original Diesel Fuel Injector 4P-2995 4P2995 0R-8475 0R8473 6I3669 For Engine 3114 3116 320B 325B 322B Construction Machinery Replacement for OEM new original new injector

Engineered specifically for the 3116 diesel platform, this fuel injector delivers direct-fit compatibility with the original mounting geometry, fuel inlet, and return circuit, allowing technicians to perform a straightforward replacement without additional modification. The injector is built with industrial-grade internal components and precision-machined nozzles that restore consistent fuel atomization across all operating loads, supporting stable cold starts, smooth idle quality, and balanced cylinder output for 3116 engines installed in excavators, wheel loaders, heavy trucks, marine vessels, and generator sets.
Every unit is leak-tested and flow-tested before shipment to verify sealing integrity, spray pattern, and delivery rate, which helps reduce common 3116 complaints such as hard starting, rough idle, black smoke, power loss, misfire, and excessive fuel consumption. The injector cross-references multiple OE references, providing B2B buyers, parts wholesalers, and remanufacturing workshops with a single sourcing solution for maintenance programs and full engine overhauls. Available as a single unit or a matched 6-piece set, this injector is a practical choice for fleet operators seeking reliable 3116 service parts.
For maximum service life, use clean diesel fuel, replace fuel filters on schedule, drain the water separator regularly, and inspect injector sealing components during major engine service. When the engine has accumulated high operating hours, replacing injectors as a full matched set is recommended to maintain even fuel output and consistent atomization. If symptoms such as rough idle, elevated exhaust temperature, or fuel dilution in engine oil persist after basic checks, fuel pressure testing, injector flow testing, leak testing, and cylinder balance testing are advised to confirm injector condition before final installation.
