Failure Symptoms

A failing hydraulic main pump will first present as a noticeable reduction in the speed and power of all hydraulic functions. If operation continues, the excavator will experience jerky movements, a significant loss of lifting capacity, and potentially overheating of the hydraulic system. Continued use with a compromised main pump risks severe damage to other critical hydraulic components, including valves and cylinders.

Installation Tip

Thoroughly flush the entire hydraulic system with clean fluid to remove any debris before installing the new pump, as contamination is a primary cause of premature pump failure. Ensure all hydraulic lines are properly connected and free of kinks before pressurizing the system.

Service Note

Replace the hydraulic filter element and inspect the hydraulic oil for any signs of contamination or wear particles when installing a new main pump.
