VOE14555190 — Main Hydraulic Pump Voe14555190 For Volvo Excavator Ec140C

This is a main hydraulic pump, the primary component responsible for generating the flow and pressure needed to operate all hydraulic functions on the excavator. It is manufactured to high standards using precision-engineered internal parts for maximum efficiency and durability, unlike a worn or failing pump. Operators will typically experience a significant loss of power, slow or non-responsive hydraulic movements, and increased cycle times when this main hydraulic pump fails.

Failure Symptoms

The first noticeable symptom of a failing main hydraulic pump is a general loss of hydraulic power and slower operation of all functions. If ignored, the pump's output will continue to decrease, leading to intermittent hydraulic failure and potentially overheating of the hydraulic system. Continued operation risks severe damage to other hydraulic components due to lack of lubrication and pressure.

Installation Tip

Before installing the new pump, ensure the hydraulic system has been thoroughly flushed to remove any contaminants that could damage the new pump. Never run the pump dry; always prime it with hydraulic fluid before connecting the lines and starting the engine.

Service Note

When replacing the main hydraulic pump, it is crucial to replace the hydraulic filter and inspect the hydraulic fluid for any signs of metal particles or contamination.
