original 116-8805 Diesel Fuel Injector for C12 3176 3196 E345B Excavator Engine Part 116-8866 1660149 Replacement for OEM new original new injector

The C12 fuel injector GP is engineered specifically as a direct replacement for the C12 / C-12 diesel engine platform, matching the original injector group configuration used across heavy-duty truck, excavator, marine, and generator set applications. With primary reference 116-8805 and extensive cross coverage of 0R-9530, 166-0149, 123-0469, 116-5425, 161-1708, 229-5918, 10R-1814, 10R-1258, and 212-3468, this injector supports a wide range of C12 engine arrangements, though final compatibility should always be confirmed against the engine serial number, ECM calibration, and the originally fitted injector number before installation.

Built for the demanding operating conditions of the C12, the injector delivers precise fuel metering, accurate injection timing, and consistent atomization, ensuring balanced cylinder-to-cylinder combustion and stable performance under heavy load. Heavy-duty construction and wear-resistant internal components provide the durability required for long service intervals in on-highway trucks, construction machinery, marine propulsion, and stationary generator applications, while sealed fuel passages prevent leakage and help maintain original engine efficiency throughout the replacement cycle.

For optimal reliability, clean diesel fuel, scheduled fuel filter replacement, regular water separator draining, and clean fuel tank storage are strongly recommended. After installation, technicians should perform fuel pressure testing, injector balance testing, cylinder cut-out testing, ECM code reading, and verify installation torque and cleanliness, replacing injectors as a matched set when required to keep the C12 engine operating at factory performance levels.
