Failure Symptoms

The first indication of a failing gear pump is typically a reduction in hydraulic system speed and power. As the pump wears, hydraulic functions will become progressively slower and weaker, and the operator may hear unusual noises like whining or groaning from the pump. Continued operation with a worn pump can lead to overheating of the hydraulic fluid and potential damage to other critical hydraulic components.

Installation Tip

Ensure the hydraulic system is completely clean and free of any debris before installing the new pump to prevent immediate damage. Never run the pump dry; prime it according to manufacturer recommendations before initial startup.

Service Note

Inspect the hydraulic fluid reservoir and filters for metal particles, and check all hydraulic hoses and seals for leaks during the pump replacement.
