Failure Symptoms

The first indication of a failing gear pump might be a noticeable decrease in hydraulic system pressure or slower implement response. If ignored, this can lead to a complete loss of hydraulic function and potential overheating of the hydraulic fluid. Continued operation risks severe damage to the pump and other hydraulic components.

Installation Tip

Prime the new gear pump with clean hydraulic fluid before installation to ensure immediate lubrication and prevent dry start-up. Avoid installing the pump with any side-load on the shaft, as this can lead to premature bearing failure.

Service Note

Thoroughly flush the hydraulic system and inspect the hydraulic filter for debris before installing the new pump.
