Perkins original Perkins 156-3895 Diesel Engine Fuel Injector for Perkins 3412 3408 3412E Tractor original new injector

The Perkins 156-3895 fuel injector is a precision-engineered diesel injection nozzle assembly designed for the Perkins 3412 engine series, including the 3412, 3412B, and 3412C variants. Built as an OEM equivalent replacement, this injector delivers exact fuel metering through precision-manufactured internal components and balanced calibration, ensuring consistent cylinder-to-cylinder performance across the V12 four-stroke diesel platform. Heavy-duty hardened materials and corrosion-resistant treatment allow reliable operation under high temperatures, pressures, and harsh marine or industrial environmental conditions.

This injector assembly operates on a standard high-pressure diesel injection principle: pressurized fuel enters the injector body, the needle valve remains seated until the calibrated opening pressure is achieved, and atomized fuel is then sprayed into the combustion chamber for mixing with compressed air. This process supports complete combustion, improved fuel atomization, higher efficiency, reduced fuel consumption, lower exhaust emissions, and enhanced engine power output, contributing directly to stable engine performance in demanding applications.

Compatible with Perkins generator sets, commercial marine vessels, mining support equipment, pump drives, compressor drives, and other heavy industrial power units, the 156-3895 injector carries authorized cross references including 0R-8780, 10R-0955, and 20R-2055. Every unit undergoes strict factory flow testing and quality inspection before shipment. Suitable for Perkins dealers, engine rebuilders, fleet operators, generator manufacturers, marine service companies, mining contractors, and industrial maintenance providers worldwide, the injector is backed by global export support and full technical documentation.
