Lubrication Tip
Using Field Data Collection to Enhance CMMS
Many times we find that the lubrication information in our computerized maintenance management systems (CMMS) is incomplete. It is a good idea to verify the data with a field data collection effort. It is useful to verify or identify the following:
• Equipment Name
• Equipment Number
• Type of Lubricant
(OEM recommendation)
• Correct amount
• Frequency for re-lubrication
• Oil Analysis candidate

Root Cause Analysis (RCA) Tip
Avoiding a disconnected Root Cause Analysis
When conducting Root Cause Analysis (RCA) be aware that after you have collected your preserve data you may have collected reports written by others who have investigated the same or similar failures in the past. You must treat the report as information that may provide some insight to possible hypotheses for your analysis. Hypotheses have to be verified as to whether or not it occurred and a report that was written in the past cannot be used in the analysis as a fact without re-verification. This RCA error trap can lead investigators to wrong conclusions in their completed analysis.

Change Management Tip
Eight elements are required for effective change in maintenance and reliability:
• Leadership – Direction and guidance for the organization
• Work Process – The method or process by which work is conducted
• Structure – The organizational framework supporting the process
• Group Learning – The ability of the organization to learn and adapt
• Technology – The software supporting the Reliability/Maintenance effort
• Communication – Dissemination of information
• Interrelationships – Effective and efficient working relationships
• Rewards – Reinforcement for performance (not always money)
Each of these elements are important for a successful change initiative on their own, but they are even more important when considered as a collective whole.

Predictive Maintenance Tip
Plant equipment should be assigned to the PdM Program according to the following priorities:
Priority 1 - Critical Equipment: Equipment which, when lost, causes the shutdown of the plant and Safety related items
Priority 2 - Failure prone equipment: Equipment that has a history of frequent failure (with significant operational or economic impact)
2A - Equipment with major impact
2B - Equipment with moderate impact
Priority 3 - Other equipment with significant operational or economic impact or long lead time parts
Priority 4 - All other equipment which would benefit from Predictive Maintenance
Priority 5 Equipment with little or no potential benefit from Predictive Maintenance

Vibration Analysis Tip
Phase analysis is a parameter often used for rotor balancing and as a Diagnostic Tool for detecting Alignment, Eccentricity, Bent Shaft, and Looseness faults in rotating machinery.
Additional techniques for phase analysis involve not just one static measurement, but a series of measurements aimed at detecting the change of phase in a vibrating system. The series of measurements is designed to detect the drift in the unbalance vector. Some sources of phase change might include slippage in felt driven paper rolls, slippage in sheaves and pulleys, trapped fluids in hollow rotors, or condensate buildup in paper machine dryer cans, cracked drive shafts, or loose rotor fits. Sometimes phase modulation may not be considered a “problem”, i.e., as in the monitoring of beat frequency induced by two or more rotating sources in close proximity.
As with other tools, extended use of phase analysis can draw the analyst a little closer to the root of the problem, or at least narrow the field of suspected faults.

Oil Analysis Tip
Lubricant Screening Process
The following is a sequential method of testing on-site new and used oil samples that have been collected for the purpose of evaluating lubricant and equipment health. This data must include sensory and inspection data along with all other relevant maintenance activities that can provide a clear evaluation of the lubricant, equipment and operating conditions.
Competent training and understanding of the on-site test equipment remains critical as in all diagnostic equipment. Calibrating or verifying calibration must be part of the lubricant testing program to ensure accuracy and repeatability of the tests. Test equipment and methods may be substituted to reflect the equipment presently in use in your facility as long as the test equipment is quantifiable and qualitative.
Basic Screening Tests
• OPERATIONAL CONDITIONS (Temperature / Pressure / Flow)
• APPEARANCE
• COLOR
• PARTICLE COUNT
• WATER CONTAMINATION (% Water Saturation and/or Crackle)
• VISCOSITY
• RULER (antioxidants and/or AN)
• FERROUS DENSITY / COUNT
• FERROGRAPHY
• DEBRIS ANALYSIS (Patch Test)

Root Cause Analysis (RCA) Tip
Avoiding a disconnected RCA
When conducting Root Cause Analysis investigators who cannot be there when the failed equipment is opened should have a strategy for data collection if the equipment fails again. The reason for this is because you may not be able to acquire all the data necessary for you strongest conclusions. This can happen when a RCA is not required at the time of the failure but at some later date it is decided that a RCA should be performed (Sometimes Political). It is difficult to perform an effective RCA when months have gone by since the failure occurred. The interviewees now have faded memories, parts have been thrown away, positional data is forgotten, and paper data is minimal. The strategy can be very effective if the equipment in question fails again.
