Caterpillar original 0R-1758 Fuel Injector for Caterpillar 3500A 3508 3512 Diesel Fuel Injector Auto Spare Parts, Replacement for OEM 7E-2269, Cross Reference 0R-0906, 0R-1756 original new injector

As a purpose-built fuel injection component for heavy-duty Caterpillar power platforms, the CAT 0R-1758 diesel fuel injector meets strict OEM specifications for fit, form and function. It is engineered exclusively for CAT 3512A engine variants across marine, generator, industrial, mining and offshore configurations, and acts as a direct OEM replacement part with verified cross-reference part numbers for seamless part matching. The injector comes with a 12-month warranty to guarantee reliable service performance.

Operating within the engine’s high-pressure diesel fuel system, the 0R-1758 injector follows a precision fuel delivery process: high-pressure fuel enters the assembly, the internal valve responds to injection signals, the needle lifts to atomize fuel through precision nozzle holes, and the unit closes immediately after delivery to support optimized air-fuel mixing. Its industrial-grade alloy construction and wear-resistant internal components deliver stable fuel metering, high-pressure delivery, corrosion resistance and a long service life, while improving combustion efficiency, reducing fuel consumption and exhaust emissions, and minimizing engine knock.

Validated for extreme operating conditions, the 0R-1758 injector is suitable for a wide range of heavy equipment across power generation, marine transportation, mining, oil and gas, and industrial manufacturing sectors. It delivers proven field reliability, stable power output and enhanced engine response, with competitive lifecycle costs and global availability to support B2B equipment maintenance and operation needs across regional markets.
