We are recommending oil analysis as a scheduled PM/PdM activity once a year on certain pumps and wondering when the lab gives us results saying that the oil needs to be changed out - would that be classified as corrective maintenance or preventive maintenance? I ask this because it will help us in decisions on managing our CMMS info.

ReliaGuy,
Do you have an entry code for CBM or PdM in your CMMS allready set up? My vote is Condition Based Maintenance if analysis suggests replacement of lube due to lube condition. If analysis reveals high partical count of metals then planned corrective for it's replacement/repair would be the norm here.

My thoughts would be the work order to take the sample would be a preventative maintenance. Any recommendations for maintenance based on the results would then be scheduled as a corrective maintenance due to the fact that you will be correcting an abnormality. The decision is a hard one because if you correct the oil then it is my understanding that you are also preventing it from deteriorating.

So long as you capture it the same way al the time it probably shouldn't matter.
Good luck

If the analyses dictates; then it's oorrective. If it's planned on specific intervals - it is a PM.
Guys, slightly different subject, for new project, Usually we preserved the equipment's (example centrifugal pump) with preservative oil during pump storage.I want to know why it is generally recommended to change the lube oil for centrifugal pump bearing before the commissioning?
I would say yes. Rarely have I see an OEM tell me what preservative oil they used and if that is the same as the recommended oil. I wouldn't want to use an oil that has sat in a machine during storage without knowing the details of the lubricant and it's condition. Too much opportunity for water or particulate contamination. Drain/flush and start fresh. Don't forget to baseline the new oil with your lab.
To the original question as to what the follow up work should be coded - I certainly believe that the initial oil sampling work order would be a PM or PdM (preventive or predictive) and the follow up for an oil change would be a CM (corrective) as the condition no longer warrants further use. We have created in our CMMS work order system a code called a CPM (corrective from a PM) which helps us understand how effective our PM work orders are in finding abnormal conditions.
Agree that the initial task to get the oil sampling would be considered part of a PM but the oil change based on the results would be a corrective measure. PM tasks are what would be applied to all similar assets in the portfolio and you would not change oil for all assets, only an oil analysis.
