| How Sludge Affects Oil Service Life |
|
| The presence of sludge in hydraulic oil can significantly reduce the service life of the oil. For example, with 1 percent sludge in an inhibited hydraulic oil, service life is reduced by nearly 40 percent.

| A grease's consistency is its ability to resist deformation by an applied force. The measure of consistency is called penetration, which is contingent on whether the consistency has been altered by handling or working. Learn the five categories of penetration along with how certain conditions will affect the consistency required for a grease. |

From "Machinery Failure Analysis and Troubleshooting":
An important step when investigating a gear failure is to analytically evaluate the theoretical capabilities of the gears. In some cases these data will help differentiate between types or degrees of failure. More frequently, however, these data will lead the investigator toward essential bits of evidence. For example, in a case where pitting is discovered relatively early in the life of a gear set, a decision must be made: Will the gears correct themselves and the pits heal over, or will the pitting continue into destructive pitting, causing gear failure? |
