original 10R-1274 10R-1305 10R-2977 10R-3147 Fuel Injector for C11 C18 Excavator Attachment Truck new injector original new injector

Engineered as a direct-fit replacement for the C13 truck engine platform, the 10R-1274 electronic fuel injector is purpose-built to match the factory geometry, flow rate, and electrical signature of the original C13/C11 fuel system. Each unit is dimensioned at 14.8 inches in length and 3.0 inches in height, ensuring a precise match with the C13 injector bore and harness connector without modification. The injector integrates Advanced Combustion Emission Reduction Technology, supporting cleaner atomization, stable rail pressure response, and reduced exhaust emissions across heavy-duty duty cycles. As a Reman type component, it is recognized through multiple cross references including 249-0707, 239-4908, 232-1198, 10R-2977, and 249-2372, allowing seamless substitution across C13 and C11 service applications.

This injector is widely adopted in heavy-duty truck engine repair, full diesel engine rebuilds, and construction machinery service operations, including aftermarket-listed E345C and E345D excavators. It is equally suited to mining equipment maintenance, agricultural diesel service, fleet maintenance programs, and parts distribution or export trade channels. Available as a single unit or as a complete set of six injectors, the 10R-1274 supports full engine bank replacement when all cylinders share comparable service hours, restoring balanced fuel delivery across the entire C13 engine. Compatible OE and cross references include 10R-1274, 10R1274, CA10R1274, 249-0707, 2490707, 239-4908, 2394908, 232-1198, 2321198, 10R-2977, 10R2977, 249-2372, 2492372, 249-0708, 2490708, and 10R-1305, with C11/C13 engine compatibility.

Routine maintenance of the 10R-1274 injector centers on fuel quality control, scheduled fuel filter replacement, and regular water separator service to prevent contamination-related wear. Diagnostic procedures include return flow testing, cylinder cut-out testing, injector balance testing, fuel pressure verification, harness and seal inspection, and on-engine diagnostic scanning. Common fault symptoms such as hard starting, rough idle, black or white smoke, diesel knock, elevated fuel consumption, low power, engine misfire, fuel in oil, check engine light activation, excessive vibration, and external fuel leakage typically point to injector leakage, poor atomization, low injection quantity, over-fueling, electrical failure, or sealing failure. 140K2 compatibility is listed at low-to-medium confidence and should be verified before installation.
