April 17, 2008 Maintenance Tip
A well maintained backlog of maintenance work orders good. A backlog allows you to identify the types and numbers of craft skills required to complete the work and it allows you to take advantage of operating schedules and assists in the prioritization of work.

April 17, 2008 Optimization Tip
Beware 100% Hindsight
In almost all management and maintenance activities it is very tempting to rely on hard data; after all facts are hard to argue. There are two problems however with data. First, if often doesn’t show what you think it does. Second, it is all history, it tells us what was, not what could be. Sometimes relying on data can be like trying to drive the car with just the rear view mirror.
Make sure that you understand what the data truly represents, not what you think it represents.

April 17, 2008 How to Develop Proactive Key Performance Indicators
Join us for a 1 hour Web Workshop on April 25
The Association for Maintenance Professionals (a not-for-profit organization) is pleased to invite you to attend a free web workshop on How to Develop Proactive Key Performance Indicators (KPIs) by Ricky Smith, CMRP
Participants will:
* Gain common understanding of “KPIs” in Reliability and Maintainability
* Identify key maintenance and reliability metrics
* Learn the difference between leading and lagging indicators
* Take away your next steps to develop proactive KPIs
* Learn how companies are measuring reliability in their plants without a CMMS or EAM
April 17, 2008 Motor Testing Tip
Simple Effective Method to Determine if a motor has an open rotor.
In applications where more than one motor is common connected to a load, it can be difficult to determine if one of the motors has a rotor problem; especially in applications that use some type of load sharing algorithm. The easiest method I have found is to use a simple timing or strobe light. If the motor runs, while under load, as few as 5 RPM or more less than the nameplate RPM rating, then there is a high probability the rotor has open bars. This motors will exhibit other classic signs, such as heat and/or vibration, but can be difficult to isolate. We have even had outside Vibration Analysis tell us a bearing was going down in the motor that turned out to be good. This is because of the load sharing algorithm which can make the good motor load up to the point it is the one that SEEMS bad. Since I have developed this technique, every motor that I ruled had a bad motor was confirmed upon repair that it did have open bars, sometimes as few as two.

April 17, 2008 Maintenance Planning and Scheduling Tip
Base Future Planning and Scheduling Activities on Documented Asset Problems
Most PdM programs document the problem and create an issue report for Maintenance personnel to analyze and review. While these PdM methods have their benefits, there remains the aspect of follow-up and future Planning and Scheduling.
There are a few questions you should first ask:
1. What components and who is involved with your maintenance department’s feed back loop (communications channels)?
2. Do you know when and how problems have been corrected previously?
3. Was there an actual work request or work order created to repair the problem(s)?
4. What corrective actions were taken?
5. Were there alternative recommendations made and were those recommendations communicated throughout the maintenance department?
6. Was there an immediate need to repair the problem(s)?
7. Is the system where the problem(s) occurred of a critical nature to the operation of your process?
8. Do you know what the criticality of that system is in relation to your process?
By performing this initial and historical inquiry into identified issues, you may find that this approach is useful in sharing information, documenting issues, performing analysis and in obtaining necessary feed back. You should also establish a link with your EAM/CMMS system for the Planning and Scheduling of repairs. This EAM/CMMS link between PdM and Planning and Scheduling, will further provide results that will drive less redundant PM needs and reduce overtime callouts for emergency work.
