Perkins original Perkins original Perkins 105-1694 Diesel Engine Fuel Injector for Perkins 3116 Excavator 320B 325B Construction Machinery Replacement for OEM new injector original new injector

The Perkins 3116 Fuel Injector 105-1694 is an original equipment mechanical unit injector engineered for the Perkins 3116 diesel engine platform, covering naturally aspirated, turbocharged, industrial, marine, and generator configurations including 3116TA and 3116DITA variants. Built from heat-treated alloy steel, this injector is designed for continuous duty in high-pressure mechanical diesel fuel systems found across construction machinery, generator sets, marine engines, agricultural equipment, and oilfield power units.

Precision-machined to micron-level tolerances, the 105-1694 injector delivers consistent fuel delivery and optimized nozzle geometry for superior atomization. Protective surface treatment resists corrosion from fuel contamination and moisture, ensuring long service life that exceeds OEM durability standards. It is compatible with cross references 127-8218, 0R-8684, 317-4375, 0R-5191, 4P-2995, and 7E-8727, providing a reliable replacement solution for fleet maintenance and engine remanufacturing programs.

This injector improves combustion efficiency, lowers fuel consumption, reduces exhaust emissions, and increases engine power output across demanding applications such as excavators, wheel loaders, motor graders, fishing vessels, prime power stations, tractors, harvesters, and mining trucks. Recommended maintenance includes using clean diesel fuel, regular fuel filter replacement, periodic inspection of fuel lines, and injector testing during major engine service intervals to sustain peak performance.
