original Fuel Injector 10R-2977 for C11 C13 Diesel Engine Common Rail Injector Assembly Construction Machinery Spare Parts 13 10R-1274 239-4908 original new injector

The C13 Fuel Injector 10R-2977 is specifically engineered as a direct-fit replacement for C13 series engines, delivering precise fuel atomization and optimized combustion across industrial and mobile applications. Manufactured to OEM specification calibration standards, this electronic unit injector ensures high-pressure fuel delivery with an optimized spray pattern that supports clean combustion and stable engine performance. The precision-machined injector body is constructed from high strength alloy steel, providing exceptional durability, corrosion resistance, and long service life under severe operating conditions typically encountered in heavy-duty trucks, construction excavators, wheel loaders, bulldozers, mining trucks, industrial generator sets, and marine diesel engines.

This injector is fully interchangeable with authorized cross reference numbers 387-9433 and 249-0713, allowing seamless substitution across C13 ACERT, C13 Industrial Engine, C13 Generator Engine, C13 Marine Engine, and C13 Truck Engine platforms. Each unit undergoes 100% testing to verify spray pattern consistency, flow rate accuracy, and leak-free operation before shipment, guaranteeing reliable performance and direct compatibility with the original fuel injection system.

Proper maintenance significantly extends injector service life. Operators should use high-quality diesel fuel, replace fuel filters regularly, maintain clean fuel systems, and inspect fuel lines periodically. During installation, clean the injector seat thoroughly, replace seals and O-rings, follow torque specifications, bleed the fuel system, verify ECM operation, conduct a leak inspection, and perform an engine performance test. Routine injector diagnostics and monitoring of engine performance data help detect early symptoms such as hard starting, engine misfire, rough idle, excessive smoke, increased fuel consumption, loss of power, high emissions, and poor acceleration, ensuring the C13 engine continues to operate at peak efficiency throughout its service life.
