original 116-5425 Common Rail Diesel Fuel Injector Assembly for C10 C12 E345B Excavator Engine 1165425 10R1258 161-1785 203-3464 Auto Parts Injector original new injector

Engineered for demanding heavy-duty diesel service, this C12 series fuel injector under primary OE number 116-5425 delivers dependable fuel delivery performance for C12, C-12 and 3196 diesel engine applications. The injector assembly is manufactured with high-strength internal components, wear-resistant precision parts, and reliable sealing surfaces to withstand the elevated pressures and continuous duty cycles typical of on-highway trucks, construction machinery, mining equipment, marine auxiliary units, and stationary power generation systems.

Broad cross-reference coverage simplifies global procurement and inventory matching. Interchange numbers include 0R-4988, 10R-0968, 156-1011, 212-3466, EX630968, 630968, 176-1145, 176-1160, CA1165425, CA0R4988, CA10R0968, CA1561011 and CA2123466. Each injector is designed for direct replacement fitment with precision fuel metering and fine diesel atomization, helping fleet operators and engine rebuilders restore rated power output, reduce black smoke, improve fuel efficiency, minimize downtime, and rebalance cylinder performance. Injectors can be supplied individually or as a matched engine set for complete overhaul projects.

Recommended installation should be performed by qualified diesel technicians following the official engine service manual for correct torque values, sealing requirements, trim code programming, and calibration procedures. Regular maintenance includes clean diesel fuel usage, scheduled fuel filter replacement, water separator draining, leak inspection, and periodic injector flow and spray testing. This component is supplied to distributors, workshops, and OEM buyers across North America, Europe, the Middle East, Africa, Southeast Asia, Australia, and South America.
