Generating Failure Codes for CMMS Implementation by Bill Keeter
CMMS-2005 Learning Zone Session
Computerized Maintenance Management Summit
July 26-29, 2005
Indianapolis Indiana
One of the most important parts of CMMS implementation is the generation of failure codes for the craftsmen to record. Picking good codes means that you will have information that is useful for continuous improvement activities. Picking inadequate codes means that crafts people will soon grow tired of carefully entering codes that are not perceived to generate value for the organization.
In this session Bill will show you how to use Failure Modes and Effects Analysis to generate useful codes that will provide a path forward for continuous improvement. You will see how good codes can help you generate useful failure statistics so that you can forecast future failures and develop preventive/predictive activities that will minimize the business impact of failures.
Join Bill plus more than 35 other presenters, workshop leaders and learning labs directors at CMMS-2005.

Belt Tip
Belt Tip dated 04/07/05 was state below:
When removing belts from multiple belt pulleys, mark with chalk or crayon the order and the direction to the motor or drive they are coming off. 1,2,3,4,5,6 with an in or out arrow.
After all, that is why you bought a matched set. Putting them back on helter skelter any where will lead to vibration and possible bearing failure down the road.
My suggestion:
Since belts are no longer sold in matched sets, when replacing belts in multiple groove pulleys they should be vulcanized together under one backing, such as the Gates Powerband belts.
When removing Powerband belts mark the direction of rotation to the motor or drive they are coming off of with chalk or crayon and install it in the same orientation.

Airborne Ultrasound Tip
Vacuum or In-Leakage Detection
Vacuum (in-leakage) leaks are internal and sometimes these leaks can be found using isopropyl alcohol, de-mineralized water or a liquid agent your system can accept and applying it to the piping surface or suspect area while using an ultrasonic contact probe touching the suspect area. The sound will be that of bubbles popping or a “Rice-Krispies” sound. This application is great on autoclaves, sterilizers, condensers, etc…

Alignment Tip
Laser System Lens Cleaning
Always use an optical quality micro-fiber lens cleaning cloth to avoid scratching the polarized coatings of your sensor lens. These are also ideally suited at sucking fingerprints and dust right off the lens surface.
Avoid using lint-laden cotton cloths or tissues.

Spare Parts Storage – Proper Storage Locations
While a previous maintenance tips dealt with identifying storage locations, this tip will focus on the right type of location. Many companies fail to give the storage condition of spare parts the proper consideration. When they are ready to use the spare parts, they find that they are either defective or have been sufficiently damaged in storage and they will no longer deliver their full service life. Comfier one common example: rolling element bearings. While, many companies rely on supplier arrangements to eliminate storing bearings, they will still find bearings stored in the storeroom in major spares such as pumps, gear cases and motors.
• When examining the storage conditions for bearings, what is found in the storeroom?
• Are the locations, clean and humidity controlled?
• Are the bearings still sealed in the original containers?
• Are the bearings located in an area that is free from external sources of contamination and vibration?
In many cases, the bearings have been opened and checked by someone who was not sure of the OEM number and wanted to physically compare the bearings. In this case, unless the bearings are re-packaged, they are being damaged. The exposure to atmospheric conditions, acid in the skin of the technician, and other conditions will quickly deteriorate the life of a bearing. Even if the bearings are stored as part of a component in a spare part assembly, they will incur damaged if the storage conditions are not monitored. For example, if the bears are stored, mounted under load and not rotated, external vibration may cause a problem with false brinnelling.
Other power transmission components, such as v-belts, roller chain and gears also must be stored under proper conditions to insure their full service life when installed.
It is only when spare parts are stored in easy to find locations, where they are properly stored and protected that they will deliver their design life expectancy, keeping maintenance spare parts cost at a minimum level.
