Caterpillar original 0R-3580 Fuel Injector Common Rail Diesel Injectors Replacement for 3114 3116 3126 Truck Excavator Auto 162-0212 0R-8475 4P2995 original new injector

The Caterpillar 3116 fuel injector 0R-3580 is an OEM-specification replacement component designed for the CAT 3114, 3116, 3116B, and 3116C diesel engine platforms. Covering a displacement range from the 6.6-liter 4-cylinder 3114 to the 10.3-liter 6-cylinder 3116 series, this injector is engineered to deliver consistent fuel metering across industrial, construction, marine, generator, agricultural, and heavy-duty power unit applications. It cross-references with 0R3580, OR3580, CA0R3580, 127-8220, 127-8222, 107-7734, 107-7773, 9Y-4982, 4P-2995, 0R0471, 0R8467, and 0R8633, supporting direct fitment without modification.

Manufactured using CNC precision grinding technology, the injector achieves tight dimensional tolerances that stabilize injection timing and fuel quantity at every RPM range. A multi-hole nozzle configuration promotes optimized fuel atomization, producing a fine spray pattern that improves combustion efficiency, reduces smoke output, and lowers overall fuel consumption. The internal plunger and nozzle components are produced from hardened alloy steel, providing superior wear resistance under continuous high-pressure operation in demanding work cycles.

Built to operate reliably under sustained heavy load conditions, the 0R-3580 injector incorporates advanced surface treatment technology that delivers corrosion protection against moisture, fuel impurities, and harsh operating environments. It meets or exceeds OEM performance specifications for the Caterpillar fuel injection system, ensuring balanced cylinder pressure, stable idle quality, and extended service intervals. As a direct OEM reman exchange unit, it provides a dependable, cost-effective service solution for fleet maintenance operators and engine rebuild professionals maintaining CAT 3116-series powered equipment.
