Sampling Interval and Location of Sampling Valve

Usage:

Take the oil samples as close as possible to the standard intervals. In order to receive the full value from S·O·S oil analysis, you must establish a consistent trend of data. In order to establish a pertinent history of data, perform consistent scheduled oil samplings that are evenly spaced.

More Frequent S·O·S Sampling Improves Life Cycle Management

Traditionally, the suggested S·O·S sampling intervals have been at each oil change, 250 hours for engines, or every 500 hours for all other compartments. Under the following conditions, a sampling interval of 250 hours is recommended for all compartments.

Application

A 500 hour sampling interval may not give an advance notice of failures in some high load conditions and in some high temperature conditions. A 250 hour sampling interval provides more data between oil change intervals. This increases the chance for detecting a possible failure.

Determining Optimal Oil Change Intervals

Sampling compartments at every 250 hours provides information on oil performance in order to determine the best utility of a particular oil. Sampling more often can allow closer monitoring of component wear rates. For detailed information on extending oil change intervals, please see your Caterpillar dealer.

Optimizing The Component Life Cycle

A decreased sampling interval provides better trends of data. A decreased sampling interval enables close monitoring of wear patterns on components. This will ensure full component life.
