Failure Symptoms

A failing gear pump may initially manifest as a general decrease in hydraulic system responsiveness and power. As the wear progresses, implement speeds will slow down, and the system may become noisy due to internal leakage. Continued operation risks overheating the hydraulic fluid and potentially damaging other hydraulic components due to insufficient flow or pressure.

Installation Tip

Ensure the hydraulic reservoir is clean and the fluid level is correct before installation to prevent introducing contaminants. Do not install the pump if any damage is visible to the shaft or housing.

Service Note

Inspect the hydraulic filter and fluid for debris, and consider replacing the hydraulic fluid and filter element at the time of pump replacement.
