original 295050-0421 Common Rail Injector 370-7287 T409983 for C4.4 4-Cylinder Diesel Engine Excavator Generator 6 Months Warranty new injector original new injector

Engineered exclusively for the C4.4 platform, fuel injector 295050-0421 delivers a precise factory-matched fit for 4.4-litre inline four-cylinder diesel engines, including the C4.4, C4.4 ACERT, C4.4 Tier 3, C4.4 Tier 4, and the dedicated C4.4 industrial and generator drive variants. The electronic common rail design is calibrated to the original injection timing and pressure maps of each engine configuration, ensuring stable fuel delivery, optimized combustion, and consistent cold-start behaviour across every C4.4 application.

This direct replacement unit is built to OEM specification using high-strength alloy steel components, with precision-machined injector nozzles and high-pressure-resistant internal parts that withstand the demanding duty cycles of excavators, wheel loaders, backhoe loaders, skid steers, telehandlers, generator sets, agricultural machines, mining equipment, pumps, compressors, and marine auxiliary systems. Wear-resistant and corrosion-protected surfaces extend service life, while refined atomization supports reduced emissions and improved fuel economy in line with C4.4 performance targets. Alternative part numbers 295050-0420, 295050-0422, and 295050-0419 are fully interchangeable within the same C4.4 family.

For correct commissioning on C4.4 engines, always clean the injector seats, fit new sealing components, verify fuel rail pressure after installation, and recalibrate or balance the injectors where required. Check for leakage at startup, run the engine on ultra-clean diesel, and replace fuel filters at the recommended intervals to protect the common rail system. Periodic injector balance testing and monitoring of fuel consumption will help detect early signs of wear and keep every C4.4-powered machine operating reliably.
