This C13 C11 diesel fuel injector is engineered as a direct-fit replacement for the C13 12.5L and C11 heavy-duty diesel engines. The injector carries the authorized OE number 10R-2977 and supports multiple cross references including 10R2977, 1OR-2977, 1OR2977, 249-0708, 2490708, EX632977, 632977, 10R2977R, 10R-1274, 10R-1305, 10R-3147, and 253-1459, which makes part identification straightforward for distributors, fleet operators, and engine rebuild workshops.

The unit operates within the HEUI / EUI electronically controlled injection system to deliver accurate fuel metering, stable atomization, and precise injection timing. It is designed for controlled spray pattern, balanced cylinder delivery, and dependable performance under high-load diesel conditions. The injector can be supplied individually or as a complete matched set of six units for a full C13 engine rebuild, and it is commonly fitted to heavy-duty trucks, construction machinery, generator sets, mining equipment, off-highway machines, marine auxiliary engines, and agricultural and forestry equipment.

Routine maintenance should include the use of clean diesel fuel, scheduled fuel filter replacement, water separator draining, correct engine oil quality, and a clean intake system. Typical symptoms of a worn injector such as hard starting, rough idle, black or white smoke, misfire, high fuel consumption, low power, fuel knock, or active fault codes should be confirmed through diagnostic scan, cylinder cut-out test, fuel pressure test, and connector inspection before replacement.
