Even a reliable mobile hydraulic system will fail at some point. There are many reasons why it might happen. Contaminants in the fluid may be interfering with normal component functions. The machine may have been used beyond its design limits at some point. Scheduled maintenance may have been overlooked or a component such as a pump may have been operated past its expected service life.

One component in the system may turn out to be less durable than expected by the designers. These are just a few of the common reasons for system faults. Does your maintenance team have the most effective skills in hydraulic system maintenance and troubleshooting? If not, you may be spending too much on downtime and avoidable repairs. This in-depth course is designed to give you a clear understanding of hydraulic principles, component design, and functions needed to troubleshoot real-world hydraulics system failures.

The Troubleshooting Process is taught with the goal of eliminating the “hit or miss” methods that can be so costly in terms of time and materials. Safety is emphasized along with sound maintenance practices.
