November 03, 2005 Lubrication Selection Strategies & Guide for Improving Enclosed Gearbox Reliability
LubricationWorld - Co-located with
The 20th International Maintenance Conference
December 6-9
Tampa Florida
Short Course led by by Lawrence Ludwig, CLS, OMA, CMFS, Schaeffer Mfg.
Gear lubricants must often perform in the presence of large quantities of water, high operating and ambient temperatures or in highly contaminated environments, while still maintaining their ability to protect the enclosed gear drives from wear, especially during high load conditions. OEM design changes have downsized gearboxes, yet they are operating has higher speeds and loads - this results in higher operating temperatures and increased gear and bearing distress. In this short course you will learn about the different types of enclosed gear lubricants, some of the important properties an industrial gear lubricant must possess, and the proper selection of an industrial gear lubricant for an application.
Attend this subject plus 50+ other short courses and learning zone sessions at LubricationWorld.

November 03, 2005 Reliability Centered Maintenance (RCM) Tip
Implementation Equals Success in RCM
As I instruct managers and facilitators around the world I like to inform them that in the world of RCM, Implementation is the graveyard of most failed efforts. The best way to ensure your company has a successful RCM effort is to implement the tasks that came out of your RCM analysis. Implementation requires structure and discipline. I offer the following tips assist in implementing your RCM analyses:
• Decide prior to starting your analysis, who will be responsible for tracking the progress of task implementation.
• Set aggressive but realistic goals for completing the RCM tasks.
• Assign each task to a specific individual instead of a group or supervisor.
• Don’t schedule start another RCM in that specific area until at least 80% of the tasks identified
It should be no surprise that the companies who have successful RCM programs are also the same companies that implement the results from their analyses.

November 03, 2005 IR Camera Winner
Mikron recently announced the winner of the “Name that Camera” contest that we ran several months ago.
Omaha Thermographer Wins $20,000+ prize in Mikron Infrared’s Name the Camera Contest
TrueShot™ Name Wins Infrared Camera and Training Valued at more than $20,000
Bryan Dring, president of ThermaScan Solutions in Omaha, NE, is the happy winner of Mikron Infrared’s “Name the Camera” contest, which netted him a new Mikron M7800 thermal imaging camera and Snell Infrared training package with a total value of $20,490. The contest was sponsored by Mikron and Snell to find a memorable name for Mikron’s new line of M7800 high-performance thermal imaging cameras, introduced to the market last summer.

November 03, 2005 Data Analysis Tip
Data Analysis Tip Part 3 – Compare Identical Machines
Archived at
http://maintenancetalk.com/blog.php/tipsblog
When troubleshooting or using vibration in a Predictive Maintenance program comparing identical machines to each other is often the best method to diagnose a problem – especially if you suspect a problem exists in one or more of the machines. When vibration data is collected on a bearing housing using an accelerometer, one is not only measuring vibration forces, but also the effect of the structure on these forces. There is no vibration severity guide in existence that accommodates for the effect of the structure and this is one reason why guides are only “guides”. Not only that, the effect of the structure is different at every frequency.
Some small machines normally exhibit high vibration levels while some large machines barely vibrate at all. In either case, they all produce unique patterns. The best comparison one can make therefore is between two identical machines, or between reference data from the same machine from an earlier test date. Always test the machines in the same locations and under the same conditions. (speed, load and configuration). “Normalize” the data and compare them. If troubleshooting, note the test conditions and save the data for later use.

November 03, 2005 Motor Testing Tip
The Importance of Backing Up Data
The importance of backing up data cannot be overstated. After figuring out how to test motors, setting up a predictive maintenance program and spending a lot of staff hours to test the motors only to lose the data is detrimental to business. Data lose will not only cost time, but it will also cost information and the history of each motor. Spending a few minutes at frequent intervals backing up data will be time well spent. Data collected carefully and meaningfully gives a picture of the history of each motor and is an asset in determining the health of the motor. SO BACK IT UP!!!!

November 03, 2005 Accelerometer Installation Tip: Avoiding Ground Loops
In order to provide proper shielding and prevent ground loops, shield and common grounding should be carefully considered. Ground loops are developed when a common line (i.e. signal return/shield) is grounded at two points of differing electrical potential.
For sensors with coaxial cable, the center conductor carries the signal and power, while the outer braiding provides the shielding and signal return. Normally the cable shield is electrically isolated from the sensor housing. This isolates the shield from the mounting point of the machine and prevents ground loops. If a non-isolated sensor is used, it is recommended that an isolated mounting pad be used to break up possible ground loops.
For sensors using two conductor/shielded cable, the signal and power are carried on one lead and the signal common on the other. The cable shield serves to protect the signal from ESD and electromagnetic interference. The shield should be grounded at only one point, normally to the readout equipment.
NOTE: In all cases, it is very important that the cable shield terminations be properly grounded. Failure to do so in high EMI/ESD environments can result in damage to the sensor electronics.
November 03, 2005 Root Cause Analysis (RCA) Tips
RCA DEFINITION
One of the many problems with the use of the term RCA is that it has no standard, accepted definition. Even the major RCA providers on the market today cannot agree on a definition of RCA nor its essential elements. This is primarily because it is blocked by business concerns that if such definitions and elements are standardized, and my product or approach does not meet the requirements, I will be at a business loss {that is another article!).
My point here is that for proper communication within your own organization, you should develop a definition of what RCA is for your purposes. That way everyone can be on the same song sheet when it comes to RCA. Without such a definition, everyone interprets it to be what they want it to be and there is a breakdown in communication.
Below is a definition provided on a listserve I participate on, that we find acceptable:
Root Cause Analysis is any evidence-driven process that, at a minimum, uncovers underlying truths about past adverse events, thereby exposing opportunities for making lasting improvements. (5/20/04 – Mr. William Salot)
Use this as a draft to form your own definition, but whatever you do, define what RCA is for your organization.
