| Closely Monitor Copper Readings |
|
Copper readings can be alarming when increases are in the hundreds of parts per million. However, huge increases are typically insignificant in terms of component wear. Ironically, small increases in copper are a greater concern and should be examined closely. Copper alloy component wear generally is accompanied by lock-step increases in alloy metals such as lead, tin, aluminum and zinc. The amount of alloy metal present in brass/bronze components is only a small percentage of the total copper content. However, changes in these alloys should be taken seriously when present with copper increases. (Alan Johnson, The Halton Co.)

| Lubricant brand or type changes should always be viewed as machine and system disturbances. While change brings the potential for considerable opportunity, it also can introduce considerable risk. The opportunity is what you seek, and fortunately when it comes to a lubricant changeover, you have considerable control over the risk. Never forget the lessons of Murphy's law: "Anything that can go wrong will go wrong." |

GET THE ANSWER
From "Daily One-Minute Lubrication Inspections and Field Tests":
Just like conventional maintenance practices, autonomous maintenance is predicated on predictive maintenance and, in particular, routine inspections. These routine inspections are usually part of regular operator rounds that are performed each week, day or shift. But even those companies that are having success with operator-assisted maintenance sometimes miss the mark; and while their desires are well-intentioned, their execution of inspection routes is lacking. |
