Maintenance Hydraulic Quiz
The quiz below should be administered to all maintenance personnel responsible for
hydraulic equipment. A score of less than 80% is a strong indication that GPM’s
Maintenance Hydraulic Troubleshooting workshop could reap significant savings in
unnecessary parts changing and plant downtime.
It is recommended that any student who achieves less than 70% on this quiz attend our
Maintenance Hydraulic Troubleshooting workshop.
Troubleshooting In-Plant hydraulics
The Textbook
Our Troubleshooting In-Plant Hydraulics workshops are designed and taught on the
actual systems at your plant. First, all of the systems you chose to be customized are
redrawn from the original prints. Shop prints are fine for certain applications. The
troubleshooting schematics produced by GPM show the machine in various stages of
operation, integrating the electrical control with the hydraulic flow. A commentary is
written, describing the characteristics and troubleshooting operation of each component.
All of this information is complied into a textbook that the student gets to keep as
reference material.
Prior to attending the Troubleshooting In-Plant Hydraulics course, it is recommended
that technicians attend our Maintenance Hydraulic Troubleshooting workshop. To
determine if your maintenance personnel need our first session, have them take our
Online Hydraulics Quiz.
The Class
The classroom training is unlike any other maintenance instruction the student has ever
attended. Intense, practical training delivered by an experienced instructor who is able
to provide real life examples and specific troubleshooting techniques keeps the class
interesting and informative. In addition to classroom lecture, approximately half the time
will be spent providing hands-on instruction out in the facility on the very equipment the
students are familiar with. At the conclusion of the class, the student will understand the
in-plant systems and will know what troubleshooting and preventive checks to make on
the machine.
“Not only do the ones who attended have a better understanding of our hydraulics, they
know how to troubleshoot problems, have an excellent set of books on the systems, and
learned a systematic troubleshooting procedure that can be applied to most
maintenance problems, hydraulic or otherwise.”
Donald Houston
Maintenance Training Coordinator
International Paper

“This class received the highest reviews of all maintenance classes conducted. We
have already seen the material learned put into practice by maintenance personnel who
are becoming troubleshooters and not just part changers.”

It is recommended that all students attend the Maintenance Hydraulic
Troubleshooting class prior to attending the In-Plant Hydraulics course.
This three-day course is designed for electricians, millwrights, supervisors, and anyone
who is responsible maintenance of your plant machinery. Maintenance personnel look
at hydraulics different than engineers, sales people, or manufacturers. This workshop is
designed on what the maintenance person needs to know:




The function of each hydraulic component.
How to troubleshoot the component.
How to read the hydraulic symbols that are found on the hydraulic schematic.
How to set the system pressures.
The best time spent troubleshooting the machine is initially reading the print 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 student to where they are located on the in-plant
systems.
Program
Hydraulic Fundamentals must be understood to troubleshoot hydraulics. The biggest
problem in plants today is that the pressure is turned up to increase speed. If the
system is 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 specifically covered. Accumulators used for both volume
and shock applications are discussed.
Pressure Controls all look very 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, log cranes, and slasher
conveyors. These drives are controlled both manually with servo or proportional valves.
The electrical amplifier and hydraulic adjustments for these drives are included in this
session.
Servo Valves and Linear Positioners. These valves are expensive and are in many
cases changed without making any tests. The student learns the proper procedure for
installing, adjusting, and troubleshooting these valves.
The Maintenance Hydraulic Troubleshooting course is a prerequisite to GPM’s
Customized Troubleshooting In-Plant Hydraulics.
