original 370-7281 fuel injection assembly replacement for OEM new injector original new injector

Engineered exclusively for the C4.4 diesel platform, the 370-7281 fuel injector delivers precise compatibility across the C4.4, C4.4 ACERT, C4.4 Generator, C4.4 Industrial, and C4.4 Agricultural engine variants. The high-pressure common rail system operates between 1800–2200 bar, integrating seamlessly with the factory ECU to maintain accurate injection timing, fuel quantity, and cycle duration. Verified cross references 209-4394, 320-7281, and 0R-7281 allow direct replacement without modification, ensuring drop-in fitment for original mounting configurations.

Manufactured from hardened alloy steel with anti-corrosion surface treatment, this injector meets OEM equivalent tolerances through CNC precision machining. The multi-hole nozzle design achieves uniform fuel atomization at a controlled flow rate of 60–65 L/h at 200 bar, promoting optimized combustion, improved fuel economy, and reduced NOx and particulate emissions. Solenoid-based electronic actuation ensures consistent response under heavy-duty load conditions encountered in construction, mining, and power generation applications.

Built for demanding industrial environments, the 370-7281 supports a wide range of -powered equipment including 906H, 908M, 914M wheel loaders, 308E2, 309E2, 311F excavators, 416F2, 420F2 backhoe loaders, TH414, TH336 telehandlers, 236D3, 242D3 skid steer loaders, CB24B, CB22B road rollers, and C4.4 generator and tractor power units. Backed by a 12-month or 1000-hour warranty, this injector provides long service life and reliable performance for fleet operators and service workshops maintaining C4.4 machinery.
