| No. | Question | Standard Answer |
|---|---|---|
| Q1 | Which equipment match 24V fuel shutoff solenoid valve 165-4026 1654026? | This flange fuel cut-off solenoid fits CAT 3406/3408/3412 heavy diesel engines and E312C/E320B/E320C excavators injection pump fuel system, adopting four copper screw terminal design. |
| Q2 | What core working principle of this fuel stop solenoid? | Energized: electromagnetic force pulls plunger open fuel channel to supply fuel for engine startup; power off: built-in strong spring resets plunger to instantly cut fuel supply and realize safe flameout. |
| Q3 | What engine faults will be triggered by damaged solenoid? | Engine cannot shut down completely, hard cold startup, intermittent flameout during heavy load operation, diesel leakage at injection pump, abnormal high engine compartment temperature. |
| Q4 | Is full disassembly of the fuel injection pump required during replacement? | No, flange fixed mounting design, only remove two fixing bolts and replace the whole solenoid assembly, no need to split the injection pump housing. |
| Q5 | What high-temperature resistant structure adapts to harsh engine compartment environment? | H-grade high temperature enameled integral winding coil, double HNBR oil-resistant high temperature sealing rings, integrated injection molding waterproof insulated terminals, stable performance under long-term high oil temperature and vibration. |
| Q6 | Are 165-4026 and 1654026 interchangeable OEM spare part numbers? | Yes, the two codes correspond to the same complete fuel shutoff solenoid assembly and can be directly replaced mutually without modification. |
| Q7 | How to quickly test coil integrity before installation? | Use a multimeter to measure coil resistance, normal range 14–14.8 ohms; infinite resistance represents open circuit, resistance below 10 ohms indicates internal short circuit and cannot be installed. |
