Perkins original Perkins 232-1171 Diesel Common Rail Fuel Injector for 3408 3412 Engine Excavator Spare Part new injector original new injector

The Perkins 3412 Series Fuel Injector 232-1171 is engineered to deliver precise fuel atomization for the Perkins 3412, 3412C, and 3412E V12 diesel engines. Featuring a multi-hole precision spray nozzle and an operating pressure range of 2200–2500 bar, this injector ensures optimal combustion efficiency across demanding industrial environments. Its hardened steel, corrosion-resistant construction provides long-term durability under harsh operating conditions, while the OEM-standard fitment guarantees direct replacement without modification.

Designed for heavy-duty applications including construction equipment, mining machinery, marine vessels, and diesel generators, the 232-1171 fuel injector maintains consistent fuel delivery and stable spray patterns under continuous operation. The SAE 37° flare fuel line connection and compact dimensions of 120mm in length and 30mm in diameter, with a total weight of 0.8 kg, allow for straightforward installation. Recommended torque specifications of 45–50 Nm ensure secure mounting, while compatibility with high-sulfur and low-sulfur diesel fuels broadens its operational range across global industrial and marine settings.

Routine maintenance supports extended service life, with inspection intervals recommended every 500–800 operating hours. Nozzle clogging checks, seal replacement every 1000 operating hours, and the use of OEM-approved cleaning solutions help maintain injection accuracy. The 232-1171 injector is rigorously tested for vibration resistance, temperature extremes, and continuous-duty performance, making it a reliable choice for maintaining the efficiency, power output, and emissions compliance of Perkins 3412 engine-powered equipment in construction, mining, marine, and power generation sectors.
