Perkins original  Common Rail Diesel Fuel Injector Nozzle Assembly 194-5083 194-5080 20R-0055 For C10 C12 345B Excavator original new injector

The Perkins 194-5083 fuel injector is a genuine replacement component engineered for Perkins C12, Perkins C12 ACERT, and Perkins C13 Early Series diesel engines. Manufactured under strict dimensional tolerance control, this OEM-level injector assembly ensures precise fuel delivery and consistent atomization across demanding operating cycles in construction, mining, transportation, marine, and power generation applications.

Featuring advanced nozzle geometry, the 194-5083 injector produces ultra-fine fuel droplets that promote complete combustion and improve overall fuel economy. Premium alloy steel construction delivers superior wear resistance, while specialized surface treatment provides reliable corrosion protection against sulfur-containing fuels and harsh industrial environments. The injector is designed to support emission control compliance and long service life under heavy-duty operational conditions, making it a dependable choice for Perkins 330 Series Excavators, 966 Series Wheel Loaders, 725 Series Articulated Trucks, Perkins Gensets, and Perkins Marine Systems.

Compatible with cross reference numbers 194-5083, 1945083, 10R0957, 10R0958, 0R9350, 0R-9350, 10R-0957, and 10R-0958, this injector assembly integrates seamlessly with existing fuel systems. Recommended maintenance includes fuel filter replacement every 250-500 operating hours, injector inspection every 2,000 operating hours, fuel system cleaning every 2,000-3,000 operating hours, and injector testing every 4,000 operating hours. Diagnostic procedures such as fuel pressure testing, injector balance testing, return flow testing, electrical resistance testing, ECM diagnostic scanning, and cylinder cut-out testing help ensure sustained performance and reliability across the full service lifecycle.
