Abstract
This chapter describes the prevention of machinery failures. The machinery failure classifications include: process condition changes; improper assembly/maintenance/installation: improper operating procedures; design deficiencies; and component wear out. Preventive maintenance requires that maintenance be performed at predetermined intervals. The most common preventive maintenance step is automotive oil change. The objective of this action is to remove the oil from the engine before oil contamination and deterioration cause excessive wear to the engine components. Predictive maintenance is based on component condition monitoring and trending. Reliability must be everyone's responsibility. The entire plant operations, maintenance, and engineering departments must be aware of the reliability program philosophy and must be able to implement it. Having operators and machinists equipped and trained in the use of simple vibration instruments, oil condition monitors, and laser temperature guns will significantly increase the reliability of general purpose equipment through the implementation of an effective predictive maintenance program.
