Failure Symptoms

Initial signs of a failing hydraulic pump include a noticeable decrease in system responsiveness and power. If ignored, the pump will continue to degrade, leading to intermittent hydraulic failures and potential overheating of the hydraulic fluid. Continued operation with a faulty pump risks damage to other critical hydraulic components.

Installation Tip

Ensure the hydraulic reservoir is clean and free of debris before filling with fresh, specified hydraulic fluid. Avoid overtightening mounting bolts, as this can distort the pump housing and cause premature failure.

Service Note

Always replace the hydraulic filter element when installing a new hydraulic pump.
