Perkins original 191-3005 Common Rail Fuel Injector Assembly for 3412 Diesel Engine 20R-4148 174-7527 198-4752 198-7912 198-6877  original new injector

The Perkins 191-3005 fuel injector is engineered as a direct OEM-equivalent replacement for the Perkins 3412 engine platform, covering the 3412, 3412B, 3412C, and 3412 DITA variants. It is designed for diesel generator sets, marine propulsion engines, and stationary power modules where consistent fuel delivery is critical. Cross-referenced with part numbers 0R-8477, 10R-0955, 170-5187, 4P-9830, and 7W-7032, this injector fits seamlessly into existing fuel injection systems used across power generation, marine, mining, and oil and gas applications.

Manufactured from precision-hardened alloy steel, the 191-3005 injector delivers accurate fuel metering, superior spray atomization, and stable high-pressure performance. These characteristics support improved combustion efficiency, reduced fuel consumption, lower exhaust emissions, and increased engine output. The corrosion-resistant construction enhances service life and minimizes carbon buildup, addressing common issues such as hard starting, rough idle, excessive smoke, and power loss in demanding operating environments.

Each unit is packed to export standards and inspected for dimensional accuracy and flow performance before shipment. Installation should follow Perkins service manual procedures, including replacement of sealing washers, verification of fuel line cleanliness, proper torque application, and post-installation leak testing. Routine preventive maintenance, including clean diesel fuel usage, regular filter replacement, and injector balance testing, helps sustain reliable engine operation over extended service intervals.
