Failure Symptoms

A failing main hydraulic pump will first be evident by a significant reduction in the speed and power of all hydraulic functions, making the excavator feel sluggish. If the issue progresses, the hydraulic system may overheat rapidly due to internal leakage within the pump. Continued operation risks complete loss of hydraulic power, rendering the machine inoperable.

Installation Tip

Ensure the hydraulic tank is filled with the correct type and amount of hydraulic fluid before starting the engine. Never run the pump dry, as this can cause immediate internal damage.

Service Note

When replacing the main hydraulic pump, it is crucial to thoroughly flush the hydraulic system and replace the hydraulic filter and oil.
