Failure Symptoms

Initial symptoms of a failing hydraulic pump include a noticeable decrease in the speed and power of hydraulic functions, such as lifting or digging. If ignored, the pump may eventually fail to generate sufficient pressure, leading to a complete loss of hydraulic operation. This can result in significant operational downtime and inability to perform work.

Installation Tip

Ensure the hydraulic system is completely free of air after installation by following the manufacturer's priming procedure. Avoid running the pump dry, even for a short period, as this can cause immediate damage.

Service Note

Inspect and replace the hydraulic filter element and check the hydraulic fluid level and condition when replacing the hydraulic pump.
