| Q1 | Which CAT excavator fits 24V main pump coil 4I-5674 4I5674? | This LS proportional solenoid coil is specially designed for CAT E320, also compatible with E312, E315, E320L C-series excavators equipped with Kawasaki main pump. |
| Q2 | What is the power matching principle of this solenoid coil? | It outputs proportional magnetic force according to ECU signal to adjust pump swash plate angle, balance engine load and hydraulic output, and prevent engine stall during heavy load excavation. |
| Q3 | What machine failures will be caused if this coil burns out? | Severe loss of digging power, unstable pump pressure, jitter during operation, slow movement of boom and arm, and continuously rising hydraulic oil temperature. |
| Q4 | Is it necessary to disassemble the entire hydraulic main pump to replace this coil? | No, the coil adopts sleeve installation structure; just pull out the old coil directly from the valve core and install the new one, pump disassembly is not required. |
| Q5 | What anti-aging sealing process adapts to harsh pump cabin environment? | Multi-layer high-temperature insulation paper + full epoxy encapsulation, anodized anti-rust aluminum shell, fully sealed two-pin waterproof plug, resist long-term oil mist, high temperature and vibration erosion. |
| Q6 | Can this 24V coil be replaced with a 12V coil of the same model? | No, the internal resistance and output magnetic force are different, mixing 12V and 24V coils will cause unstable pump pressure or coil burnout, cannot be interchanged. |
| Q7 | How to quickly judge coil damage before installation? | Use a multimeter to measure coil resistance, normal range 13–14 ohms; infinite resistance means open circuit, resistance below 10 ohms indicates internal short circuit and cannot be installed. |
