original 232-1171 Diesel Fuel Injector for 3408 3412 Engine Excavator Common Rail Injection Nozzle Assembly Replacement for OEM 2321171 10R-1267 original new injector

Engineered for demanding heavy-duty operations, the 232-1171 fuel injector delivers precision fuel delivery for 3412, 3412C, and 3412E V12 diesel engines. Manufactured from corrosion-resistant hardened steel and featuring a precision-machined multi-hole nozzle, this injector ensures consistent fuel spray patterns and superior atomization under continuous industrial and marine service. Referenced to OE 10R-7223 with cross numbers 237-8671 and 0R-7223, it provides OEM-standard fitment for seamless engine integration in the 3412 series 18.1L platform.

Designed to withstand operating pressures of 2200–2500 bar, this direct injection unit measures 120mm in length and 30mm in diameter, weighing 0.8 kg. It is rigorously tested for vibration resistance, extreme temperature performance, and continuous duty cycles, making it suitable for 3412 excavators, bulldozers, underground and open-pit mining engines, tugboats, yachts, industrial diesel generators, pumps, and compressors. Compatibility with both high-sulfur and low-sulfur diesel fuels ensures reliable performance across global markets and fuel standards.

Installation requires torque of 45–50 Nm with SAE 37° flare fuel line connections and proper injector seat cleaning. Recommended maintenance intervals are 500–800 operating hours, with seal replacement every 1000 hours. The unit is backed by a 12-month industrial warranty, supporting B2B buyers seeking reliable replacement components for mission-critical diesel applications worldwide.
