Precision Maintenance: Belts, Chains, and Sprockets
Belts, chains, and sprockets. Chances are you have at least one if not all of these in your facility, and chances are you’re relying heavily on experience and judgment instead of quantitative inspection criteria. All too often the importance of proper inspection techniques and defined replacement criteria for these critical parts are overlooked. Don’t believe me? Just pull up some of your PM inspection procedure, discuss the topic at a tool box meeting, or observe someone performing the inspection. You might be surprised at the range of answers and opinions. If there isn’t a specific measurement or min/max criteria then you’re leaving the inspection up to chance. Another thing to consider is if these parts aren’t being installed properly in the first place you will undoubtedly see premature failures and reduced operational life, inspection criteria applies to installation practice requirements as well.
