Engineered for demanding heavy-duty service, this 3116 series diesel fuel injector delivers a direct-fit replacement solution for operators managing construction, marine, generator, and industrial power fleets. Identified by primary OE number 0R-8471 and fully cross-referenced with 4P-2995, 7E-8952, 0R-3389, 0R-3006, and CA-prefixed equivalents, the assembly is manufactured to industrial-grade standards and supplied as a single unit or matched 6-piece set for full-engine overhauls.

Core functions include precise fuel metering, high-efficiency atomization, combustion stability, and reliable pressure and timing control. Every injector undergoes leak testing and flow testing to ensure consistent spray pattern, sealed operation, and balanced cylinder performance across the 3116 diesel engine platform. Typical applications cover excavators, wheel loaders, heavy trucks, marine propulsion units, generator sets, mining support equipment, and agricultural machinery deployed across North America, South America, Europe, the Middle East, Africa, Southeast Asia, and Australia.

Before installation, verify the old injector number, engine model, engine serial number, and machine application, then clean the fuel system, renew all seals, and follow official torque and adjustment procedures. This injector resolves common symptoms such as hard starting, rough idle, black or white smoke, misfire, power loss, and high fuel consumption. Ideal for diesel repair shops, remanufacturing workshops, parts wholesalers, and heavy equipment fleet operators seeking dependable long-service replacement components.
