MODULE DETAILS

Module 6: Hydraulics

 

Nominal duration: 4 weeks (48 hours total time commitment)

 

This time commitment includes the preparation reading, attendance at each webinar (1 hour plus 15-30 minutes for discussion), the time necessary to complete the assignments, and further study.

 

MODULE PURPOSE

 

 

This module helps students to increase their knowledge of the fundamentals, to improve their maintenance programs, and become excellent troubleshooters of problems in this area. Understanding ‘how’ a hydraulic component works leads to an understanding of how and why it fails. Towards the end of the module, students will have developed the skills and ability to recognize and solve hydraulic problems in a structured and confident manner.
