Failure Symptoms

Initial symptoms of a failing gear pump may include a slight decrease in hydraulic system pressure or a faint whining sound. If ignored, the pump will likely lose its ability to generate adequate pressure, leading to severely sluggish or non-functional hydraulic operations. Continued operation risks overheating the hydraulic fluid and damaging other system components.

Installation Tip

Ensure the hydraulic reservoir is clean and the fluid is free of contaminants before installation to prevent immediate damage to the new pump. Avoid overtightening the mounting bolts, as this can distort the pump housing.

Service Note

Inspect the hydraulic fluid and filter for contamination, and check the condition of the hydraulic lines and reservoir during pump replacement.
