| No. | Question | Standard Answer |
|---|---|---|
| Q1 | Which excavators fit main pump proportional coil 086-1879? | This galvanized LS proportional solenoid coil is specially manufactured for E320B, also compatible with E110B, E120B, E200B, EL200B B-series hydraulic excavator main pump regulator valve. |
| Q2 | What power matching function does this coil realize for main pump? | It generates proportional magnetic force according to ECU signal to push valve spool, adjust pump displacement in real time based on excavation load, balance engine load and reduce fuel consumption during long-hour heavy work. |
| Q3 | What machine failures will be caused if this coil burns out? | Severe power loss under heavy digging, frequent engine stall, unstable pump pressure, slow boom & bucket movement, fluctuating idle speed and continuous high hydraulic oil temperature. |
| Q4 | Do I need to remove the whole hydraulic main pump to replace this coil? | No, just pull out the old coil sleeve from the valve core directly, install the new coil and plug the green connector, pump disassembly is not required, maintenance efficiency is greatly improved. |
| Q5 | What anti-aging sealed design adapts to harsh pump cabin environment? | Multi-layer high temperature insulation paper + epoxy full sealing, galvanized anti-rust outer shell, fully sealed green two-pin waterproof plug, resist long-term hydraulic oil mist, high temperature and vibration erosion. |
| Q6 | How to quickly judge coil damage before installation? | Use multimeter to measure coil resistance, normal range 12–14 ohms; infinite resistance means open circuit, resistance below 9 ohms indicates internal short circuit and cannot be installed. |
