original 370-7287 Fuel Injection Valve Diesel Injector for C4.4 Engine 312E 420F Excavator 20R2480 3707287 new injector original new injector

Engineered specifically for the C4.4 Diesel Engine 4.4L platform, the 370-7287 fuel injector delivers OEM-grade precision in a high-pressure common rail system operating at 1600–2000 bar. Its multi-hole nozzle produces an optimized spray pattern that promotes complete atomization, supporting cleaner combustion across turbocharged and naturally aspirated variants. The high-strength steel alloy construction with wear- and corrosion-resistant materials ensures dependable performance in demanding environments, from excavator hydraulic systems to standby generator sets.

This injector is designed for broad compatibility with C4.4-powered equipment, including Excavators such as the 305E2, 308E2, and 309D, Loaders including the 906H and 908M, Skid Steers such as the 226D and 232D, and C4.4 Diesel Generator Sets. It also serves construction machinery like dozers, compactors, and graders, as well as agricultural tractors and harvesters. Authorized cross-references include 287-4973, 287-4972, 10R-7220, 326-4754, 326-4765, 326-4770, and 326-4771, supporting global aftermarket and OEM replacement needs across North America, Europe, Asia-Pacific, Africa, and the Middle East.

Installation follows a straightforward sequence: clean the nozzle seat, lubricate sealing surfaces, install the injector, torque to 30–35 Nm, and test the system. The M14x1.5 fuel line connection and precision timing control simplify maintenance while helping reduce fuel consumption and emissions. Operators should depressurize the fuel system before service, use authorized replacement parts, and inspect periodically for leaks, nozzle wear, or clogging to maintain long service life under heavy load conditions.
