Companies that implement the production process will always be faced with market competition. The process is done on the floor of the production required to produce a quality product and is able to win the competition. Machine condition greatly affects the results of the production process. A good machine will produce a quality product, otherwise the machine that his condition is not good will result in products that are not qualified. Companies engaged in the manufacture of the drug often have damage to the machine where the damage is mostly caused by engine component of a machine failure function so that the machine could not start the process when the operating damage to one of the machines at work, then the machine production process will be interrupted because it takes time to replace components of the machine. For that to be done, a step to improve the system of corrective maintenance which currently used the company so that the damage to the engine at the time of the working hours of the machine can be avoided. The purpose of this research is to get the engine maintenance schedule intervals by performing a critical component replacement tablet printing machine based on data obtained by the drug companies. Determining the schedule engine maintenance done by using Reliability Engineering. Of research results in retrieved that components are frequently damaged components namely Punch and Dies and the Pulley with the value of the respective machine reliability of 0.3429 and 0.4183. While the time Interval component replacement punch and dies the optimum is 791 hours per cycle of usage which means that the components of the punch and dies must be replaced at a time when the machine operates 791 hours. Whereas in the pulley component the optimum replacement time interval is 1695 hours per cycle of damage where the pulley component must be replaced when the engine is operating 1695 hours.
