original 10R-0959 Diesel Fuel Injector for C15 3406E 3456 Engine Truck Genset Replacement OEM 10R0955 10R-0956 253-0614 200-1117 229-5919 20R-2284 Parts original new injector

Engineered for heavy-duty diesel platforms, the 10R-0959 fuel injector delivers precision-metered high-pressure injection for C15, C15 ACERT, C15 Industrial, C15 Marine, C16, C16 Industrial, 3406E, and 3406E Marine engines equipped with the Electronic Unit Injector (EUI) fuel system. This OEM remanufactured unit is a direct replacement referenced by 249-0713, 253-0616, 328-2577, 387-9433, and 20R-2053, giving fleet operators, remanufacturers, and MRO buyers a fully cross-verified sourcing option.

Each injector features hardened wear-resistant components, corrosion-resistant construction, and electronic solenoid-controlled operation for consistent atomization and cylinder balance. Every unit is subjected to 100% flow and leakage testing against OEM calibration curves, delivering improved fuel economy, enhanced power output, lower particulate emissions, reduced engine noise, and faster throttle response. Typical applications include Peterbilt, Kenworth, and Freightliner long-haul trucks, mining haul trucks, excavators, wheel loaders, diesel generator sets, marine vessels, and oilfield pumping and drilling power units.

For maximum service life, use ultra-clean diesel fuel, replace fuel filters on schedule, monitor injector balance rates, and routinely check ECM fault codes such as Injector Circuit Fault, Cylinder Contribution Fault, Fuel Delivery Fault, High Return Flow Fault, and Solenoid Resistance Fault. During installation, thoroughly clean the injector bore, replace O-rings and seals, lubricate sealing surfaces, perform ECM calibration, and complete a post-installation leak inspection to ensure reliable operation.
