Failure Symptoms

Initial signs of failure may include a noticeable decrease in hydraulic system performance, such as slower bucket curl or boom lift. If left unaddressed, the pump's internal components can wear further, leading to intermittent operation and potential overheating of the hydraulic fluid. Continued operation with a failing pump risks damage to other critical hydraulic components.

Installation Tip

Ensure the hydraulic system is thoroughly flushed to remove any debris before installing the new pump. Avoid overtightening the mounting bolts, as this can distort the pump housing and cause premature failure.

Service Note

Inspect and clean the hydraulic system's intake screens and filters, and consider replacing the hydraulic fluid and filter elements.
