original 232-1175 Diesel Fuel Injector for 3412E 3408E Engine 769D 771D 775D Truck Replacement for OEM 2321175 10R-1267 20R-5392 10R-9238 Injector Nozzle original new injector

Engineered for heavy-duty diesel performance, the 232-1175 Fuel Injector is a precision-manufactured component designed for the 3412, 3412B, and 3412C V12 diesel engine series. Serving as a direct OEM replacement, this injector cross-references part numbers 10R-7222, 10R-7223, and 2321175, ensuring seamless compatibility with industrial generators, marine propulsion units, mining equipment, and construction machinery operating between 500–750 HP and 650–850 HP output ranges.

Built from hardened steel to withstand extreme high-pressure injection cycles, the 232-1175 delivers optimized atomization through a precision nozzle geometry that reduces emissions and enhances fuel efficiency. Its corrosion-resistant construction is well-suited for marine, oil & gas, and agricultural environments, while OEM-compliant specifications guarantee reliable performance and long service life exceeding 1000+ operating hours. Installation is straightforward, requiring a torque of 35–45 Nm with proper alignment and clean cylinder head ports for optimal seating.

Maintenance is streamlined with recommended inspection intervals every 500 operating hours; ultrasonic cleaning is advised for deposit removal, and approved diesel fuel should be used to prevent nozzle clogging. Common diagnostic scenarios—hard starting, smoke emission, fuel leaks, and power loss—can be resolved by cleaning or replacing the injector, replacing worn nozzles or O-rings, and verifying injector timing and pressure. This injector is an essential component for B2B buyers seeking dependable, high-performance fuel system parts for the 3412 series.
