original 7C-4175 Common Rail Injector Assembly 111-3718 0R-8338 7E-3383 0R-2925 for 3500A 3508 Diesel Engine new injector original new injector

The 7C-4175 fuel injector is specifically engineered for the 3500 Series engines, including the 3512A, 3512B, 3516, and 3508 models. Designed as a direct OEM replacement, this mechanical injector meets factory calibration specifications to ensure precise fuel metering and accurate spray pattern delivery. The hardened alloy steel construction provides exceptional wear resistance and long service life under the demanding operating conditions encountered in power generation, marine propulsion, mining, construction, and oil & gas applications.

Each 7C-4175 injector carries cross-reference compatibility with 0R-2924, 6I-4356, 7C-0345, OR-2411, 4P-9075, 4P-9076, 4P-9077, 111-3718, 127-8220, and 61-3075, allowing flexible installation across the 3512A platform and related 3500 Series variants. Optimized atomization promotes complete combustion, reducing smoke and harmful emissions while improving fuel economy and maintaining steady power output across all load ranges. The corrosion-resistant design supports reliable operation in humid marine environments and dusty industrial sites.

Prior to installation, the fuel system should be thoroughly cleaned, all seals, O-rings, and gaskets replaced, and OEM torque values strictly followed. After fitment, injector calibration must be verified to confirm proper operation. Recommended maintenance includes fuel filter checks every 250 hours, injector inspection at 1000 hours, system cleaning at 3000 hours, and a full overhaul at 6000 hours to sustain engine reliability and performance throughout the service interval.
