original 292-3780 Common Rail Injector 2645A718 2645A734 10R-7672 for 320D C6.4 new injector original new injector

Engineered exclusively for the C6 and C6.4 diesel platforms, this OE-specification fuel injector carries the primary part number 292-3780 and is fully interchangeable with cross references 10R-7228, 10R7228, 10R7228R, and CAT2923780. Designed for inline six-cylinder configurations with a 6.4-liter displacement, the injector integrates seamlessly with the high-pressure common rail direct injection system, ensuring precise fuel metering and consistent atomization across all operating conditions of the C6 engine family.

Manufactured from hardened alloy steel and treated with an anti-corrosion coating, this component is built to endure the demanding environments encountered in construction, mining, power generation, agriculture, and marine applications. It is a direct-fit replacement for 320D, 320DL, 321D, and 323D excavators, 924H, 930H, and 938H wheel loaders, C6 generator sets, and industrial power units. The injector delivers stable idle performance, improved cold start capability, lower exhaust emissions, reduced engine noise, and extended service life, helping operators minimize maintenance downtime and maximize equipment productivity in the field.

To preserve injector reliability and protect the high-pressure fuel system, regular maintenance is essential. Daily checks should focus on fuel leakage, abnormal engine noise, and exhaust smoke. Weekly inspections must include the fuel filter, fuel line integrity, and fuel pressure readings. Monthly diagnostic procedures such as injector performance testing, ECM scanning, and fuel consumption analysis are recommended. Common failure causes such as contaminated fuel, water ingress in diesel, clogged fuel filters, excessive operating hours, and high sulfur content fuel should be actively prevented to ensure long-term performance of the C6 fuel injection system.
