Failure Symptoms

The first indication of a failing hydraulic pump is often a gradual decrease in the speed and power of hydraulic functions. This may progress to intermittent operation, excessive noise (whining or grinding), and eventually a complete loss of hydraulic pressure. The consequence is significant operational impairment and potential damage to other hydraulic components.

Installation Tip

Thoroughly flush the hydraulic system and ensure all lines are clean before installing the new pump to prevent immediate contamination. Never run the pump dry; ensure it is fully primed and submerged in hydraulic fluid before initial startup.

Service Note

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