Failure Symptoms

Early signs of a failing pump include a noticeable decrease in hydraulic system responsiveness and potential overheating. If left unaddressed, the machine may lose the ability to perform heavy-duty functions, leading to significant downtime. Continued operation risks severe damage to the entire hydraulic system due to insufficient lubrication and pressure.

Installation Tip

Always prime the new pump with clean hydraulic fluid before installation to ensure proper lubrication and prevent initial dry running. Avoid introducing any contaminants into the pump housing or hydraulic lines during the replacement process.

Service Note

Inspect the hydraulic tank and lines for any signs of internal wear or debris, and consider replacing the hydraulic filter.
