An Introduction to Closed-Loop Oil Systems


Closed-loop (hydrostatic) hydraulic systems are used extensively in mobile and industrial machines. From the exterior, they appear complex and intimidating, and they certainly can be. This manual walks you through a hydrostatic transmission, step-by-step, explaining each and every component in detail. Illustrations and drawings are used throughout the manual to illustrate theory-of-operation and function.

This 100+ page manual is divided into four sections:

  • Theory-of-operation of the principle parts of a closed-loop oil system.
  • Where the principal parts of a closed-loop oil system are typically located and how they interact in the system.
  • A step-by-step guide on how the oil flows through the main circuit, charge circuit, and case drain circuit.
  • A comprehensive troubleshooting guide.
