Caterpillar original 324-5467 Fuel Injector 20R-5078 304-3637 363-0493 Diesel Common Rail Injector for CAT C9.3 Excavator Truck Sprayer Wheel Tractor Cold Planer original new injector

For operators managing CAT C9.3 engine-powered industrial assets, the 324-5467 fuel injector assembly is a precision-engineered diesel injection component built to meet or exceed OEM specifications. Designed for high-pressure common rail fuel systems, it delivers precise fuel atomization to optimize combustion efficiency, enhance power output, reduce fuel consumption and emissions, and support stable engine operation even under demanding heavy-duty conditions. It is constructed from high-strength alloy steel for reliable long-term performance.

This injector is compatible with all documented C9.3 engine variants, including standard C9.3, C9.3 ACERT, C9.3B, industrial C9.3 and generator set C9.3 models. It fits common CAT equipment including 336/340 excavators, 966/972 wheel loaders, motor graders, soil compactors, generator sets, industrial power units and mining machinery, serving construction, mining, power generation, agricultural, marine and general industrial sectors. Cross-reference numbers include 326-4700 and 387-9433, and final compatibility depends on engine serial number and machine arrangement.

As a brand-new OEM-specification part in industrial protective packaging, it features corrosion resistance and a rugged heavy-duty design to extend service life and lower long-term maintenance costs. Following official CAT installation guidelines and adhering to recommended maintenance practices, such as using ultra-clean diesel and replacing filters regularly, will sustain optimal injection performance and support consistent equipment operational efficiency.
