original 0R-8465 Diesel Fuel Injector Nozzle for 3116 3406B Engine 200B 322B 446B Industrial Excavator Replacement for OEM new injector original new injector

The fuel injector 0R-8465 is engineered as a direct-fit replacement component specifically calibrated for the 3116 and 3116B series diesel engines. Manufactured to OEM specifications with micron-level machining tolerances, this injector delivers precise fuel metering, controlled injection timing, and consistent atomization across demanding operating cycles. Its specialized metallurgy provides reliable resistance against sulfur contamination, water ingress, and fuel degradation commonly encountered in heavy-duty service environments. The unit maintains stable performance under elevated thermal loads, making it suitable for continuous operation across mining sites, marine installations, construction projects, and high ambient temperature zones.

Compatibility extends across a broad range of equipment powered by the 3116 platform, including excavators such as the 325, 325L, 322L, and 320 Series, wheel loaders including the 938F, 950F, and 950G, and articulated trucks such as the D250E and D300E. The injector also serves marine propulsion systems, commercial vessels, fishing boats, patrol craft, and marine generator sets, as well as stationary generator packages, industrial power units, emergency power systems, and prime power installations deployed in agricultural, mining, and construction sectors worldwide.

Cross-referenced against authorized numbers 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, the 0R-8465 injector supports straightforward installation following standard procedures: disconnecting the battery, cleaning the injector bore, removing the existing unit, inspecting the seat, installing a new sealing washer, fitting the replacement injector, torquing to specification, reconnecting fuel lines, priming the fuel system, and performing a leak test to confirm integrity before returning the engine to service.
