original Diesel Fuel Injector 169-7408 1697408 460-8213 20R-5075 456-3509 for C9.3 Engine E336E Excavator Common Rail Injector Assembly original new injector

Engineered as a direct OEM-grade replacement for the C9.3 engine platform, the 169-7408 common rail fuel injector delivers precision-controlled diesel injection performance for heavy-duty industrial applications. This ECM-controlled solenoid injector features a high-precision needle valve and atomization nozzle designed to operate reliably within common rail pressures of approximately 1,800–2,200 bar, supporting modern high-pressure fuel systems that exceed 2000 bar. Cross-referenced part numbers include 1697408, 138-8756, 155-1819, 171-9704, 173-9272, 173-9379, 222-5967, 222-5966, 232-1175, 232-1183, 324-5467, 364-8024, 392-9046, 456-3493, 456-3509, 456-3544, 456-3545, 456-3589, 20R-4148, 20R-5077, and 10R-1267.

Key performance benefits include precision fuel metering that ensures exact fuel quantity delivery under all load conditions, superior atomization producing ultra-fine droplets for improved combustion efficiency, and high-pressure capability engineered for continuous operation. The injector offers long service life in mining, quarry, construction, agriculture, and marine environments, plus corrosion resistance suitable for humid environments, coastal regions, and high-temperature operations. Typical fitments include 336, 336D, 336E, 336F, 340D, 340F, 349E, 349F excavators; 950M, 962M, 966M, 972M wheel loaders; 140M, 150M, 160M motor graders; CS64B, CS74B, CP74B compactors; and DE Series generator sets.

Before installation, clean the injector bore, inspect sealing surfaces, and replace the copper washer and O-rings. Never reuse damaged seals, always use calibrated torque tools, perform fuel system bleeding, and conduct injector coding when the ECM requires it.
