Failure Symptoms

A failing gear pump may initially cause a slight decrease in hydraulic system responsiveness or power. If ignored, this can progress to intermittent loss of hydraulic pressure, making implements slow, weak, or unresponsive, potentially leading to an inability to complete work cycles. This impacts productivity and can cause delays.

Installation Tip

Ensure the pump's inlet and outlet ports are clean and free of debris before connecting hydraulic lines to prevent internal damage. Do not rotate the pump shaft by hand if it feels stiff or binds, as this may indicate internal damage.

Service Note

When replacing a hydraulic gear pump, it is crucial to inspect and replace the hydraulic filter element and check the condition of the hydraulic fluid.
