This lesson explains the concepts of lubrication, friction, and viscosity and demonstrates the benefits of a proper lubrication program. Additionally, the properties of common solid, semi-solid, and liquid lubricants are described as well as the benefits associated with synthetic lubricants and the functions of additives and inhibitors. Common types and causes of lubricant contamination are described and proper methods of lubricant storage are demonstrated.

This lesson explains and demonstrates how various types of lubrication systems operate, including ring, bath, splash, constant level and forced feed lubrication systems. Participants learn pertinent maintenance checks to make for each type of system. Manual devices used to apply lubricant are covered as well as the purpose of filters and the importance of filter maintenance in lubrication systems. Additionally, the lesson indicates the benefits of oil sampling and analysis and identifies several factors that can cause lubrication failure.
