Excessive program maintenance

MRs can also be used for trending purposes. Another excellent use of MRs is to help determine when PMs should be performed. Once you hit a threshold of hours, you can then initiate a PM. But to prove your current PM schedule is too frequent, you should start taking metering readings and tracking them in your CMMS system.

It may turn out that your AHU unit is running 15 hours per day, averaging hours of runtime per week versus the total hours that make up a week. Over time, these extra PMs would add up to wasted parts and labor costs. A manufacturing operation may need to schedule PMs based on accumulating production volume, i. A calendar-based schedule will not change as production volume changes over time, again risking too frequent or infrequent PMs. Rely on your equipment vendor or previous experience to determine the most accurate intervals to perform PMs.

Can you schedule too many PMs? Yes, you can. Still, too many PMs are probably better than not enough. CMMS and meter readings can help any organization implement a more intelligent, accurate and efficient PM schedule that strikes the right balance.

We all know that preventive maintenance is critical to supporting your assets — but can you do too much of it? Learn how to find the right balance! Written by Paul Lachance Ok, before I begin, I need to state: I am a big fan of preventive maintenance PM and am not advocating that maintenance operations teams stop doing them.

They may complain often of lack of equipment availability causing customer complaints or production issues. If you get this a lot, you should review Equipment Maintenance Calendars in your preventive maintenance scheduling software with the responsible people from the other departments.

For instance, you may find that rescheduling work or combining it may reduce many complaints. This is usually because maintenance costs seem to be high.

In addition, they may not understand the benefits of preventive maintenance. This can be handled by looking at the cost of equipment downtime. What happens if these equipment fail? If you have historical data from your CMMS software you can see how preventive maintenance has reduced the costs of unplanned or breakdown maintenance.

Being able to compare costs from prior periods will be helpful. After that, you can share this data and conclusions with management so they understand how good a job you are doing! This may have some justification. Firstly, review manufacturer recommendations. Secondly, look at your preventive maintenance plan. See if you can reduce some preventive maintenance or roll up some preventive maintenance jobs together. Review maintenance task instructions. See if they can be simplified.

Discuss with maintenance personnel to find why the believe some preventive maintenance may be unnecessary.
