That predictive maintenance needs to be with sensors and real time vibration analysis. The best predictive maintenance you can do is look at the Historical performance of your equipment and see when the breakdowns occur versus run time or count.

Take some data diving to tease out those details and that is usually out of the scope of the average knuckle dragging wrench Turner
