Failure Symptoms

Initial signs of a failing vane pump include a noticeable decrease in hydraulic system performance, such as slower operation of actuators or reduced lifting capacity. If left unaddressed, the pump's efficiency will continue to degrade, leading to intermittent hydraulic failures and potential overheating of the hydraulic fluid. Continued operation with a failing pump risks damage to other critical hydraulic components.

Installation Tip

Thoroughly flush the hydraulic system to remove any debris before installing the new pump. Avoid overtightening the mounting bolts, as this can distort the pump housing and lead to premature failure.

Service Note

Inspect the hydraulic fluid reservoir and filters for metal shavings, which can indicate internal wear in the old pump.
