Crusher is one of the machinery in salt industry with the highest failure frequency. In this study, six components reliability are investigated: Bearing, Electric motor, Pulley, Roll, Adjuster, and V-Belt. From its reliability analysis, four preventive maintenance (PM) plans are created, namely Component reliability-oriented PM, Component lifetime-oriented, PM based in 2016 MTBF, and PM based on 2015 optimum MTBF. Afterward, the four PM plans compared in terms its reliability, cost, and production. The result are the lifetime-oriented PM has the best production, the PM based 2016 MTBF has the best cost, and the PM based on 2015 optimum MTBF has the best reliability. Reliability-oriented PM is the second best in terms of reliability and cost and therefore it is recommended to be applied. © 2019 Int. J. Mech. Eng. Rob. Res.
