How to Change a Hydraulic Filter

Preparation

1. Understand the Hydraulic System: Familiarize yourself with the operating principles, operational procedures, and maintenance requirements of the hydraulic system.

2. Prepare a New Filter: Obtain a hydraulic oil filter that matches the original model according to the equipment manual.

3. Prepare Tools: Gather the tools necessary for dismantling and installing the filter, such as wrenches and screwdrivers.

4. Prepare a Container for Waste Oil: Use a container to collect any hydraulic oil that may leak during the replacement process.

5. Select a Suitable Location: Choose a flat and solid site to ensure the machine operates stably and without obstacles during the operation.

Replacement Steps

1. Release System Pressure:

• Turn off the engine and wait for the hydraulic system to completely stop working.

• Release the pressure in the hydraulic oil tank by opening the vent valve or loosening the relevant pipe joints.

2. Remove the Old Filter:

• Locate the hydraulic oil filter, which typically depends on the layout of the hydraulic system.

• Use appropriate tools to dismantle the filter, taking care to collect any leaked hydraulic oil.

3. Inspect the Old Filter:

• Observe the old filter for metal powder or other impurities, which may indicate wear or failure of hydraulic system components.

• If abnormalities are found, repair the hydraulic system before replacing the filter.

4. Install the New Filter:

• Clean the installation location of the filter to ensure no impurities or residues are present.

• Install the new filter in the designated location, ensuring a tight connection and no leaks.

• Use appropriate tools to tighten the filter, but avoid excessive force to prevent damaging the filter or related components.

5. Fill Oil and Bleed Air:

• After replacing the filter, add an appropriate amount of hydraulic oil to the hydraulic oil tank.

• Before filling the oil, ensure the hydraulic oil filter is correctly installed and has no leaks.

• After filling the oil, start the engine and run the hydraulic system to bleed out any air in the system.

• During the bleeding process, you can loosen the pipe joint on top of the main pump until stable hydraulic oil flows out.

6. Check and Test:

• Carefully inspect all components of the hydraulic system to ensure there are no leaks or abnormalities.

• Run the hydraulic system and observe its operating state for smoothness and the absence of abnormal sounds.

• If abnormalities are found, immediately stop the machine and investigate the cause.

Precautions

1. Safe Operation: Follow relevant safety operating procedures during the replacement of the hydraulic oil filter to ensure personal and equipment safety.

2. Keep Clean: Maintain a clean work area during the replacement process to prevent impurities from entering the hydraulic system.

3. Regular Inspection: It is recommended to regularly inspect and replace the hydraulic oil filter to ensure the normal operation of the hydraulic system and extend the equipment's service life.

By following these steps, you can successfully replace the hydraulic oil filter and ensure the normal operation of the hydraulic system.
