Failure Symptoms

A failing main hydraulic pump will first manifest as a noticeable decrease in the speed and power of the excavator's hydraulic functions. If left unaddressed, the system may lose pressure, leading to an inability to perform essential digging or lifting operations. Continued operation risks overheating the hydraulic fluid and potentially damaging the pump and other hydraulic components.

Installation Tip

Before installing, ensure the hydraulic system has been completely flushed and the hydraulic filter replaced to prevent any debris from entering the new pump. Carefully align the pump shaft with the drive motor to avoid binding or damage.

Service Note

When replacing the main hydraulic pump, it is essential to inspect and replace the hydraulic filter and clean the hydraulic fluid reservoir.
