Sampling Interval and Location of Sampling Valve

Usage:

IT14G 1WN


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 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. However, a sampling interval of 250 hours for all compartments is recommended.

Application

Studies have revealed, that in some high load applications and high temperature applications, 500 hours between oil samples is too long a time interval to predict potential failure modes. A 250 hour sampling interval provides more data points between oil change intervals thus increasing the odds for detecting a potential failure.

Determining Optimal Oil Change Intervals

Sampling compartments every 250 hours also provides oil condition/performance information to ascertain the optimal utility of a particular oil. Also, more data points enable close monitoring of component wear rates while obtaining maximum lubrication utility. For detailed information on extending oil change intervals, please contact your Caterpillar dealer.

Optimizing Component Life Cycle

An increased sampling frequency also provides better defined data trends from one oil change interval to the next. This enables close monitoring of component life cycle wear patterns to assure full component life cycle is realized.

In summary, the standard S·O·S oil sampling interval for all engines remains at 250 hours. While 500 hour oil sample intervals remain acceptable for non-engine compartments, they are not necessarily optimal. Under the above conditions, 250 hour oil sampling intervals are recommended.
