Failure Symptoms

Early signs of a failing gear pump include a reduction in the speed and power of hydraulic functions. This can progress to audible noises such as whining or grinding, and potentially overheating of the hydraulic fluid. If left unaddressed, the pump can fail completely, resulting in a loss of hydraulic operation and potential damage to other system components.

Installation Tip

Ensure the hydraulic system is thoroughly flushed and clean before installing the new pump to prevent immediate contamination. Prime the pump with clean hydraulic oil before initial startup to avoid dry running.

Service Note

Replace the hydraulic filter element and inspect the hydraulic fluid for any signs of contamination or degradation.
