Failure Symptoms

The first indication of a failing hydraulic pump is often a noticeable decrease in the speed or power of hydraulic functions. If ignored, the pump's performance will continue to degrade, leading to overheating of the hydraulic fluid and potential cavitation noises. The ultimate consequence is a complete loss of hydraulic function, rendering the equipment inoperable.

Installation Tip

Ensure the hydraulic reservoir is filled to the correct level with the specified hydraulic fluid before attempting to prime and start the new pump. Never run the pump dry, as this can cause immediate internal damage.

Service Note

Always replace the hydraulic filter and inspect all hydraulic lines and seals when installing a new hydraulic pump.
