Preventive Maintenance Program consists of actions that improve the condition of system elements for performance optimization and aversion of unintended system failure or collapse. It involves inspection, servicing, repairing or replacing physical components of machineries, plant and equipment by following the prescribed schedule. It is commonly agreed nowadays that preventive maintenance program can be very successful in improving equipment reliability while minimizing maintenance related costs. The availability of a complex system, such crimping process in production is strongly associated with its parts reliability and maintenance policy. That policy not only has influence on the parts' repair time but also on the parts' reliability affecting the system integrity, degradation and availability. This study was conducted based on the worst-case assessment for cycle run where during this cycle run 1.2mm diameter 316L solid stainless-steel rods; and it is the same material as the connector pin with 0.1mm thicker. This study provides an engineering test result on the evaluation of the Mean Time to Failure (MTTF) of the Connector Pin crimper determined at 17000 cycles.
