Troubleshooting Hydraulic Components Using Leakage Path Analysis Methods -

In 1990, Rory McLaren, the Director and Founder of the Fluid Power Safety Institute™ decided to do something about the lack of standards for testing fluid power components. He could not understand why, for example, there was a "standard" technique for testing pumps, yet it seemed that each pump or machine manufacturer that wrote information about pump testing would put a different "spin" on it.

In fact, Rory believes that a vast number of pump test recommendations in print today are, extremely unsafe, erroneous, or both. In addition, he found that testing procedures for certain components, for example, pressure control valves, check valves, and directional control valves,
were simply unavailable - certainly from the point of view of safety!

In the planning stages of writing the book, Rory set himself a number of objectives:
1. The foundation of every test procedure had to be safety.
2. Every test procedure had to be tried and proven.
3. At least 75% of the tests had to be facilitated with the machine at full lockout.
4. The majority of the tests had to be facilitated on-board the machine.
5. The diagnostic instrumentation for the tests had to be safe, reasonably priced, and user-friendly.

Rory spent a decade pioneering tests for components that were traditionally removed from the machine for testing. Component removal invites opportunity for accidents, is extremely counterproductive, and is economically devastating. Thus, Rory developed a unique technique for testing the vast majority of fluid power components which he appropriately called "pressure/leak" testing. It is safe, simple, and highly effective!

About the Book
The book has approximately 480-pages, measures approximately 8.5" X 11," and has a soft cover. It has thirteen chapters covering the following topics:
1. Safety.
Troubleshooting Hydraulic Components Using Leakage Path Analysis Methods
2. System Start-up Procedures and Troubleshooting.
3. Procedures for Testing Hydraulic Pumps.
4. Procedures for Testing Pressure Control Valves.
5. Procedures for Testing Industrial Directional Control Valves.
6. DO8 and D10 Directional Control Valve Conversion Procedures.
7. Procedures for Testing Mobile Directional Control Valves.
8. Procedures for Testing Hydraulic Cylinders.
9. Procedures for Testing Hydraulic Motors.
10. Procedures for Testing Cartridge Valves.
11. Procedures for Testing Flow Control Valves.
12. Procedures for Testing Check Valves.
13. Safety with Accumulators.

Each test procedure explains:
a. Exactly what the procedure will accomplish.
b. Safety procedures and considerations.
c. How to prepare for the test and what diagnostic equipment is needed.
d. Step-by-step test procedures with illustrations and graphs showing the correct location of the diagnostic equipment, and example graphs showing what the test results should be when a component is in good working condition.
e. A guide to help analyze the test results, each showing three scenarios:
1) An acceptable outcome.
2) A marginal outcome.
3) An unacceptable outcome.

In addition, blank test/performance charts are located throughout the book for the user to copy and use.

This book is not intended for untrained personnel. It is written for trained, authorized personnel who have been suitably trained in fluid power, have the proper diagnostic instruments, and know how to use them.

If you attempt to troubleshoot fluid power systems and/or components without proper training you could get severely injured or killed!
