Machinery Lubrication 5 However, the origin of the impending failure (e.g., a particular bearing) and the root cause(s) typically remain uncertain to both the labora- tory analyst and the end user. Routine oil analysis for predictive maintenance is an effec- tive screen for abnormal conditions but ineffective at problem troubleshooting alone. Presently, oil analysis laboratories are barely more than data generators. The evaluators used by these labs have limited time to spend trouble - shooting and diagnosing individual samples with reportable conditions. Most evaluate several hundred data sets each day. They also rarely have a background in machinery lubrication, tribology, failure modes or machine design, and are gener - ally unfamiliar with machine operating conditions and the exposures these machines and their lubri- cants face. Be alert to the false promise or expectation that the laboratory can be your troubleshooter. Troubleshooting requires additional steps and persistent, timely action by the end user or desig - nated troubleshooter. Unlike a bad rash, these problems don't go away on their own. The offending condition must be identified, contained and surgically removed. The oil analysis report with the red alert only initiates the process. Be a pre-failure investigator and finish the process before the machine's service life finishes first. Critical machines that are in critical alarm need quick and effective troubleshooting by a qualified investigator. The following are exam- ples of common conditions often found on oil analysis reports that require unrelenting investi- gative analysis: • High/low viscosity • High wear metals • High particle count • Coolant leak • Fuel dilution • Varnish/sludge • Rapid oil aging • Cross-contamination • Sudden high acid number (AN) • Demulsibility issues • Air-handling issues • Dark oil issues • Hot running conditions Be a pre-failure investigator and finish the process before the machine's service life finishes first.
