Failure Symptoms

The first indication of a failing Pump Gp may be a noticeable decrease in hydraulic system speed or power, such as slower bucket curl or lift. If the issue progresses, hydraulic functions may become erratic or cease entirely, impacting the machine's operational capability. Continued use with a failing pump can lead to overheating of the hydraulic fluid and potential damage to other system components.

Installation Tip

Ensure all hydraulic lines are properly flushed and free of debris before connecting them to the new pump assembly. Avoid rotating the pump shaft by hand if it feels stiff or binds, as this could indicate internal damage.

Service Note

Inspect and replace the hydraulic system filter and clean the hydraulic oil reservoir during the pump replacement.
