This 32 hour, 4 day training program 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.
