| No. | Question | Standard Answer |
|---|---|---|
| Q1 | Which backhoe loader fits transmission solenoid kit 25/220804 24V? | This 24V threaded cartridge transmission solenoid complete kit with bracket and bolt is specially manufactured for JCB 3CX and 4CX powershift backhoe loader transmission hydraulic system. |
| Q2 | What shift control function does this solenoid realize for powershift gearbox? | It receives ECU drive signal to adjust transmission control pressure, control shift valve spool stroke, realize stepless smooth automatic gear shifting for forward, reverse and speed gears. |
| Q3 | What abnormal transmission faults will occur if this solenoid fails? | Hard gear shifting, obvious jerk during shift, transmission slipping under load, unstable driving speed, delayed gear response and continuously high transmission oil temperature. |
| Q4 | Do I need to buy separate bracket and bolt during replacement? | No, this product is sold as a full assembly, matched galvanized mounting bracket and fixing bolt are included in the package, ready for direct installation without extra parts purchase. |
| Q5 | What durable design adapts to long-time construction site working conditions? | Multi-layer high temperature HNBR sealing rings, integral rust-proof metal valve body, fully sealed waterproof plug, matched galvanized anti-rust bracket, resist long-term hydraulic oil corrosion, vibration and high temperature. |
| Q6 | How to quickly check coil damage before installation? | Use multimeter to measure coil resistance, normal range 13–15 ohms; infinite resistance means open circuit, resistance lower than 9 ohms indicates coil short circuit and cannot be installed. |
