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.

Spin-On Filter Servicing

  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. Unscrew and remove old filter and gasket.
    Properly dispose of the filter as may be required by local regulations or recycle it.

  4. Wipe filter head with clean cloth.
    Clean the filter head or cover surfaces. When performing a hydraulic oil change, it is best to use a clean cloth.

  5. Inspect the new filter for damage.
    Check the new filter you will be installing for any shipping and handling damage. Do not install a dented filter since the canister has been weakened.

  6. Lubricate the threads.
    Lubricate threads of filter head.
    Failure to do this could result in thread galling.

  7. Apply thin film of clean motor oil to gasket.
    Lubricate seal(s) with clean system oil.

  8. Align threads. Spin filter until gasket contacts.
    Spin the new filter on until the top of the gasket first contacts the sealing surface.

  9. Hand tighten the filter.
    Tighten per the guidance of the icons which appear on the filter housing. Do not over-tighten.

  10. Bleed the system and check for leaks.
