original 0R-0471 Diesel Engine Fuel Injector for 3116 Excavator 200B 320B 322B 325B 446B Mechanical Fuel Injector Nozzle 0R0471 9Y-4982 102-7038 127-8205 original new injector

Engineered for demanding industrial and mobile diesel applications, this 3116 mechanical fuel injector assembly (OE 0R-0471) delivers reliable, precision-metered fuel injection for the 3116 inline six-cylinder, 4-stroke diesel platform. With approximately 6.6 liters of displacement and power ratings from 205 to 350 HP, the 3116 platform requires injectors that maintain tight tolerances under continuous heavy loads. This unit is manufactured to meet OEM specifications and is available in both original and aftermarket configurations, including remanufactured options for cost-effective fleet sourcing.

Key engineering features include precision-machined internals for accurate fuel delivery, hardened nozzle tips for optimized atomization, and thermal- and wear-resistant materials for extended service life. The robust mechanical design ensures dependable operation in excavators (200B, 205B, 320B, 322B, 325B), the 446B backhoe/loader, medium-duty trucks, marine engines, generator sets, and industrial pumps and compressors. Broad cross-reference compatibility—covering 4P-9077, 9Y-4982, 101-4561, 127-8205, 0R-3389, 0R-8467, 0R-8682, 127-8220, 4P-2995, 7E-8952, 105-1694, 7E-8727, 162-0212, and 127-8230—simplifies procurement for distributors and MRO buyers.

Recommended maintenance includes clean diesel fuel, scheduled filter replacement, water separator draining, and bench testing for pop pressure and spray pattern. Correct installation and upkeep help prevent hard starting, rough idle, black smoke, low power, and seal-related fuel leaks, ensuring optimal combustion efficiency and long-term operational reliability.
