The following are recommended practices for hydraulic filter servicing and handling. These steps are universal to many hydraulic systems. This servicing information is provided as a best practices guide. Donaldson recommends that you follow the filter service instructions supplied by your original equipment manufacturer. These recommended practices are not intended to replace or supersede the service instructions supplied by your equipment or vehicle manufacturer.
  1. Check the filter service indicator
    Check to see that the OEM specified service interval has been reached or that the service indicator shows that the filter is due for servicing.

  2. Turn system off and release pressure
    Ensure that the hydraulic system is turned off.
    Check that there is no pressure present.

  3. Remove the cartridge housing

  4. Remove the used filter and gasket, if applicable
    Properly dispose of the cartridge according to local regulations.

  5. Clean the head seal area and housing
    Clean out any sediment from the inside of the filter housing.

  6. Inspect the new filter cartridge for damage
    Check the new filter you will be installing for any shipping and handling damage. Do not install a damaged filter.

  7. Install and lubricate seals, gaskets and threads. 
    Lubricate the o-rings, gaskets, housing seals and threads with clean system oil.

  8. Install new cartridge into the housing

  9. Align threads. Spin filter until gasket contacts
    Fit the housing to the filter head as instructions on the housing.
