Failure Symptoms

Initial symptoms of a failing gear pump may include a decrease in hydraulic system pressure or a slight increase in operating temperature. If ignored, the pump will progressively lose its ability to generate adequate flow and pressure, leading to significant loss of machine function and potential overheating. Continued operation risks damage to other hydraulic components due to insufficient lubrication and pressure.

Installation Tip

Ensure the pump shaft keyway is clean and the key is properly seated before mounting the pump. Avoid overtightening the mounting bolts, as this can warp the pump housing.

Service Note

Always replace the hydraulic filter and inspect the hydraulic fluid for debris or metal particles when replacing the hydraulic gear pump.
