Perkins original Perkins original Perkins 0R-8465 Mechanical Diesel Fuel Injector Pump Assembly for 3116 3406B Engine 320B 325B Excavator Replacement for OEM new injector original new injector

The Perkins 3116 Fuel Injector 0R-8465 is a precision-engineered fuel metering component designed for the Perkins 3116 and 3116B series diesel engines. Manufactured to micron-level tolerances, this injector delivers consistent fuel volume metering, elevated injection pressure, finely atomized diesel spray patterns, and precisely controlled injection timing. The result is optimized combustion efficiency, reduced fuel consumption, lower exhaust emissions, enhanced horsepower output, and extended engine service life across demanding operating cycles.

Constructed with specialized heat-resistant and corrosion-resistant metallurgy, the 0R-8465 injector withstands continuous operation in high ambient temperature environments and resists degradation from sulfur contamination, water ingress, and fuel quality variations. OEM 127-8228 equivalents include cross references 107-1233, 4P-2233, OR-4103, OR-4370, 127-8216, 127-8230, 162-0212, 0R-8473, 0R-8479, 0R-8684, and 101-8673, ensuring broad compatibility for replacement and overhaul requirements.

This injector is widely deployed across excavators including Perkins 325, 325L, 322L, and 320 series, wheel loaders such as Perkins 938F, 950F, and 950G, articulated trucks including Perkins D250E and D300E, as well as commercial vessels, fishing boats, work boats, patrol boats, marine generator sets, industrial power units, and emergency or prime power installations. Installation follows a standardized ten-step procedure covering battery disconnection, bore cleaning, seat inspection, sealing washer replacement, torque application to Perkins specification, fuel line reconnection, system priming, and leak verification.
