A fuel shut-off solenoid (also called fuel cut-off valve, stop solenoid, flame-out device, or stop switch) is a key actuator in the diesel engine fuel supply system, mounted on the injection pump or high-pressure fuel line and controlled by the cab key switch or stop button . Its working principle: the solenoid contains a coil; when energized it generates magnetic force pulling the plunger (or stop lever) back to the fuel-on position for normal engine operation; when de-energized the magnetic force disappears and a spring pushes the plunger back to the stop position, cutting off fuel supply and halting the engine . This "energize-to-run, de-energize-to-stop" logic ensures the engine can be reliably shut down under any operating condition, serving as an important safeguard for diesel engine safety.
The number 13026697 is mentioned by multiple suppliers across the supply chain:
Shandong Dongshang Machinery labels it as a "Weichai-Deutz 226B engine 24V loader fuel cut-off solenoid" and a "Weichai 50-class loader engine stop solenoid" ;
Another listing labels it a "Deutz engine fuel shut-off solenoid" alongside Cummins series universal types ;
Qipeiren.com supplies it as a 24V flame-out device for "imported construction equipment excavator aftermarket spares", branded TG .
Taken together, 13026697 is a generic number for Weichai-Deutz-series diesel engine fuel cut-off solenoids, which may correspond to similar fuel cut-off actuators across different engine brands in different supply channels. Note that even with the same number, different brands and engine models may adopt different coil resistance, plunger stroke, mounting threads, and port forms—hence matching must still be confirmed against a physical sample or original catalog.
This 860123608 is user-labeled 24V, consistent with the voltage parameter of 13026697 shown on supplier pages, but the correspondence between 860123608 and 13026697, and between this part and specific models, cannot be confirmed from public sources and requires verification through XCMG's parts system or catalog numbering. XCMG's official spare-parts service notes that construction machinery encompasses a vast range of components, and entering the part number, model, or keyword enables quick lookup of the required genuine spare parts.
The fuel shut-off solenoid is a high-frequency actuation component in diesel engines. Common failure modes include: coil burnout preventing energization, plunger sticking (dust or mud obstructing piston movement) causing failure to supply or cut fuel, spring fatigue causing slow return, and seal aging causing fuel leakage . When symptoms appear—engine won't start (plunger not pulled in), engine won't stop after key-off (plunger stuck in fuel-on position), or random mid-operation stalling (coil open-circuit or poor contact)—timely inspection and replacement are necessary. When replacing, work only after the engine has completely cooled: first disconnect the battery negative terminal, detach the fuel line and electrical connector, then remove the mounting bolts to take off the old unit; when installing the new unit ensure the O-ring and gasket are intact, screw in squarely without misalignment, tighten to the specified torque, then reconnect the harness and fuel line, bleed the air, and verify the fuel on/off action after startup.
