Caterpillar original Common Rail Diesel Fuel Injector 571-0940 Replacement for OEM 370-7282, Cross Reference 20R-4560, 295700-1200 for Caterpillar C4.4 C6.6 C7.1 Engine original new injector

Reliable fuel delivery is the foundation of diesel engine performance, and the Caterpillar 571-0940 fuel injector is engineered to provide it. Designed for Caterpillar C4.4 engine platforms and related industrial diesel engine families, this precision component sits at the heart of the high-pressure fuel injection system, controlling fuel quantity, spray pattern, injection timing, and atomization efficiency. Manufactured to strict OE-level dimensional standards, it delivers accurate fuel metering and optimized atomization for stable combustion under demanding operating conditions.

This injector is compatible with Caterpillar C4.4, 3044, 3044C, 3054, and 3054C inline four-cylinder diesel engines, replacing OE number 571-0940 (5710940), with replacement reference 10R-7220 and cross references 326-4706 and 326-4707. It is widely applied in Caterpillar construction machinery—including excavators, wheel loaders, backhoe loaders, skid steer loaders, compact track loaders, and telehandlers—as well as agricultural equipment, generator sets, mining equipment, and industrial power units worldwide.

Built for heavy-duty service, the injector features a high-strength alloy steel body produced through CNC precision machining to ensure dimensional consistency and fuel delivery accuracy. Hardened nozzle and internal valve assemblies provide excellent wear resistance, while advanced surface treatment protects against moisture, sulfur compounds, and fuel contaminants. Engineered for thermal stability and resistance to vibration-related fatigue, the injector also improves combustion efficiency through precise spray pattern control, reducing fuel consumption and emissions. Supplied brand-new to OEM quality standards, it is available worldwide.
