Failure Symptoms

A failing hydraulic filter may first present as a slight hesitation or reduced speed in hydraulic functions. If left unaddressed, this can progress to jerky movements, increased fluid temperature, and audible signs of pump strain. The ultimate consequence of a blocked filter is severe wear on hydraulic components and potential system failure.

Installation Tip

Ensure the sealing surface on the filter head is clean and smooth before installing the new filter. Do not reuse the old O-ring seal; always install a new one with the filter.

Service Note

Inspect the hydraulic fluid for discoloration or debris, and check the condition of the hydraulic pump and cylinders when replacing this filter.
