Illustration 1 g00755426
The oil sample for the engine oil is obtained through the crankcase drain valve.
Illustration 2 g00755418
The hydraulic oil sampling valve is located next to the propel pump.
Illustration 3 g00755432
The oil sample for the final drive planetary is obtained when the planetary oil is changed through the drain plug. Use the procedure for changing the oil for the final drive to drain and refill the final drive planetary.
Illustration 4 g00755433
The oil sample for the differential is obtained when the differential oil is drained through the drain plug. Use the procedure for changing the oil for the differential to drain and refill the differential.
Illustration 5 g00761614
The oil sample for the propel transmission is obtained when the oil for the propel transmission is drained through the drain plug. Use the procedure for changing the oil for the propel transmission to drain and refill the propel transmission.
Illustration 6 g00755436
The oil sampling valve for the rotor transmission is located on the oil cooler for the rotor.
Illustration 7 g00755435
The oil sampling valve for the rotor drive differential is located on the oil cooler for the rotor.Consult your Caterpillar dealer for complete information and assistance in establishing an S O S program for your equipment.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. A sampling interval of 250 hours is recommended for all compartments.Application
A 500 hour sampling interval does not give advanced 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 potential failure.Determining Superior 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 Component Life
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.
