Failure Symptoms

The initial indication of a failing main hydraulic pump is a significant loss of power and speed across all hydraulic functions, making the excavator feel sluggish. Continued operation can lead to overheating of the hydraulic oil and potential internal pump damage, characterized by whining or grinding noises. The worst-case scenario is a complete loss of hydraulic pressure, halting all machine operations.

Installation Tip

Before installation, ensure the hydraulic reservoir is thoroughly cleaned and that all hydraulic lines are free of debris. It is crucial to prime the new pump with clean hydraulic fluid before initial startup to prevent dry running and damage.

Service Note

Always replace the hydraulic filter and inspect the hydraulic fluid for any signs of contamination or metal particles when servicing the main hydraulic pump.
