Reliabilityweb.com created PdM-2005 to focus on:
• Vibration Analysis
• Airborne Ultrasound
• Infrared Imaging
• Motor Testing
• Oil and Wear Particle Analysis
• Other condition monitoring technologies
When: September 19-22, 2005
Where: Atlanta Georgia
Format: 6 Full day workshops, 12 90 minute short courses and over 30 learning zone presentation sessions in a friendly business casual environment.

July 27, 2005 Maintenance Metrics Tip
Crew Level Metrics
One of the interesting points I have found in maintenance is that “we don’t know what we don’t know”. If only we could identify the things that are killing equipment reliability. The best way to begin to focus in on the real problems, and not the ones that just showed up, is to train your crew in metrics that impact reliability. Begin with one metric and post it on your bulletin board and track it (and update your graph, yes graph) daily but talk about it as a crew weekly. Remember you must have enough data points in order to know if something is a trend or something that just happened (or maybe twice but it is probably not the real problem).
Some metrics I like to track at the crew level are:
• MTBF “Mean Time Between Failure” (by area of responsibility)
• MTBF (by asset)
• PM Labor Hours vs Emergency Labor Hours (total)
• PM Labor Hours vs Emergency Labor Hours (by asset or area of the plant)
• Parts Cost by Asset
• Capacity (by shift and by day)
• Maintenance Cost by Unit (by day and by month)
These metrics are a good start. REMEMBER START WITH ONE METRIC AND BUILD FROM THERE.

July 27, 2005 Fundamentals of RCM Analysis Training
Aug 16-18 - San Diego CA
Sept 7-9 - Jacksonville FL
A practical course designed to provide an introduction to the RCM process and introduce the skills necessary to perform RCM analysis. The class is intended for anyone interested in performing RCM analysis or responsible for implementing an RCM program, including equipment maintainers and operators, maintenance planners and managers, and engineers. The course is based on an SAE JA-1011-compliant RCM process and provides practical knowledge and case studies that can be incorporated into any RCM process.

July 27, 2005 Motor Testing Tip
Low Load and High Current Imbalance
An unloaded motor can create a 10-15% current imbalance yet be perfectly healthy. This is a normal design response caused by unbalanced flux in the core iron between phases at low loads. When performing power or current analysis on three-phase induction motors, verify the percent loading at which the motor is operating. If possible, increase the load on the motor to determine the validity of a high current imbalance. A normal current imbalance for healthy motors operating at or near design load is 3% or less.

July 27, 2005 Maintenance Tip
Different coupling manufactures us use different names for the gap between coupling hub faces. One may call it “hub separation”, another “clearance between hub faces”, another a “gap between flanges”. Regardless of what it called it is the axial dimension or distance.

July 27, 2005 Vibration Analysis Tip
Obtaining reliable speed info from the machinery nameplate is made difficult (often due to the lack of nameplate) as time goes on.
In the interest of supporting your reliability department (or reducing the time that your outsourced engineer spends onsite) a small spreadsheet should be compiled where all known machinery details can be retained for future reference.
All sites may not a CMMS system, but for those sites that do, this information should be retained against those assets listed.
Speeds, bearings, frame sizes, power, model and serial numbers are all immediately beneficial details to the generation of a condition monitoring program.

July 27, 2005 Airborne Ultrasound Tip
Valve Leak Detection
Airborne ultrasound is a great tool for listening to valves for leakage. Say your valve is closed but, you suspect it is leaking on the closure side. You can set-up a four point check of the valve to listen for leakage. Point (A) is upstream of the valve, Point (B) is at the valve inlet side, Point (C) is at the valve outlet side and Point (D) is downstream of the valve. Point A & B are typically the same value or close, Point C will always be louder than point D if the valve is leaking past its seats. If point D is ever louder than C, there is a problem downstream causing D to be louder. You may also want to take the contact probe and move around the valve to pinpoint were the leak is. Remember the closer to the source (short wave signal) the louder or more intense the leak will be.

July 21, 2005 Infrared 101 - Getting Started with Infrared Thermography
Pre-Conference Workshop by John Snell
Predictive Maintenance Technology Conference & Expo
September 19-22, 2005
Atlanta, Georgia
Reliability managers and technicians should attend this one day course to learn more about infrared thermography. Whether you already own equipment, are “shopping around,” deciding to add the technology or just want to find out more, spending a day to learn about infrared will pay large returns. Some of the topics John Snell will discuss include:
· Why companies are using thermography
· What thermography will not do
· What equipment, new and old, can be used
· Basic theory behind using the technology
· What are the primary applications and how do they work
· Safety issues
· Setting up a successful program
· Personnel certification
Snell Infrared is independent of equipment sales ensuring you will get an honest, informed presentation with straight facts and no fluff. Time for questions and answers will also be available.
Attendees will leave with information that will enable them to decide whether or not this is a technology they should pursue. In addition, those who participate will develop a solid foundation for selecting equipment, a clear understanding of what the technology can and cannot accomplish and an outline of a path to success.
The workbook for this course consists of the presentation slides (in color) and several useful background articles.

July 21, 2005 Maintenance Tip
When an Allen Head screw seems to have the head stripped out, it is almost impossible to remove. Use a new standard Allen wrench, lightly tap the wrench into the head with a hammer. This will seat the wrench in the undamaged portion of the socket head for easy removal.
