, ECM verification, leak inspection, and a performance test. For sustained reliability, use high-quality diesel fuel, replace fuel filters regularly, perform periodic injector diagnostics, and monitor engine data. This injector effectively resolves hard starting, misfire, rough idle, excessive smoke, power loss, and poor acceleration.
