original 194-5083 Common Rail Diesel Fuel Injector Nozzle Assembly for C10 C12 Engine 345B Excavator Replacement for OEM 1945083 10R-0963 20R-0055 original new injector

Engineered for demanding heavy-duty operations, the 194-5083 Electronic Unit Fuel Injector delivers OEM-equivalent performance for C12 series diesel engines. This injector assembly is precision-manufactured to strict dimensional tolerances, ensuring seamless drop-in compatibility with C12, C12 ACERT, C13 Early Series, Industrial C12, Marine C12, and Generator C12 power plants. Cross-referenced with 10R0957, 10R0958, and 0R9350, it serves as a reliable replacement across a broad spectrum of industrial fleets.

Built from premium alloy steel with a hardened steel nozzle and anti-corrosion surface treatment, this injector provides superior wear resistance against sulfur-containing fuels and harsh operating environments. Advanced nozzle geometry generates ultra-fine fuel atomization for complete combustion, optimizing fuel economy and supporting emission control compliance. Electronic control ensures precise injection timing and metering, contributing to consistent engine output, reduced operational costs, and extended service life under continuous heavy-load duty cycles typical of construction, mining, marine, and power generation applications.

This 194-5083 injector fits 330 Series excavators, 966 Series wheel loaders, 725 Series articulated trucks, mining platforms, marine propulsion systems, diesel gensets, and oilfield power units. Recommended maintenance includes fuel filter replacement every 250-500 operating hours, injector inspection every 2,000 hours, and full injector testing every 4,000 hours. Proper installation requires verified part compatibility, clean fuel lines, correct torque specifications, new sealing washers, and post-installation fault code clearing for optimal performance.
