Engineered specifically for the 3116 diesel platform, this OR-4374 fuel injector assembly delivers precise fuel metering and consistent atomization across 3116, 3116T, 3116TA, and marine and generator variants of the 3116 series. Each unit is manufactured to OEM fuel system specifications, ensuring dimensional accuracy and direct-fit compatibility with the 3116 cylinder head injector bore. The component is validated for use in construction, mining, marine, power generation, agriculture, and oil and gas equipment powered by the 3116 engine family.

The injector incorporates advanced atomization technology that supports stable combustion pressure, optimized power output, and reduced exhaust emissions throughout the operating range of the 3116. Industrial-grade materials and precision-machined internal components deliver long-term reliability under heavy-duty cyclic loads and extended service intervals. Authorized cross references including 0R4374, OR4374, CA0R4374, 101-8673, 127-8213, 7E-6193, 105-1694, 140-8413, 0R8473, and 0R8867 provide comprehensive coverage for replacement requirements on the 3116 engine platform.

Before installation, inspect fuel lines, fuel pump condition, injector seat, and the cylinder head injector bore, and replace any damaged seals. Clean the mounting surface, install new sealing washers, position the injector correctly, and tighten to OEM torque specifications before connecting fuel lines and bleeding the system. ISO-compliant diesel with low contamination and appropriate cetane rating is required to prevent nozzle wear, carbon deposits, and reduced atomization on 3116 engines.
