The Caterpillar 3116 fuel injector with OE number 0R-3580 is a precision-engineered diesel fuel injection component designed specifically for CAT 3114, 3116, 3116B, and 3116C engines. It is fully compatible with cross reference numbers 0R3580, OR3580, CA0R3580, 127-8220, 127-8222, 107-7734, 107-7773, 9Y-4982, 4P-2995, 0R0471, 0R8467, and 0R8633, allowing for direct substitution in a wide range of Caterpillar-powered equipment.

This injector is manufactured using CNC precision grinding technology, ensuring tight tolerances and consistent metering performance across every unit. The multi-hole nozzle configuration delivers optimized fuel atomization, which directly improves combustion efficiency, reduces fuel consumption, and lowers exhaust emissions. Built with hardened alloy steel internal components, the injector offers superior wear resistance and dependable high-pressure operation under heavy-load industrial conditions. A specialized surface treatment provides effective corrosion protection against fuel contamination and moisture, extending the service life of the assembly even in harsh operating environments such as marine, mining, and construction sites.

Meeting or exceeding OEM performance specifications, the 0R-3580 fuel injector serves as a reliable replacement solution for construction machinery, industrial equipment, marine engines, mining vehicles, generator sets, and agricultural machinery. It is suitable for excavators, loaders, bulldozers, and other heavy-duty applications powered by the CAT 3114 or 3116 series engines. With proven durability and consistent injection performance, this component helps reduce downtime, support scheduled maintenance cycles, and maintain the long-term operational efficiency of Caterpillar equipment fleets.
