Failure Symptoms

Initial symptoms of a failing hydraulic component may include a slight delay in response from the controlled function or a minor decrease in hydraulic system pressure. If left unaddressed, this can lead to intermittent loss of control or increased heat generation within the hydraulic system. Continued operation risks significant performance degradation and potential damage to other hydraulic components.

Installation Tip

Ensure all hydraulic lines are properly flushed and free of debris before connecting them to the new component. Avoid cross-threading fittings, which can cause leaks and damage the component's ports.

Service Note

Inspect the hydraulic fluid level and condition, and check for any leaks in adjacent hydraulic lines or seals during replacement.
