How to Assign Preventive Maintenance Intervals with RCM

Hi everyone, I’m Nancy Regan, coming to you from Key Largo, Florida! In today’s video, I’m breaking down how to determine if a preventive maintenance task is the right action to take and how often it should be done, using the principles of Reliability Centered Maintenance (RCM).

I’ll walk you through a simple example—changing the engine oil in my 2014 Subaru Forester—and explain how preventive maintenance task intervals are assigned based on the Useful Life. You’ll learn how to assess the useful life of your assets and decide when to perform a scheduled replacement or a scheduled restoration task. I also demonstrate this using failure pattern B, showing you the conditional probability of failure.

Key Topics Covered:

• What makes a preventive maintenance task the right choice
• Understanding failure pattern B, the conditional probability of failure, and useful life in RCM
• How scheduled replacement and scheduled restoration tasks are determined
