Failure Symptoms

Initial signs of a failing hydraulic filter include a slight increase in hydraulic system temperature or a subtle degradation in cycle times. If ignored, the filter will become completely blocked, leading to a bypass condition where unfiltered fluid circulates, accelerating wear on all hydraulic components. Eventually, this can result in significant hydraulic system malfunction and costly repairs.

Installation Tip

Ensure the filter housing is clean before installing the new filter to prevent debris from entering the hydraulic system. Do not overtighten the filter, as this can damage the seal or housing.

Service Note

Inspect the hydraulic oil for contamination and check the condition of the hydraulic pump and cylinders when replacing the filter.
