We’re told machines should not be allowed to swallow air. But what if they do?
What harm could be caused by this bubbly stuff anyway? Do we really have to make the machine burp? Will a few pats on the back do the trick?
For many of you, air contamination is no laughing matter. Why? Because air contamination is a serious condition.
Why is there such a big emphasis on oil cleanliness? The question has been asked numerous times over the years by maintenance technicians and managers alike.
The bearing overlay can play a critical role in determining bearing life. The authors analyzed two different mechanisms of overlay removal from production engines operating in major fleets. The first involves the loss of tin in the overlay and the second was due to a small coolant leak. Both were returned at low mileage.
When your bearings aren’t lubricated properly, friction can cause damage and threaten processes. However, ultrasound equipment can read the decibel levels of over- and under-lubricated bearings and indicate to the maintenance technician if adjustments are in order. When dB levels are consistent, that tells the technician that lubrication is where it should be.
“Does water ingression damage a synthetic lubricant? I thought one of the main benefits of synthetics was their water-repellent properties.”
