Caterpillar original Engine Injector 169-7408 for Caterpillar C9.3, Cross Reference 460-8213, 20R-5075, Replacement for OEM, Excavator E336E Parts with 456-3509 original new injector

The Caterpillar 169-7408 is an original new high-pressure electronically controlled diesel fuel injector purpose-built for the CAT C9.3 engine platform. Manufactured strictly in line with Caterpillar OEM specifications, it delivers precise fuel metering and superior atomization to maintain consistent engine power output, improve fuel economy, support emissions compliance, and guarantee reliable long-term operation. It is widely referenced across Caterpillar’s OEM supersession, dealer replacement, remanufactured program, and global diesel fuel injection catalogs.

Operating within a high-pressure common rail fuel system, the injector supports working pressures ranging from 1,800 to 2,200 bar. When the ECM sends an electrical signal, the injector solenoid activates to lift the needle valve, forcing fuel through precision nozzle holes to create ultra-fine droplets for full combustion, which cuts black smoke, PM and NOx emissions, and reduces excess fuel consumption. Its industrial-grade construction offers extended service life and corrosion resistance for harsh mining, quarry, construction, agricultural, marine, humid, coastal, and high-temperature operating conditions.

This injector is compatible with a full range of CAT heavy equipment, including 336/340/349-series excavators, 950M–972M wheel loaders, 140M–160M motor graders, CS/CP-series compactors, DE-series generator sets, and mining support equipment. It serves as a dependable OEM replacement solution for heavy-duty operations across construction, mining, power generation, industrial, agricultural, and marine sectors worldwide.
