| No. | Question | Answer |
|---|---|---|
| Q1 | Which excavator & pump fit manifold 719753 /719754 /420-001927? | Fits 225-7/R225-7 with K3V112 hydraulic pump, 24V yellow two-pin plug. |
| Q2 | Core function of this pump solenoid manifold? | Adjust pump displacement to control digging power and realize energy-saving load sensing. |
| Q3 | Common hydraulic faults caused by damaged valve block? | Weak digging force, unstable idle, high fuel consumption and hydraulic oil leakage. |
| Q4 | Need to split hydraulic pump during replacement? | No, unified mounting flange, direct bolt installation without pump disassembly. |
| Q5 | Wear & high temperature resistant structural design? | Cast steel valve block, ion nitriding hardened spool, H-grade pure copper coil, double HNBR sealing rings. |
| Q6 | Are 719753,719754,420-001927 fully interchangeable? | Yes, all three OE numbers belong to one complete hydraulic pump solenoid manifold assembly. |
| Q7 | How to test coil condition before installation? | Measure coil resistance 14.1–14.7Ω; infinite resistance = open circuit, below 10Ω = short circuit. |
