original OR-8473 Diesel Common Rail Fuel Injector for 3114 3116 E320B E325B E322B Engine Excavator Nozzle Replacement for OEM 127-8216 127-8213 original new injector

Engineered for heavy-duty performance, the OR-8473 diesel fuel injector delivers OEM-grade injection precision for 3114, 3116, and 3126 series diesel engines. This assembly is manufactured to strict OEM specifications and cross-referenced with 127-8213, 101-8673, 4P-1734, CA1278213, CA0R8473, 459-8473, 387-9434, and 148-012-0057, providing fleet operators and equipment rebuilders with a dependable replacement solution for excavators, wheel loaders, generator sets, marine propulsion units, and industrial power packs.

The injector delivers precise fuel atomization through calibrated nozzle holes, promoting stable combustion efficiency, improved fuel economy, faster engine response, and lower emissions. As fuel enters the injector body, injection pressure builds until the needle valve opens, releasing a fine fuel mist into the combustion chamber. This controlled spray pattern reduces carbon deposits, stabilizes idle performance, and maintains reliable power output under sustained heavy-load operating conditions typical of mining, construction, and prime power generation applications.

For optimal service life, thoroughly clean the injector bore, inspect the cylinder head seating surface, and replace both upper and lower O-rings before installation. Lubricate seals, install the injector per the service manual, apply recommended torque values, bleed the fuel system, and verify operation at startup. Compatible cross numbers include OR-4374, 0R-4374, OR-3382, and 0R-3382, making this injector a versatile B2B choice for global aftermarket, remanufacturing, and OEM replacement programs supporting industrial diesel fleets.
