| No. | Question | Standard Answer |
|---|---|---|
| Q1 | Which motor graders match 24V hydraulic solenoid valve 174-3705 1743705 with green wire grey plug? | This fixed-mount auxiliary flow proportional solenoid fits 140H,120H,135H,160H heavy motor grader multi-way valve hydraulic control system, easily identified by exclusive green wire and grey rectangular waterproof plug. |
| Q2 | What core hydraulic function does this solenoid assembly realize? | It proportionally adjusts auxiliary hydraulic flow, steplessly controls leveling and ripper combined movement speed to achieve smooth earthwork operation without hydraulic jitter. |
| Q3 | What abnormal hydraulic faults will be caused by solenoid failure? | Slow leveling/ripper action, unstable hydraulic pump pressure, obvious jitter during composite operation, intermittent machine action failure and continuous abnormal high hydraulic oil temperature. |
| Q4 | Is full disassembly of the multi-way valve block required during replacement? | No, flange fixed mounting design, only remove the fixing bolts and pull out the old valve, no need to split the internal main valve housing. |
| Q5 | What special wire and plug design advantages? | Adopts dedicated green wire and grey fully sealed two-pin waterproof plug, integrated injection molding process, good dustproof and waterproof performance, adapt to muddy and dusty open-air construction environment. |
| Q6 | Are 174-3705 and 1743705 interchangeable spare part numbers? | Yes, the two codes correspond to the same complete hydraulic solenoid assembly and can be replaced mutually. |
| Q7 | Can this 24V solenoid be replaced with a 12V coil version? | No, coil resistance and electromagnetic thrust have obvious differences. Mixing different voltage models will lead to hydraulic pressure disorder or coil burnout and cannot be used interchangeably. |
| Q8 | How to quickly test coil integrity before installation? | Use a multimeter to measure coil resistance, normal range 14–15 ohms; infinite resistance represents open circuit, resistance below 10 ohms indicates internal short circuit and cannot be installed. |
