Obtain the Sample and the Analysis
In addition to a good preventive maintenance program, Caterpillar recommends using S·O·S oil analysis at regular scheduled intervals in order to monitor the condition of the hydraulic system and the maintenance requirements of the hydraulic system.
Each oil sample should be taken when the oil is warm and when the oil is well mixed. The sample should be taken at this time in order to ensure that the sample is representative of the oil in the transmission.
Obtain the S·O·S Sample
Use the oil sampling valve.
Caterpillar recommends using the sampling valve in order to obtain oil samples. The quality and the consistency of the samples is better when the sampling valve is used.
To avoid contamination of the oil samples, the tools and the supplies that are used for obtaining oil samples must be clean.
Refer to Special Publication, PEHP6001 for more information on obtaining a good oil sample. Consult your Caterpillar dealer for complete information and assistance in establishing an S·O·S program for your transmission.
- The oil sampling valve is located on the transmission oil filter behind the steps on the left side of the machine.
