Caterpillar original Common Rail Fuel Injector 382-0480 for C6.6 C4.4 C3.4 Excavator Truck Spare Parts Replacement 10R-7672 2645A734 320-0680 original new injector

The CAT C6 C6.6 Common Rail Fuel Injector 382-0480 is an OEM-type replacement assembly engineered for Caterpillar C6, C6.6, and C6 Series diesel engines. Manufactured with precision machining and durable injector body construction, it delivers high-pressure fuel delivery, accurate atomization, and stable injection response under demanding industrial working conditions. The injector is designed to provide improved combustion efficiency, reduced fuel waste, and reliable engine performance across excavators, loaders, trucks, generator sets, industrial power packs, mining machinery, agricultural diesel equipment, construction machinery, and stationary power systems.

Compatible with cross reference numbers 282-0490, 292-3780, 306-9380, 306-9390, 320-0680, 2645A709, 2645A734, 2645A751, 295-9130, 10R-7938, CA3820480, and CAT3820480, this injector offers OEM-type installation compatibility with verified fitment by engine serial number, injector coding, equipment model, and original injector number. Each unit is tested for spray pattern, high-pressure resistance, and leakage resistance, then packed in export-safe packaging for international B2B distribution. Quality control ensures consistent injection quantity and dependable performance across emission levels, production years, and fuel system versions.

Proper installation and maintenance are critical for long service life. Operators should use high-quality diesel fuel, replace fuel filters on schedule, prevent water contamination, clean contaminated tanks, test common rail pressure, and avoid mixing heavily worn injectors with new units. Before installation, clean the injector bore, inspect the injector seat, replace seals, service the fuel filter, clean fuel lines, and follow Caterpillar service torque specifications. After installation, inspect for leakage, abnormal noise, rough idle, excessive smoke, and engine fault codes. Common failure symptoms such as hard starting, black or white smoke, engine misfire, high fuel consumption, loss of power, diesel knocking, or ECU fault codes may indicate worn nozzles, internal leakage, or contaminated fuel requiring immediate service attention.
