| No. | Question | Standard Answer |
|---|---|---|
| Q1 | Which construction machinery match 24V main pump solenoid valve 185-0008 1850008? | This cylindrical load sensing proportional solenoid fits 320D medium excavator and 120H/140H/160H motor grader hydraulic main pump regulator system. |
| Q2 | What core hydraulic function does this solenoid undertake? | It proportionally adjusts the swash plate angle of variable hydraulic pump, dynamically matches engine output power and hydraulic flow to avoid engine stall during heavy-load operation. |
| Q3 | What abnormal hydraulic faults will occur when this solenoid fails? | Insufficient digging/leveling power, unstable hydraulic pump pressure, obvious hydraulic jitter during composite action, and continuous abnormal high hydraulic oil temperature. |
| Q4 | Is full disassembly of the hydraulic main pump required during replacement? | No, integrated sleeve installation design, only remove the old solenoid and sleeve the new one on the pump valve cavity, no need to split the pump housing. |
| Q5 | What long-life anti-wear high-temperature resistant design? | The whole spool adopts ion nitriding hardening treatment, matched double HNBR oil-resistant high temperature sealing rings and fully sealed single-pin waterproof plug to resist long-term oil mist, dust and vibration. |
| Q6 | Are 185-0008 and 1850008 interchangeable spare part numbers? | Yes, the two codes correspond to the same complete main pump proportional solenoid assembly and can be replaced mutually. |
| 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. |
