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.

5th EPRI Conference on International Maintenance - Hosted by PSE&G
August 8 - 10, 2005
Jersey City, NJ, USA
The electricity generation industry is continuing the rapid changes of the last five or more years from a stable, predictable past, to a future of competition, changing ownership, and dynamic new business goals. Adding to this new challenge, we are faced with the loss of long-term employees along with their knowledge. Many companies have mortgaged their human assets hoping to succeed in bridging the gap in knowledge and training without having developed a contingency plan.
The Electric Power Research Institute (EPRI) has structured this conference to provide some of the latest work being accomplished in the area of business evolutionary ideas, technology updates to forge ahead with more effective and efficient methods of completing maintenance work, as well as the ability to more accurately project what work has to be accomplished and when. This conference is structured for both the tactical maintenance needs as well as strategic ideas for focusing the future changes to be more successful.

Hydraulic Tip
Hydraulic System Preventive Maintenance Process that Works - “Maximize the Reliability of your Hydraulic System”
Preventive maintenance (PM) of a hydraulic system is basic and simple and, if followed properly, can eliminate most hydraulic component failure. PM is a discipline and must be followed as such in order to obtain results (A PM program should managed as a “controlled experiment”). We must view a PM program as performance oriented rather than activity oriented. Many organizations have good PM procedures, but do not require maintenance personnel to follow them or hold the personnel accountable for the proper execution of these procedures.
As in all PM programs, we must write procedures required for each PM task. These steps or procedures must be accurate and understandable by all maintenance personnel from entry level to master level.
PM procedures must be part of the PM job plan that includes tools or special equipment required to perform the task, parts or material required to perform the procedure with store room number, safety precautions for this procedure, and environmental concerns or potential hazards.
Preventive maintenance tasks for a hydraulic system could include the following:
– Change the return or pressure hydraulic filter
– Obtain a hydraulic fluid sample
– Filter hydraulic fluid
– Check hydraulic actuators
– Clean the inside of a hydraulic reservoir
– Clean the outside of a hydraulic reservoir
– Check and record hydraulic pressures
– Check and record pump flow
– Check hydraulic hoses, tubing, and fittings
– Check and record voltage reading to proportional or servo valves
– Check and record vacuum on the suction side of the pump
– Check and record amperage on the main pump motor
– Check machine cycle time and record.
Preventive maintenance is the core support that a hydraulic system must have in order to maximize component and life and reduce system failure. PM procedures that are written properly and followed properly will allow equipment to operate to its full potential and life cycle. The process allows a maintenance department to control a hydraulic system rather than the system controlling the maintenance department. We exercise control by deciding when we will perform maintenance and how much money we will spend.
The alternative is breakdown maintenance at a much higher cost.

Vibration Analysis Tip
Remember to adjust the window factor on your analyzer. Different window factors work better for different tests. For instance, if you’re going to conduct an impact test, switch to a uniform window. This offers good frequency certainty and is ideal for transient equipment.
