Failure Symptoms

Initial signs of failure include a noticeable decrease in hydraulic system performance, such as slower boom or bucket movements. If left unaddressed, the pump's efficiency will continue to degrade, leading to intermittent loss of hydraulic function. Continued operation with a failing pump risks damage to other critical hydraulic components due to inadequate lubrication and pressure control.

Installation Tip

Ensure the hydraulic reservoir is clean and the fluid level is correct before beginning installation. Avoid overtightening the mounting bolts, as this can distort the pump housing and cause premature failure.

Service Note

It is recommended to inspect and replace the hydraulic filter element and check the hydraulic fluid condition when servicing the vane pump group.
