Location: Las Vegas, NV - The Flamingo Hotel & Casino
When: Thursday, April 19 - Friday, April 20, 2007
Course Fee: $795/person, $530/person for groups of 3 or more
The 5 Pillars: Maintenance & Reliability Professional Review consists of 5 sections:
1) Business & Management
2) Manufacturing Process Reliability
3) Equipment Reliability
4) People Skills
5) Work Management
These sections correspond with the SMRP Body of Knowledge for the CMRP certification program. The course covers the concepts in each section in greater detail than the standards and includes real-world examples to illustrate the concepts.

March 22, 2007 Alignment Tip
What non-repeatability may be telling you.
Regardless of what type of alignment system or method you use, corrections should never be attempted if the readings don’t repeat within an allowable tolerance.
Here are some things to check for when this happens;
a) Make sure all components and bracketing are secure to the shaft, that nothing is rubbing, and that all equipment hold-down bolts are tight.
b) If possible, increase the measuring average of the laser to compensate for ambient vibration. Dial indicator users cannot compensate for this effect.
c) Tooling used to turn large machinery may be deflecting the shaft and influencing readings; use the Multipoint method of taking readings if your laser system offers this.
d) Wait for recently run machines to cool off to ambient temperature and all thermal gradients within the machines to stabilize before taking readings.
e) After eliminating all of the above, you may very well still have machinery issues such as bad or excessively worn bearings.

Now in the 11th year of presenting an annual conference in the vital area of maintenance and reliability, the University of Tennessee Maintenance and Reliability Center together with Reliabilityweb.com is again providing an opportunity to interact with attendees from both industry and academia; from both the private and the public sectors; from organizations just starting in maintenance and reliability to those well along in their journey.
March 22, 2007 Condition Monitoring Tip
Many vibration analysis programs do a great job of coming on-line with large sections of a manufacturing facility included in vibration routes, but few facilities find the time to fine tune these programs once they are implemented.
You should perform audits on your vibration analysis program at least yearly to determine if it is finding legitimate defects or problems in the facility.
These audits should include:
- manpower usage
- machine / measurement point collection figures
- repaired / re-qualified machine counts
- and statistical analysis of “Critical” and “Common” machine types.
By using the data collected during your audit, a simple road map should evolve on how you can better utilize the resources you have at your disposal.
Additionally, any machines that are “bad actors” will stand out during the audit, placing them as a top priority for FMEA or RCFA studies.

March 22, 2007 Motor Management KPI Tech Tip
In order for any motor management program to be effective, you MUST have a healthy electrical maintenance program. There are a minimum of seven parts to a successful electrical maintenance program including:
1) Drawings and Documentation Control
2) Maintenance Tasks related to Electrical Maintenance
3) Arc Flash and PPE
4) Load and Power Quality Monitoring
5) Root-Cause-Analysis Process
6) Electrical Work Procedures Tied to Safety
7) An Emergency Work Plan for Reactive Faults
These areas must have a combined score over 85% before starting your motor management strategy.
March 22, 2007 Mikron Infrared’s M7800 Camera with DualVision
Mikron’s economical, easy-to-use, high-performance infrared PPM camera, with laser pointer and digital visual recording is now available with DualVision—a visual and thermal image functionality option.
What is DualVision? DualVision is the ability to display a visual image with thermal overlay, on the M7800’s large 3.5” LCD. The opacity of the overlayed thermal image can be adjusted from 0-100%, allowing the operator to pin-point problems faster! Both visual and thermal images are downloaded via USB 2.0.
The M7800 features a 320x240 resolution, and three additional optional lenses. It is compatible with the economical Mikron SpyGlass™ Lens and ViewPort safe electrical cabinet inspection combination.

March 22, 2007 Vibration Analysis Tip
How sure are you about your unbalance diagnosis?
Diagnosing unbalance with vibration spectra may seem like a simple matter; just look for a high peak at the running speed (1X). However there are a number of other conditions that also generate high 1X peaks.
One way to separate fault conditions such as unbalance, misalignment, bent shaft and cocked bearing is by using phase readings. If you have a single channel data collector, and you do not have an easy way to get a phase reference (e.g. once-per-rev tachometer), then a phase reading may be difficult to collect. However if you have a two-channel data collector, or you have a strobe, it is not difficult to collect phase readings, and it is highly recommended that you take a few quick readings in order to be sure about your diagnosis.
The key rule is that the difference in phase between a vertical reading and horizontal reading should be approximately 90 degrees (give or take 30 degrees). If you repeat the test at both ends of the machine, the difference should be similar at each end.
Depending upon the nature of the unbalance, the difference in phase between two vertical readings taken at each end of the machine should be between 0 degrees (if it is pure static unbalance) and 180 degrees (pure couple).

March 22, 2007 Ultrasonic Motor Greasing Tip
Don’t Touch My Motor, Here .. or Here !
When using an audible or ultrasonic grease gun attachment for lubricating motors. Be sure that the motor grease fitting tube and grease gun coupler do not touch the rear fan bell section of the motor or the coupling guard at the front of the motor.
If there is any touching in these areas (even just the paint), the bearing noise is not likely to be the dominant sound that you hear or register on the meter.
Sometimes in order to get a true reading you may have to snap the coupler to the zerk and pull it away from the contact zone while greasing. A pistol grip grease gun will make this easier.
