Caterpillar original Caterpillar 194-5080 Common Rail Fuel Diesel Injector for C10 C12 345B Excavator Replacement for OEM new injector original new injector

The Caterpillar C12 Fuel Injector 194-5080 is engineered to deliver precise fuel metering and high-pressure atomization for the CAT C12 diesel engine platform. Built with high-strength alloy steel and corrosion-resistant components, this injector assembly meets OEM tolerances for flow rate, spray pattern, and injection timing. It is calibrated to restore factory-specified combustion performance across heavy-duty trucks, mining equipment, construction machinery, marine propulsion systems, and generator sets powered by the C12 EUI architecture. The injector undergoes factory testing prior to shipment to ensure consistent performance under demanding industrial duty cycles.

This injector 194-5080 is available in new, OEM equivalent, and remanufactured conditions to support flexible inventory and service strategies. It is interchangeable with part numbers 10R0957 and 0R8479, enabling straightforward cross-referencing during fleet maintenance and engine overhaul procedures. Precision-machined nozzle geometry promotes stable injection pressure, improved fuel economy, reduced exhaust smoke, and enhanced engine output across long-haul, off-highway, marine, and stationary power applications.

Proper installation requires relieving fuel system pressure, disconnecting battery supply, inspecting the injector bore, replacing O-rings and sealing washers, applying OEM torque values, bleeding the fuel system, and performing a post-installation diagnostic check. Operators should use clean diesel, replace fuel filters at recommended intervals, prevent water ingress, and monitor for fault codes to maximize injector service life.
