Perkins original Perkins 7C-4175 Diesel Engine Fuel Injector Common Rail Injector Assembly for 3508 3512 3516 3500A Engine original new injector

Engineered to meet the rigorous demands of heavy-duty industrial operations, the Perkins 7C-4175 fuel injector delivers consistent and reliable fuel delivery for Perkins 3500 Series engines, including the 3512A, 3512B, 3516, and 3508 models. Manufactured to OEM precision standards, this injector is built from hardened alloy steel, providing excellent corrosion resistance and a long service life under continuous high-load operation. Each unit is factory calibrated to ensure accurate fuel spray patterns, which directly supports optimized combustion efficiency, reduced smoke and emissions, and improved overall fuel economy.

With extensive cross-reference compatibility—including 0R-2924, 6I-4356, 7C-0345, OR-2411, 4P-9075, 4P-9076, 4P-9077, 111-3718, 127-8220, and 61-3075—this injector serves as a versatile direct replacement for power generation, marine propulsion, mining, construction, and oil & gas power systems. It maintains steady engine power output across all load conditions, making it a dependable choice for critical industrial equipment where downtime is not an option.

Proper installation and maintenance are essential to achieving full injector performance. Operators should clean the fuel system prior to installation, replace all seals, o-rings, and gaskets, and apply OEM-specified torque values. Routine inspection intervals are recommended at every 1000 hours, with full system cleaning at 3000 hours and overhaul at 6000 hours. Fuel filter checks every 250 hours help prevent flow restrictions that could lead to hard starting, smoke, power loss, or increased fuel consumption.
