Course Description

Covers basic hydraulic fundamentals used in Caterpillar products. Includes identifying the function of the various valves used in Caterpillar hydraulic systems, the function of vane pumps, gear pumps and piston pumps, and the function of ISO hydraulic symbols. Covers the process of disassembling and assembling hydraulic components, and tracing the oil flow and operation of various hydraulic systems used in Caterpillar products.

Intended Outcomes for the course

Upon completion of this course the students will be able to:

  • Explain and demonstrate basic hydraulic fundamental principles.
  • Explain and demonstrate the effects of flow through an orifice.
  • Explain the operation of the gear pump, vane pump, and the piston pump.
  • Disassemble, identify, and assemble the components of the gear pump, vane pump, and the piston pump.
  • Identify the components and explain the operation of the simple relief valve, the pilot operated relief valve, the flow control valve, the pressure reducing valve, the pressure differential valve, the check valve, the makeup valve, the sequence valve, and the directional control valve.
  • Identify the components and explain the operation of single acting cylinders and double acting cylinders.
  • Use the basic hydraulic training unit to build open and closed-center hydraulic systems.
  • Identify and explain ISO hydraulic symbols.
  • Trace oil flow through ISO hydraulic schematics
  • Trace oil flow and explain the operation of the pilot-operated implement system.
