Denso 23670-UM010 Fuel Injector Assembly

The 23670-UM010 fuel injector assembly is engineered for Toyota 1ZS and 1Z series 3-cylinder diesel engines installed in Toyota 8FDU15 through 8FDU32 internal combustion counterbalance forklifts. This component delivers precise high-pressure fuel metering directly into the combustion chamber, ensuring optimal atomization, combustion efficiency, and cold-start reliability in material handling duty cycles. Manufactured to OEM specifications by Denso, this injector assembly replaces Toyota part number 23670-UM010 and cross-references Denso component 295050-1680. It features electromagnetic solenoid actuation compatible with 24-volt vehicle electrical systems standard on Toyota industrial lift trucks. The nozzle assembly is calibrated for the specific injection pressure and spray pattern required by the 1ZS/1Z engine family. Designed for direct injection diesel systems, the injector body incorporates high-strength alloy steel construction to withstand peak cylinder pressures and thermal cycling. Each unit undergoes flow balancing and seat leakage testing to meet ISO 9001 / IATF 16949 quality standards for heavy-duty off-highway applications. Installation requires new copper sealing washers and torque-to-yield hold-down bolts per Toyota service manual procedures.
