Perkins original Perkins 0R-8461 Diesel Engine Fuel Injector for 3114 3116 3126 Excavator 320B 322B 325B 127-8222 20R-2051 new injector original new injector

The Perkins 3116 fuel injector 0R-8461 serves as the final precision metering device within the diesel fuel system, delivering optimized fuel atomization, stable injection characteristics, and consistent high-pressure fuel delivery. Built with a precision nozzle design and corrosion-resistant materials, this OEM-grade component supports reliable combustion efficiency, balanced power output, improved fuel economy, and controlled emissions performance across demanding operating conditions. It functions as a direct replacement assembly engineered to meet original equipment manufacturing tolerances for long service life and industrial-grade durability in heavy-duty diesel applications.

This injector is fully compatible with Perkins 3116, 3116TA, and related industrial, marine, generator, and power unit engines. Authorized cross references include 127-8222, 107-1230, 4P-1731, 0R-3580, 20R-2051, 7E-7607, CA0R8461, CA20R2051, CA7E7607, CA4P1731, OR8461, and 3116TA, allowing flexible interchange across multiple equipment platforms. It is suitable for hydraulic excavators, wheel loaders, backhoe loaders, mining machinery, road construction equipment, marine vessels, commercial boats, tug boats, prime power generator sets, and emergency backup power systems used in construction, mining, marine, power generation, agricultural, and oil and gas operations.

Proper installation and routine maintenance help maximize injector performance and service longevity. Operators should follow OEM installation procedures, replace damaged fuel hoses, clean the injector bore thoroughly, verify injection timing, inspect fuel contamination levels, and test the engine after installation. The use of premium-quality diesel fuel, regularly replaced fuel filters, clean fuel storage systems, and avoidance of water contamination further protect the fuel system. Monitoring engine performance trends and addressing warning signs such as hard starting, poor fuel economy, engine vibration, power reduction, black or white exhaust smoke, or rough engine operation helps identify fuel delivery issues before they escalate into major component failures.
