Perkins original Perkins 370-7287 Diesel Fuel Injector Common Rail for C4.4 312E 420F Excavator 20R-2480 new injector original new injector

The Perkins C4.4 fuel injector 370-7287 is engineered as a direct OEM-grade replacement component for Perkins C4.4 series diesel engines, delivering consistent atomization through its precision multi-hole nozzle and high-pressure common rail design. Operating at working pressures of 1600–2000 bar, this injector ensures accurate fuel metering and optimized combustion timing, which directly contributes to reduced fuel consumption and lower exhaust emissions across demanding duty cycles. The body is manufactured from high-strength steel alloy with wear-resistant and corrosion-resistant properties, providing extended operational life under extreme load conditions and harsh environmental exposure.

This injector offers broad compatibility across multiple Perkins-powered equipment platforms, including excavators (305E2, 308E2, 309D), C4.4 diesel generator sets, loaders (906H, 908M), skid steers (226D, 232D), dozers, compactors, graders, and agricultural tractors and harvesters. Authorized cross-reference numbers include 287-4973, 287-4972, 10R-7220, 326-4754, 326-4765, 326-4770, and 326-4771, supporting global aftermarket replacement needs across North America, Europe, Asia-Pacific, Africa, and the Middle East.

Installation follows a straightforward sequence: clean the nozzle, lubricate sealing surfaces, install using an M14x1.5 fuel line connection, torque to 30–35 Nm, and test for proper operation. Always depressurize the fuel system before service. Periodic inspection for leaks and nozzle wear, combined with the use of clean diesel fuel and recommended industrial solvents, ensures long-term reliability and sustained engine performance.
