original 0R-8465 Diesel Fuel Injector Pump Assembly for 3116 3406B Engine Excavator 320B 325B 322B 446B 200B Construction Machinery Replacement OEM 127-8218 original new injector

Engineered as a critical fuel delivery component for 3116 Series diesel engines, the 0R-8465 fuel injector delivers OEM-grade performance across demanding industrial, construction, and marine operating environments. This injector is fully cross-referenced with 127-8228, 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 interchangeability for global B2B procurement and aftermarket fleet maintenance programs.

The 0R-8465 injector precisely meters fuel volume, increases fuel pressure, atomizes diesel fuel, controls injection timing, and promotes complete combustion within 3116 and 3116B engines. Machined to micron-level tolerances, it delivers higher combustion efficiency, reduced fuel consumption, lower exhaust emissions, improved horsepower, and extended engine service life. Specialized metallurgy provides heat resistance for mining, marine, and high ambient temperature zones, while corrosion-resistant construction protects against sulfur contamination, water intrusion, and fuel degradation under severe duty cycles.

Applications include Excavators (325, 325L, 322L, 320 Series), Wheel Loaders (938F, 950F, 950G), Articulated Trucks (D250E, D300E), commercial marine vessels, and stationary generator sets serving North America, Europe, the Middle East, Southeast Asia, and South America. Installation follows a defined ten-step procedure: disconnect battery, clean injector bore, remove old injector, inspect seat, install sealing washer, install the 0R-8465 unit, torque to specification, reconnect fuel lines, prime the system, and perform leak testing.
