Care must be taken to ensure that fluids are contained during performance of inspection, maintenance, testing, adjusting and repair of the machine. Be prepared to collect the fluid with suitable containers before opening any compartment or disassembling any component containing fluids. Refer to Special Publication, NENG2500, "Caterpillar Tools and Shop Products Guide", for tools and supplies suitable to collect and contain fluids in Caterpillar machines. Dispose of all fluids according to local regulations and mandates. |
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 transmission and the maintenance requirements of the transmission.
Each oil sample should be taken when the oil is warm and when the oil is well mixed in order to ensure that the sample is representative of the oil in transmission.
The recommended oil change interval is every 1000 hours. The recommended interval for samples is every 250 hours. The oil type is TDTO. See the Operation and Maintenance Manual, " S·O·S Oil Analysis".

The sampling valve for the transmission oil is located at the rear of the machine. | |
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 machine.
