Step 3: Test the Hydraulic System
If the system is slow or unresponsive, operate the machine to identify any irregularities. Check for any abnormal sounds coming from the pump or cylinders. If the machine is struggling to lift or perform tasks at full capacity, there may be an issue with the hydraulic pump or fluid contamination.
Step 4: Inspect the Hydraulic Fluid
Take a sample of the hydraulic fluid and check its condition. If the fluid appears dirty, contaminated, or has an unusual color, it may need to be replaced. Contaminated fluid can damage the pump, valves, and seals, reducing system efficiency.
Step 5: Check the Pump and Seals
Inspect the hydraulic pump for wear. A worn-out pump will not generate the required pressure, leading to poor system performance. Also, inspect the seals in the hydraulic cylinders, as damaged seals will allow fluid to leak out and reduce pressure.
Fixing Common Hydraulic Problems in the AW Super 200
Once you’ve diagnosed the issue, it’s time to address the problem. Below are some recommended solutions to common hydraulic issues:
1. Replacing or Rebuilding the Hydraulic Pump
If the hydraulic pump is worn out or damaged, it may need to be rebuilt or replaced. A faulty pump can lead to insufficient hydraulic pressure, resulting in poor system performance. Replacing the pump is a complicated task and may require professional assistance.
2. Repairing or Replacing Leaking Hoses and Seals
Leaking hydraulic hoses or seals should be replaced immediately to prevent fluid loss. For hoses, inspect them for any cuts, abrasions, or cracks. For cylinder seals, ensure you use high-quality seals that are designed to last under heavy pressure.
3. Flushing and Replacing Hydraulic Fluid
If the fluid is contaminated, flush the system to remove the dirty fluid and replace it with fresh, clean fluid. Regular fluid changes are essential to maintaining the efficiency of the hydraulic system. Be sure to use the correct fluid for your specific machine.
4. Bleeding the Hydraulic System
If there is air in the system, it must be bled out to restore proper operation. Follow the manufacturer’s instructions to bleed the system, ensuring that all air is removed from the lines.
5. Checking the Cooling System
If overheating is an issue, inspect the hydraulic cooler for clogs or damage. A dirty or clogged cooler prevents proper heat dissipation, which can lead to fluid breakdown. Ensure the cooler is clean and in good working condition.
