The Perkins C13 C11 diesel fuel injector 10R-2977 is engineered as a direct OE replacement injector for Perkins C13 12.5L and C11 inline six-cylinder heavy-duty diesel engines. Built to original equipment specifications, this injector ensures correct fuel metering, stable atomization, and accurate injection timing for consistent combustion across all cylinders. A complete engine set normally requires six fuel injectors, and the part is available as a single unit or as a matched set to help maintain balanced fuel delivery in high-hour rebuild applications.
This injector is widely used on heavy-duty trucks, construction machinery, generator sets, industrial power units, mining equipment, off-highway machines, marine auxiliary engines, agricultural machinery, forestry equipment, and in engine rebuild workshops. Authorized cross reference numbers include 10R-2977, 10R2977, 1OR-2977, 1OR2977, 249-0708, 2490708, EX632977, 632977, 10R2977R, 10R-1274, 10R-1305, 10R-3147, and 253-1459, providing reliable interchangeability for fleet maintenance and replacement part sourcing.
Routine maintenance of clean diesel fuel, scheduled fuel filter replacement, water separator draining, correct engine oil quality, and a clean intake system helps maximize injector service life. Common failure symptoms include hard starting, rough idle, black or white smoke, misfire, high fuel consumption, low power, fuel knock, and active injector fault codes. Proper diagnosis should include a diagnostic scan, cylinder cut-out test, fuel pressure test, fuel filter inspection, connector inspection, and engine mechanical check before injector replacement is confirmed.
