Installation decomposition diagram
| Step | Action | Visual Cue / Component | Torque / Specification |
|---|---|---|---|
| 1 | Preparation | Clean work area; relieve hydraulic pressure | Safety first: Wear gloves and glasses. |
| 2 | Removal | Disconnect the DIN electrical connector | Cable socket attached to Item 8. |
| 3 | Extraction | Unscrew and remove the old valve from the manifold | Use 32mm or 36mm wrench on the valve body hex. |
| 4 | Seal Inspection | Remove old O-rings from the manifold port | Ensure no debris enters the hydraulic system. |
| 5 | Pre-Fitting | Lubricate new O-rings (Item 6) with clean hydraulic oil | Fit seals onto the new COGENG valve (Item 1). |
| 6 | Installation | Screw the new valve into the manifold hand-tight | Then torque to 40-50 Nm (standard recommendation). |
| 7 | Coil Orientation | Verify the solenoid coil (Item 1) can rotate freely | Adjust coil position if needed, then tighten nut (Item 2) to 5-7 Nm. |
| 8 | Connection | Attach the DIN connector (Item 8) and test function | Ensure voltage is 24V DC and function is correct. |
Frequently Asked Questions
| FAQ Topic | Question | Answer |
|---|---|---|
| Compatibility | Will this fit my Liebherr 314? | Yes. Part numbers 5615344 and 5614032 are direct fits for Liebherr 309, 311, 312, 313, and 314 excavator models. |
| Cross-Reference | Are 5615344 and 5614032 different? | They may have slight differences in spool configuration or connector orientation. Please check your machine's serial number or old part to ensure you order the correct COGENG reference. |
| Durability | What makes this a "high flow" durable replacement? | COGENG valves use hardened steel spools and Viton seals. They are tested to meet or exceed OEM flow and pressure ratings, ensuring long service life under demanding cycles. |
| Installation | Is it plug-and-play? | Yes, it is a direct OEM replacement. Just clean the surface, replace the seals, screw it in, and connect the DIN plug. No programming is needed. |
| Troubleshooting | The coil gets hot or the valve buzzes. Is this normal? | A warm coil is normal (continuous duty). Loud buzzing usually indicates dirt in the valve or low voltage (<20V). Check the hydraulic oil cleanliness and battery voltage. |
| Shipping | How fast is "fast shipping"? | Orders placed before 2 PM are typically shipped the same day. We ship globally via DHL/FedEx, with typical delivery in 3-7 business days. |
