Failure Symptoms

Early signs of a failing gear pump include a noticeable reduction in hydraulic system pressure and slower implement response. If not addressed, this can lead to overheating of the hydraulic fluid and reduced overall machine productivity. Continued operation risks severe damage to other hydraulic components due to insufficient lubrication and pressure.

Installation Tip

Prime the new pump with clean hydraulic fluid before installation to ensure immediate lubrication and prevent dry start-up damage. Do not reuse the old mounting gasket; always install a new one to guarantee a proper seal.

Service Note

Replace the hydraulic filter and inspect the hydraulic fluid for contamination when installing a new gear pump.
