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 of the hydraulic oil as close as possible to the recommended sampling interval. The recommended sampling interval is every 250 service hours. In order to receive the full effect of 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.
- Before you obtain an S·O·S oil sample, operate the machine until the oil is warm and the oil is well circulated. Then obtain the S·O·S oil sample.
- Remove the protective cap from the sampling valve.

The sampling valve is located on the right side of the machine. | |
- Use a 8T-9190 Fluid Sampling Bottle in order to obtain a sample.
| NOTICE |

Do not use the same vacuum sampling pump for extracting oil samples that is used for extracting coolant samples. A small residue of either type sample may remain in the pump and may cause a false positive analysis for the sample being taken. Always use a designated pump for oil sampling and a designated pump for coolant sampling. Failure to do so may cause a false analysis which could lead to customer and dealer concerns. |
- Replace the protective cap.
Consult any Caterpillar Dealer for complete information and assistance about the S·O·S oil analysis program.
