Hydraulic System Troubleshooting

Step By Step Testing and Solutions for Hydraulic System Failures

Hydraulic system failures may show similar symptoms: a gradual or sudden loss of pressure or flow resulting in loss of power or speed in the cylinders or hydraulic motors. In fact, the cylinders may stall under light loads or may not complete the stroke. Often the loss of power is accompanied by an increase in pump noise, especially as the pump tries to build up pressure.

Any major component (pump, relief valve, directional valve, proportional valve or cylinder) could be at fault. In a sophisticated system other components could also be at fault, but this would require the services of an experienced technician.

By following an organized step-by-step testing procedure, the problem can be traced to a general area, then if necessary, each component in that area can be tested or replaced.
