Course Description

This workshop covers mechanical drives operation, selection, installation, and maintenance. It provides the methods to properly install and maintain all major types of belts, roller chain, and coupling drives. Measurement and inspection techniques are also covered in detail. Basic bearing installation and maintenance is also covered with an emphasis on setting clearances for spherical roller bearings.
