Failure Symptoms

A failing hydraulic gear pump may initially exhibit a loss of hydraulic power, making controls feel sluggish or weak. If the issue progresses, the pump may start to make audible whining or grinding noises, and hydraulic fluid may overheat due to internal leakage. Continued operation with a failing pump can lead to complete loss of hydraulic function and potential damage to other hydraulic components.

Installation Tip

Ensure the hydraulic system is completely clean before installing the new pump; any debris can quickly damage the precision gears. Prime the pump according to the manufacturer's instructions before starting the engine.

Service Note

Replace the hydraulic filter and inspect the hydraulic fluid reservoir and lines for contamination when installing a new hydraulic gear pump.
