Case: Some Case excavators may use a similar solenoid valve. Verification required.
Installing a solenoid valve is a precision operation. Failure to follow these precautions can result in immediate damage to the valve, hydraulic contamination, or personal injury.
Verify Part Number: Ensure the new solenoid valve matches the old valve exactly. Check the voltage, connector type, and mounting configuration.
Cleanliness: The hydraulic system is highly sensitive to contamination. Clean the area around the valve before removal.
Hydraulic Oil: Check the hydraulic tank for debris or metallic particles. If the old valve failed catastrophically, the entire hydraulic system must be flushed.
Inspect Mating Parts: Check the valve block for wear, damage, or contamination. Check the electrical connector for corrosion or damage.
Check Electrical System: Verify that the correct voltage is supplied to the solenoid. Check fuses and relays.
Safety First: Ensure the machine is parked on level ground, the engine is off, and the hydraulic system is depressurized before beginning work.
Disassembly: Carefully disconnect the electrical connector and remove the old solenoid valve. Use proper tools to avoid damaging the valve block.
Cleaning: Thoroughly clean the valve block opening and surrounding area. Remove any debris or old seal material.
Inspection: Inspect the valve block bore for wear, scoring, or damage. If damaged, the valve block may need to be replaced or machined.
Seal Installation: Install new O-rings on the new solenoid valve. Lubricate with clean hydraulic oil.
Valve Installation: Carefully insert the new solenoid valve into the valve block. Ensure it seats properly.
Electrical Connection: Connect the electrical connector. Ensure it clicks into place and is secure.
Assembly: Tighten any retaining nuts or bolts to the specified torque.
This is the most critical step.
Fill Casing: Before starting the engine, ensure the hydraulic system is filled to the proper level.
Air Bleeding:
Start the engine at low idle.
Slowly operate the function controlled by the solenoid valve to circulate oil.
Check for leaks around the valve.
Electrical Test:
Turn the ignition on (engine off).
Activate the function controlled by the solenoid valve.
Listen for a "click" sound, indicating the solenoid is energizing.
Functional Test:
Start the engine and operate the function controlled by the solenoid valve.
Verify smooth and responsive operation.
Check for Leaks: Inspect all connections for leaks while the system is under pressure.
Final Check: Check the hydraulic oil level in the tank and top up if necessary.
Crush Hazard: The solenoid valve is part of a heavy hydraulic system. Ensure proper support is used.
High Pressure: Hydraulic fluid under pressure can penetrate the skin. Relieve pressure before disconnecting lines.
Hot Oil: Allow the system to cool before servicing.
Electrical Hazard: Disconnect the battery before working on the electrical system.
Pinch Points: Keep hands and fingers away from moving parts during installation.

Q1: What is the part number AT310584 exactly?
A: The AT310584 is a Hydraulic Solenoid Valve used in John Deere excavators and construction equipment. It is an electro-hydraulic component that controls hydraulic flow based on electrical signals from the machine's control system.
Q2: What does a solenoid valve do?
A: A solenoid valve is an electrically controlled valve. When the solenoid coil is energized, it creates a magnetic field that moves a plunger or spool, opening or closing hydraulic passages. This allows the machine's control system to direct hydraulic flow to various actuators.
Q3: What are the symptoms of a bad solenoid valve?
A: Symptoms of a bad solenoid valve include:
Loss of function: The controlled hydraulic function does not operate.
Erratic operation: The function operates inconsistently.
Error codes: The machine's computer may display a fault code.
No click sound: The solenoid does not energize when activated.
Overheating: The solenoid coil may become excessively hot.
Leaks: Hydraulic fluid may leak from the valve.
Q4: Can I replace just the solenoid coil without replacing the entire valve?
A: In some cases, yes. If the valve body is in good condition and only the coil has failed, the coil can be replaced separately. However, COGENG recommends replacing the complete valve assembly to ensure proper function and reliability.
Q5: What is the warranty period for this part?
A: Standard warranty for these hydraulic components is typically 6 to 12 months, depending on the supplier. However, warranty is void if the unit is disassembled, if the system was not flushed after a previous failure, or if the wrong hydraulic oil was used.
Q6: Can I use this solenoid valve on a different brand of excavator?
A: It is not recommended unless you are a qualified hydraulic engineer. While the valve might physically fit, the electrical characteristics and hydraulic flow requirements may not match the host machine's system, leading to poor performance or failure.
Q7: What type of hydraulic oil should I use?
A: Always use the oil specified by the equipment manufacturer. Typically, this is an ISO VG 46 anti-wear hydraulic oil. Using the wrong viscosity can cause overheating and internal damage.
Q8: Do I need to replace the hydraulic filter after installing a new solenoid valve?
A: Yes. It is highly recommended to replace the return filter and the suction filter immediately after installation. If the old valve failed, the system should be flushed with a flushing fluid, and the filters replaced again after 50 hours of operation.
Q9: What is the typical lead time for this part?
A: Lead times vary. Standard stock items may ship within 24-48 hours. Custom or non-stock items may take 15-30 days for manufacturing or sourcing.
Q10: How do I identify if I have a genuine OEM part or an aftermarket replacement?
A: Genuine OEM parts will have the John Deere logo and part number cast or stamped into the metal. Aftermarket parts may have the part number but lack the logo. COGENG parts are aftermarket replacements manufactured to meet or exceed OEM specifications. Always source from a trusted supplier.
Q11: What is the difference between AT310584 and other AT310 numbers?
A: The base number "AT310" indicates the series. The suffix (e.g., -584) indicates the specific revision, configuration, or application. Always match the complete part number.
Q12: Can I rebuild the solenoid valve instead of replacing it?
A: Yes, solenoid valves are rebuildable in some cases. However, it requires specialized tools, a clean environment, and technical expertise. Rebuilding is often more cost-effective than replacement if the core is in good condition. However, COGENG recommends replacing the complete valve for reliability.
Q13: How do I test a solenoid valve?
A: To test a solenoid valve:
Electrical Test: Use a multimeter to check the resistance of the solenoid coil. Compare to specification.
Power Test: Apply the correct voltage to the solenoid and listen for a "click" sound.
Hydraulic Test: Operate the controlled function and observe performance.
Leak Test: Inspect for external leaks.
Q14: What causes solenoid valve failure?
A: Solenoid valve failure can be caused by:
Electrical failure: Coil burnout, short circuit, or open circuit.
Contamination: Dirt or debris in the hydraulic fluid.
Wear: Internal wear of the spool or plunger.
Heat: Excessive heat causing coil insulation breakdown.
Vibration: Loosening of internal components.
Q15: Can I install this solenoid valve myself?
A: Yes, if you have mechanical and electrical experience and the proper tools. However, hydraulic systems are complex and can be dangerous. If you are unsure, consult a qualified mechanic.
