Failure Symptoms

Initial signs of a failing hydraulic pump include a noticeable decrease in system responsiveness and increased cycle times for hydraulic functions. If left unaddressed, the pump's performance will continue to degrade, leading to intermittent loss of hydraulic power and potential overheating of the hydraulic system.

Installation Tip

Ensure the hydraulic reservoir is filled with the correct fluid type and level before starting the pump to prevent dry running. Avoid overtightening the mounting bolts, as this can distort the pump housing.

Service Note

Inspect and replace the hydraulic filter and strainers, and check the hydraulic fluid for signs of contamination.
