Failure Symptoms

Initial signs of failure may include a noticeable decrease in the speed or force of hydraulic functions. If ignored, the problem can escalate to intermittent loss of hydraulic power, making the equipment difficult to control. Continued operation with a failing component risks damage to other hydraulic system parts due to improper pressure or flow.

Installation Tip

Ensure the work area is clean to prevent contamination of the hydraulic system during installation. Avoid overtightening mounting bolts, as this can distort the component or damage sealing surfaces.

Service Note

Inspect hydraulic fluid for debris and check associated seals and hoses for wear or leaks when replacing this component.
