Caterpillar original Diesel Fuel Injector 342-5487 324-5467 364-8024 20R-5077 Common Rail Replacement for C9.3 Engine, Sprayer Excavator Truck Loader Bulldozer Construction original new injector

For procurement teams, heavy equipment fleet operators and maintenance service providers sourcing reliable fuel system replacement parts for Caterpillar C9.3 engine platforms, the CAT 342-5487 diesel fuel injector is a precision-engineered original new assembly built to strict OEM specifications. Designed as a direct-fit component for C9.3 series engines including base C9.3, C9.3 ACERT, industrial and generator set variants, it matches factory configuration requirements to avoid the fitment and performance risks posed by low-quality aftermarket alternatives.

Engineered for high-pressure common rail diesel fuel systems, the injector features a multi-hole atomization nozzle and ECM-regulated precision injection timing. During operation, the Electronic Control Module activates the injector solenoid to feed pressurized fuel into the nozzle chamber, atomizing fuel into fine particles for full, controlled in-cylinder combustion. This structure boosts combustion efficiency, reduces fuel consumption and exhaust emissions, improves throttle response and power output, and its corrosion-resistant industrial-grade construction delivers stable durability under high-temperature heavy-load conditions.

Suitable for construction, mining, industrial, marine auxiliary and power generation scenarios, it fits Caterpillar excavators, wheel loaders, motor graders, generator sets, industrial power units and mining equipment. The part comes with a 12-month warranty and industrial export packaging, and fitment must be verified via engine serial number, arrangement number and equipment serial number before purchase. Installers should clean the fuel system and replace filters pre-installation, while regular injector balance monitoring supports long-term stable operation.
