During this course, the primary emphasis will be on developing troubleshooting skills and mastering the inspection and testing procedures involved in a systematic approach to identifying malfunctions and their root causes. Participants will gain an understanding of the decision-making processes that form the foundation of an effective troubleshooting procedure. Additionally, several hands-on laboratory demonstrations will provide students with the opportunity to troubleshoot real-world system issues. Each application discussed in the course will be thoroughly analyzed through state-of-the-art animated programs. This will enable students to visualize the effects of recalibrating pressure, flow, torque, load, or adjusting component sizes.

Course Objectives:

Create and match a variety of hydraulic applications to the work to be performed
Properly test and inspect hydraulic systems
Diagnose system versus component problems
Distinguish problem “symptoms” from the actual “cause”
Apply a common-sense, systematic approach to troubleshooting
Evaluate the cause and effect of changing or re-sizing system components
Recommend and implement change towards fixing problems
