- Change Fluid If Necessary: If the fluid is old or contaminated, drain and replace it with the recommended type and grade of hydraulic fluid.
If the fluid appears to be in good condition, the next step is to check the hydraulic valves and solenoids responsible for the swing function. Hydraulic valves are sensitive to temperature changes, and problems may arise as the machine heats up.
- Check Valve Operation: Manually test the hydraulic valve that controls the swing function. Check for signs of wear, corrosion, or sticking. If the valve seems to be malfunctioning, it may need cleaning or replacement.
- Inspect Solenoids: Test the solenoids that control the hydraulic valves. Solenoids are electromagnetic devices that can fail due to overheating or wear. If a solenoid is faulty, it may only engage when the system is cold and fail as it warms up.
- Clean or Replace: If any valves or solenoids are dirty or damaged, clean or replace them as necessary.
Since the swing function is controlled electrically, inspect the wiring and connections related to the hydraulic solenoids.
- Check Wiring for Damage: Look for any frayed wires, loose connections, or corrosion on the electrical terminals. Pay particular attention to the connectors near the solenoids.
- Test Solenoid Activation: Use a multimeter to test whether the solenoid is receiving the correct electrical signal when the swing function is engaged. If the signal is weak or absent, there may be an issue with the control system.
- Clean and Repair: Clean any corroded connections and repair any damaged wiring. If the solenoid is not receiving power, trace the wiring back to the control panel or fuse box to find the source of the issue.
Hydraulic leaks can cause the system to lose pressure, which affects the swing function. Look for leaks around the swing motor, valves, and hoses.
- Inspect for Leaks: Check the hydraulic hoses and connections for signs of leaks. Pay attention to any wet spots or drips around the swing motor and valve.
- Test for Pressure Loss: If you suspect internal leaks, test the hydraulic system’s pressure with a gauge. If pressure drops significantly when the machine warms up, internal leakage could be the cause.
- Repair Leaks: Tighten any loose connections, replace any damaged hoses, and seal any leaks you find in the system.
If all else fails, it may be necessary to inspect the swing motor itself. A worn-out or damaged motor could be the reason for the intermittent operation.
- Test Motor Operation: Check if the swing motor operates smoothly when cold but struggles when warm. If the motor seems sluggish or jerky, it may be due for servicing or replacement.
- Inspect Internal Components: If possible, disassemble the motor to check for internal wear, such as damaged bearings or seals. If the motor has failed internally, it may need a complete overhaul or replacement.
