Hydraulics Training -- Construction/Agricultural - 5 Video Set - (Darlington for sale in Charleston, South Carolina

This is a set of five slightly used VHS videos that provide excellent training in servicing, maintaining and troubleshooting hydraulic systems on construction and agricultural equipment. This set offers a wealth of learning and includes all five of the following videos:
1. Fundamentals of Hydraulics and Troubleshooting
This video provides an excellent visual introduction to hydraulic systems and many of the problems they can develop. Developed and produced in partnership with major hydraulic equipment manufacturers, Fundamentals of Hydraulics & Troubleshooting explains the fundamentals of hydraulic systems and demonstrates industry-accepted practices for diagnostics and troubleshooting.
Topics covered include:
• Safety procedures for working on hydraulic equipment
• Reservoir design and construction
• Hydraulic fluids
• Pumps
• Directional control valves
• Relief valves
• Cylinders
• Cavitation and aeration
• Common causes of slow cycle times
• Diagnostic testing
Color animations are used to explain:
• How hydraulic pumps create flow and resistance to flow creates pressure
• Operating principles of external gear, internal gear, vane, axial piston and radial piston pumps
• Function of open center, closed center and cylinder circuits
• Importance of proper reservoir design
• How suction strainers cause cavitation at the pump inlet
• Operation of direct-acting and pilot-operated relief valves
The following diagnostic tests are explained and demonstrated:
• Direct pump test (pump flow test)
• System "T" test (system load test)
• Spool valve leakage test
• Cylinder piston seal leakage test
2. Advanced Hydraulics and Troubleshooting
A perfect follow-up to Fundamentals of Hydraulics & Troubleshooting, this video provides advanced instruction on the diagnostic process and procedures needed to competently troubleshoot common hydraulic problems. This video, produced by the Kubota Tractor Corporation, covers four case studies representing the most common types of hydraulic service calls technicians encounter on hydraulically powered equipment. The viewer is challenged to develop their own diagnosis before the cause of each problem is explained. The video illustrates common mistakes technicians make when diagnosing hydraulic problems and shows how to avoid them.
The following diagnostic tests are applied to actual problems, and the technician's interpretation of the results is analyzed and explained:
• Direct pump test (pump flow test)
• System "T" test (system load test)
• Spool valve leakage test
• Cylinder piston seal leakage test
3. Hydraulic Symbols
This video was produced to teach the technician/student how to read hydraulic schematics. The video uses line drawings and cut-away views to illustrate how symbols are used to represent hydraulic components. Animations are used to explain how visualization is employed to understand the operating function of a component represented by a one-dimensional symbol. Once these concepts are understood, hydraulic circuit drawings become easier to understand.
The following symbols are illustrated and explained:
• Reservoirs
• Lines, tubes, hoses
• Enclosures and connections
• Pumps, fixed and variable, pressure compensated and manual control
• Motors
• Cylinders - with and without cushions
• Pressure relief, pressure reducing and sequence valves
• Directional control valves
• Flow control valves, fixed and adjustable, pressure and temperature compensated
• Filters, coolers, heaters and accumulators
4. Hydrostatic Fundamentals
This video was produced for training technicians on heavy-duty hydrostatic transmissions.
Topics covered include:
• Transmission components - pump, motor, charge circuit and control
• Axial pump and motor operating principles
• Pump/motor rotating group composition and terminology
• Pump displacement control principles
• Hydrostatic balance of piston slippers and swash plate, and valve plate and cylinder
Color animations are used to explain:
• Closed circuits
• Operating principles of axial piston pumps and motors
• Hydrostatic balance of lubricated contacts
• Transmission charge circuit
• Cross-line (high pressure) relief circuit
5. Hydraulic Oil Cleanliness
This video deals with hydraulic fluid contamination and methods for its effective control.
Topics covered include:
• Various forms of contamination
• Sources of contamination
• Hard particle sizing and hydraulic component clearances
• How contamination causes degradation and catastrophic failures
• Measuring fluid cleanliness
• Filtration
• Color animations are used to explain:
• Three-body abrasion
• Particle capture in filters
• Operation and use of a filter cart
