Addendum to Course Description
Required course for Apprentices registered in the Millwright/Industrial Maintenance Technician Apprenticeship Program. It is open to any other student but requires Department Permission to take this course.
Intended Outcomes for the course
- Perform preventive and corrective maintenance for industrial equipment and facilities using manufacturers' specifications and equipment history applied to the installation and replacement of bearings and seals.
- Perform preventive and corrective maintenance for industrial equipment and facilities using lubricant manufacturers' specifications and equipment history applied to the lubrication of moving parts. Meet industry standards for correct lubrication.
- Use tracking software to log preventive and corrective maintenance of industrial equipment and facilities and analyze tracking logs to plan future maintenance.
- *Define lubrication processes with trade-specific industrial materials and equipment (*required statewide outcome).
- *Apply OSHA practices in relationship to the specific trade (*required statewide outcome).
Course Activities and Design
Course design is mostly lecture coupled with demonstration of a variety of the bearings, seals, and lubricants used at today's Industrial work sites for both equipment and the facility. Guest experts include manufactures' representatives from both equipment companies and lubricant companies.
- Introduction to several tracking software programs for logging preventative maintenance
- Introduction to the host of different bearings and seals available to the Millwright/ Industrial Technician using both Power Point and online presentations.
- Lubricant analysis
Outcome Assessment Strategies
Assessment will be accomplished using skills' checklists filled out by an adequate sampling of Millwright/Industrial Maintenance Technician Training Agents and/or an Apprentices' Journey Person.
