Perkins original  7C-9578 Common Rail Fuel Injector Assembly for 3512A 3500A 3508 3512 3516 Engine Diesel Fuel Injector Parts 10R3053 7E-3381 9Y-0052 original new injector

Engineered specifically for the Perkins 3512A and related 3512C, 3516B, and 3516C diesel platforms, the 7C-9578 fuel injector delivers consistent atomization and precise fuel metering under demanding load conditions. Manufactured from high-grade alloy steel with anti-corrosion coating, it withstands operating pressures up to 1,800–2,000 bar and temperatures ranging from -40°C to 120°C, making it equally suited to marine engine rooms, mining sites, and stationary power generation facilities.

The injector is produced to OEM-grade tolerances, ensuring a direct flange-mounted fit without modification and reliable sealing at the recommended torque of 35–40 Nm. Its multi-hole precision nozzle promotes enhanced combustion efficiency, reducing particulate output and NOx emissions while supporting stable performance across the 1,800–2,100 rpm range. The component is fully interchangeable with cross references 7C9579, 9N-9352, and 6I-3558, providing fleet operators with a flexible replacement option across heavy equipment such as the Perkins 352C excavator, D11 bulldozer, and 777 mining truck.

Routine inspection every 500 operating hours, combined with clean diesel fuel and proper filtration, helps maintain spray pattern integrity and prevents nozzle clogging. Each unit is backed by a 12-month industrial warranty and certified to ISO 9001, CE, and RoHS standards, giving maintenance teams confidence in long-term reliability for both onboard marine generators and land-based industrial power plants.
