Basic Hydraulic Troubleshooting Workshops
Serving Industry Through Training, Troubleshooting and Reliability Since….
This three-day workshop is designed for electricians, millwrights, supervisors, reliability technicians and anyone who is responsible for the hydraulic maintenance of your plant machinery. Maintenance personnel look at hydraulics differently than engineers, salespeople, or manufacturers. This workshop is designed to include the five things a hydraulic troubleshooter needs to know:
- The function of all of the system components
- How to read and use the hydraulic schematic as a troubleshooting tool
- How to troubleshoot individual components, preferably without removing them from the machine
- How to properly adjust the system for maximum speed and efficiency
- The correct reliability checks to ensure machine longevity and uptime
The best time spent troubleshooting the machine is initially reading the schematic and making a good decision as to the cause of the problem.
This course is designed with the above concepts in mind. As the specific components are taught, the instructor refers the students to where they are located on their own in plant systems.

Hydraulic Fundamentals must be understood to troubleshoot hydraulics. One of the biggest problems in plants today is that the pressure is turned up to increase speed. If the system pressures are not properly set, the result can be excessive shock, leaks, and heat in the system. Hydraulic Pumps are usually the first components changed when a hydraulic problem occurs. The pump should never be changed before making the quick tests taught in this section. A step by step procedure is explained for setting the pump compensator and the system relief valve. Accumulators are the most dangerous hydraulic devices in the system. The proper method of bleeding the nitrogen and hydraulic pressure out of the accumulator before removing from the system is covered. The correct procedures for pre-charging and troubleshooting accumulators are explained in detail. Pressure Controls many times look similar but perform different functions in the system. This portion of the course covers the function, setting, and troubleshooting of all normally open and closed pressure controls. Directional Valves port the oil flow to cylinders and hydraulic motors as well as unload pumps and drain accumulators. The student learns the six main causes of solenoid failure. The symbols and use of two, three and four way valves are described. Fluid Maintenance is many times neglected or only receives attention when problems in the system occur. Oil sampling and filter maintenance practices are established. Reservoir maintenance standards for breathers, heaters, high temperature switches, level switches, etc. are specified. Hydrostatic Drives are commonly used on knucklebooms, cranes, planers, chemi-washers, centrifuges and conveyor drives. These drives are controlled both manually and with servo or proportional valves. The electrical amplifier and hydraulic adjustments for these drives are included in this session. Proportional Valves, Servo Valves and Linear Positioners are expensive and are in many cases changed without making any tests. The student learns the proper procedure for installing, adjusting, and troubleshooting these components. The Basic Hydraulic Troubleshooting course is a prerequisite to GPM’s Machine-Specific Hydraulic Troubleshooting workshop. To assess the knowledge of your maintenance personnel, you can administer our online hydraulics quiz. A score of less than 70% is a strong indicator that the Basic Hydraulic Troubleshooting workshop be attended first.
