At Dellinger Hydraulic Consulting llc., we are dedicated to providing the highest quality fluid power training services for our clients. With over 45 years of experience in the field, our team has become experts in hydraulic training, troubleshooting and providing practical advice on hydraulic system reliability.
Why choose our In-Plant Training over others?
Our hydraulic programs are truly one-of-a-kind! Unlike other companies that charge a whopping $1200 - $2000 per student, we offer a much more affordable option. In fact, we charge one flat rate for up to 20 students, which means that the more students you enroll, the more cost-effective it becomes per student. And that's not all! Our machine-specific program is taught on your in-plant hydraulic systems, which means that students get hands-on experience with the very systems they'll be working on. But that's not it! Our instructor, Alan Dellinger has over 35 years of experience in the hydraulics, and not just classroom experience, but real-life experience troubleshooting hundreds of actual hydraulic system problems. This means that students get to learn from a true expert who can provide real-life examples and insights. And to top it all off, a customized troubleshooting manual is first developed on your equipment and our instructor teaches the students how to use their own manuals for troubleshooting, so they can tackle any problem that arises with confidence. Don't miss out on this incredible opportunity to learn from the best and get hands-on experience with the very systems you'll be working on! Go to About to learn more about Alan.

Part 1 - Hands On
In-Plant 3-Day Basic Hydraulic Troubleshooting
This comprehensive 3-day workshop is specifically designed for electricians, millwrights, supervisors, and reliability technicians who are responsible for maintaining hydraulic systems. The workshop covers the five fundamental aspects that a hydraulic troubleshooter must know, including the function of each component, how to read schematic symbols, how to troubleshoot each component, how to properly adjust pressure for maximum efficiency, and the correct troubleshooting checks to make. The training program is designed to provide a hands-on troubleshooting experience in both the classroom and the plant. In the field exercise, the students will use some of the troubleshooting techniques learned in the workshop, on their actual systems. All of our courses are taught using layman terms and from a troubleshooting point of view, ensuring that participants can easily comprehend and apply the concepts covered.

Part 2 - Hands On
Customized In-Plant Machine Specific Hydraulic System Troubleshooting - Course Length 2 - 4 Days
This program involves conducting a thorough survey of the hydraulic system, which includes updating schematics and taking pictures of each component. The schematics are then redrawn to integrate the electrical control and hydraulic flow, and a detailed description is written for each component, outlining its function, troubleshooting, and adjustments. The training program is designed to provide hands-on experience in both the classroom and the plant, allowing students to gain a deep understanding of the in-plant' electrical and hydraulic function. Upon completion of the program, students will be equipped with the knowledge and skills necessary to troubleshoot hydraulic problems using their own troubleshooting manual.

In-Plant Hydraulic System Troubleshooting
If you are experiencing hydraulic problems that are causing unwanted downtime, you may be interested in our services. With more than 35 years of experience in hydraulic, troubleshooting, training, and consulting across a range of industries, including Paper Mills, Lumber, Plywood, LVL, OSB, Steel Mills, Tire Plants, Automotive Parts, and Power Plants, Alan can help you identify and resolve any issues you may be facing. Following a troubleshooting visit, Alan will hold a follow-up meeting with you and a detailed report outlining everything that was done and found during the visit.
In-Plant Hydraulic System Reliability Health Assessment

Ensuring the proper maintenance of your hydraulic system is paramount to its seamless operation and to avoid any unforeseen and costly downtime. However, many plants face the challenge of insufficient data to identify the root cause of failures, leading to a process of replacing parts until the issue is resolved. To circumvent this, our Dynamic Assessment process entails a meticulous and comprehensive analysis of various factors, including pressure settings, heat, pump and accumulator efficiencies, proper filtration, system design, and safety. We will diligently record all this information and furnish you with a comprehensive report that encompasses detailed recommendations to enhance your hydraulic system's performance. Furthermore, since many personnel may not be cognizant of all the checks that should be performed, the checks in the report can be utilized in your CMMS program. You can anticipate receiving this report after our follow-up meeting at your plant, where we will discuss the findings and recommendations in detail.
Troubleshooting Proportional Valves
Hands-On In-Plant Workshop
Course Length - 1 Day
5
Proportional valves are many times changed without any tests being performed. In addition, the adjustments on the amplifier or in the PLC are often made without consideration given to how the hydraulic system will be affected. This can be expensive, both in parts cost and plant downtime. In many cases, hours are spent just determining if there is an electrical or hydraulic problem. Students are actively involved in hands on exercises on the proportional valve trainer. After attending this 8-hour course, the maintenance personnel will know:
• The function of the three electrical signals fed into a proportional valve amplifier.
• The purpose of the LVDT (linear variable differential transformer) located on the proportional valve.
• How to check the LVDT feedback signal.
• How to mechanically and electrically null a direct operated valve.
• The function of the hydrostat when used with a proportional valve.
• The function of the lights and adjustments on the amplifier.
• How to check the power supply, enable, command and LVDT feedback signals.
• How to troubleshoot the direct operated proportional valve.
• The purpose and location of the Allen head plugs in a two-stage valve.
• How to convert externally piloted and drained valves into internally piloted and drained valves
• How to check the electrical inputs and outputs on a two-stage valve amplifier.
• How to electrically and mechanically null a two-stage valve.
• How the cylinders linear positioner operates.
• How to drive and troubleshoot a proportional valve with a test box.
