original 295050-0421 Common Rail Fuel Injector 370-7287 T409983 20R-2480 Diesel Injector for C4.4 4-Cylinder Excavator Generator Common Rail Diesel Engine original new injector

Engineered for demanding industrial diesel platforms, the 295050-0421 common rail fuel injector delivers precise high-pressure fuel atomization for the C4.4 engine family, including C4.4 ACERT, C4.4 Tier 3, C4.4 Tier 4, and C4.4 Industrial and Generator variants. Manufactured to OEM quality standards with precision machining, this 4.4 liter inline four cylinder diesel injector ensures stable fuel delivery, optimized combustion, reduced emissions, and improved fuel economy across long service intervals.

This injector is a direct-fit replacement identified by OE number 295050-0421 and interchanges with cross references 2950500421, 295050-0420, 2950500420, 295050-0422, 2950500422, 295050-0419, and 2950500419. It is suitable for excavators, wheel loaders, backhoe loaders, skid steers, telehandlers, generator sets, industrial power units, agricultural equipment, mining equipment, and general construction machinery, supporting construction, mining, agriculture, power generation, industrial, and marine auxiliary applications with high pressure resistance, corrosion resistance, and wear resistance.

For reliable service, use ultra-clean diesel fuel, replace fuel filters regularly, and perform periodic injector balance testing. During installation, clean injector seats, use new sealing components, verify fuel pressure, calibrate if required, and check for leakage after startup. Common diagnostics include hard starting from injector wear, black smoke from poor atomization, power loss from reduced flow, fuel leakage from internal damage, rough idle from imbalance, and misfire from solenoid failure.
