This Maintenance Hydraulic Troubleshooting manual has become
the standard of excellence in hundreds of mills across the United States and
Canada over the past ten years. This manual is used in GPM's Maintenance
Basic Hydraulic Troubleshooting workshop to train many thousands of mechanics,
millwrights, pipe fitters, electricians and other maintenance personnel.
Almost 300 pages of informative, practical hydraulic troubleshooting information
are contained within its covers. Unlike most hydraulic books, this manual
contains the information that the hydraulic troubleshooter needs to know.
Whether the reader is a novice to hydraulics or an experienced veteran, the
information in this book will increase troubleshooting skills and increase
efficiency, both in parts cost savings and decreased down time by teaching the
concept of troubleshooting from the schematic. Even students who have
never seen a hydraulic schematic have learned to use them effectively to
troubleshoot very complex hydraulic machines. This
manual has literally turned thousands of parts changers into
troubleshooters. It is packed with valuable information that will save many times its cost,
including:
Hydraulic Fundamentals
- The basics of how hydraulics work. Applying the laws of physics in
an easy-to-understand manner for determining pressure, force, speed,
horsepower and cycle times. Why systems overheat and what can be done
about it.
Hydraulic Pumps
- How the pump works on the inside and the five time-saving ways to tell if
it needs to be replaced. The difference between a fixed and variable
displacement pump and the different troubleshooting techniques that should
be applied depending upon the type of pump. This section of the book
alone can save thousands of dollars the first time the techniques are used.
Directional Valves
- All different types of directional valves are discussed including their
proper schematic symbols and unique properties and applications.
Troubleshooting solenoids and valve spools, even two stage piloted valves,
all in a language that is easy to understand.
Check Valves
- How they are used and proper troubleshooting techniques. Includes a
discussion of spring loaded check valves and logic valves.
Pressure Controls
- A full discussion with illustrations and descriptions of the most common
of the pressure controls. Both normally open and normally closed
valves are covered along with the symptoms to look for when they fail.
Flow Controls
- Fixed orifice, variable orifice needle valves, pressure compensating and
temperature compensating flow controls are all discussed in detail including
meter-in, meter-out and bleed-off installations and how to diagnose problems
in them.
Accumulators
- The most dangerous hydraulic component. These powerful energy
storage devices are covered in depth including bladder, piston and diaphragm
accumulators, how to properly pre-charge them, how to tell when they have
failed, how to repair a piston, how to replace a
bladder (in detail) and detailed safety instructions.
Hydraulic Motors
- Single direction, bi-directional and radial piston designs are
covered. Symptoms to look for when a hydraulic motor fails and how it
will affect the operation of other motors in a machine when connected in
series or parallel and how the application determines if the motor should be
internally or externally drained. This section also contains a
discussion of crossport relief valves, brake valves and flow dividers.
Servo and Proportional
Valves - Never change a servo or proportional valve before
reading this section of the book. Complete instructions for diagnosing
problems before changing the valves and detailed discussion of how to change
these delicate valves without contaminating the system.
Hydrostatic Drive -
At last, an understandable discussion of the hydrostatic drive and how to
troubleshoot it. Explained in a way that the layman can understand,
the hydrostatic drive will no longer be a mystery to technicians after
reading this section.
Fluid Maintenance
- The functions of the fluid, its properties and how to take care of the
fluid for maximum oil life. Proper care and cleaning of the reservoir
and its associated components. Oil analysis, how to take the sample
and how to read the results. Filters and when they should be
replaced. Dirt alarms and why they should not necessarily be relied
upon. Leaks and their causes.
The most comprehensive, practical and easy-to-understand
hydraulic troubleshooting manual available anywhere at any price. This
book will pay for itself before the reader finishes it!
