Maintenance Tip
Are your V-Belts hanging on hooks in your parts room indefinitely before use? Over time, these belts will become warped and crack at the hang point. The implication for reliability is that upon installation, you have just introduced a defective part into your equipment and increased the likelihood of premature failure. To avoid this potential issue try storing your V-Belts on shelves.

Social Network Value for Maintenance and Reliability
This year I have become a regular user of LinkedIn’s discussion groups. There are many quality and credible maintenance and reliability groups with great dialogue. Questions are posted by those looking for answers, and a whole discussion follows. I recently responded to a query about MTBF and wanted to share my response with you.
Group Question/Query:
“I’m looking for info regarding calculation for MTBF (Mean Time Between Failure) for seasonal assets. Any help is appreciated.“
|
Greg Folts’ Response:
Like all measures, you should start with your goal of why you are measuring. If your target is improvement, the "time" you would most likely be interested in is the operational time during the heavy running season. If over a 3-month harvest a tractor was used 8 hours per day, I would be concerned with the time between failure during the harvest. Anything you do to increase the time between failure would likely benefit your output. You might want to look over weekly or monthly periods to see the time between failures. If the tractor sat idle for the other 9 months, factoring these time periods, while technically correct, would not give you the data to drive improvement.
If your goal, on the other hand was just to make the numbers look good...
It is also good to remember that MTBF when used with MTTR (Mean Time To Repair) represents true improvement. One failure in 30 days, for a 2 week duration, would look the same as 1 failure for 3 minutes, if only looking at MTBF.
I encourage maintenance & reliability professionals interested in quality feedback and interaction with peers to create a LinkedIn account, join some relevant groups and begin to ask questions, share knowledge and interact with your peers.
