We are not in a rush to propose expensive predictive technologies. There is little that can bolster a reliability program like a simple well-performed preventive maintenance program.
Basic lubrication, visual inspections and problems we can detect with our own senses provide a solid foundation. Performing those simple tasks with rigor tests our ability to put into practice our good intentions.
Don’t forget that visual inspections and simple measurements are predictive. If we can touch a sprocket and feel that the teeth are pointed, or measure a drive chain with a tape measure to determine chain stretch, we are performing predictive maintenance.
When we have demonstrated that we can perform these basics reliably, we can begin to layer on additional predictive technologies.
We propose two steps to stop running a primarily reactive maintenance program. 1) Switch as rapidly as possible from reactive to preventive maintenance (and simple predictive inspections). This will dramatically reduce the cost of failure. Then 2) gradually implement more predictive technologies. This will reduce the cost of maintenance.
