| Smoothing Out Bulk Grease |
|
After scooping out grease from a bulk grease container, make sure the top surface of the remaining grease in the container is level. Don't leave the grease surface with pockets or cavities. This will cause bleeding of the base oil from the grease thickener into these zones. In order to use the grease in such case, the separated oil would need to be worked back by agitation. This should only be attempted if there is no risk of dirt entering the bulk grease during agitation. (C. Muralidharan, Mak Controls and Systems)

| Today's increasing complexity combined with an overwhelming amount of work and a severely limited amount of time often mean the only way to survive is by addressing the biggest problems to their shallowest depth. This is a frustrating, futile and sometimes deadly position in which to be. Maintenance professionals of the 21st century not only must be competent problem-solvers, but they also must be able to wrestle with complexity and win. Checklists can be a big help in this regard. |

GET THE ANSWER
From "Machinery Failure Analysis and Troubleshooting":
There are many ways bearings can be damaged before and during mounting and in service. The pattern or load zone produced on the internal surfaces of the bearing by the action of the applied load and by the rolling elements is a clue to the cause of failure. To benefit from a study of load zones, one must be able to differentiate between normal and abnormal patterns. |

Imagine that you have just been hired as the reliability engineer for a manufacturing plant. The plant has more than 4,000 pieces of rotating equipment. How would you go about selecting which components require routine oil analysis, and how would you select the correct series of oil analysis tests for these systems?
