Hot oil and components can cause personal injury.Do not allow hot oil or components to contact skin.
Care must be taken to ensure that fluids are contained during performance of inspection, maintenance, testing, adjusting, and repair of the product. Be prepared to collect the fluid with suitable containers before opening any compartment or disassembling any component containing fluids.Refer to Special Publication, NENG2500, "Dealer Service Tool Catalog" for tools and supplies suitable to collect and contain fluids on Cat products.Dispose of all fluids according to local regulations and mandates.
Obtain the sample of final drive oil as close as possible to the recommended sampling interval. The recommended sampling interval is every 500 service hours. In order to receive the full effect of S O S oil analysis, establish a consistent trend of data. In order to establish a pertinent history of data, perform consistent oil samplings that are evenly spaced.Each oil sample should be taken when the oil is warm. Also, the oil is mixed well to ensure that the sample is representative of the oil in the final drives.If the machine is operated under a high load and/or under high temperature conditions, sample all fluids at the 250 hour interval.
Position one final drive so that the oil level mark is horizontal and the drain plug is at the bottom.

Remove the oil filler plug.
Use a 1U-7683 Suction Gun or use an equivalent pump that is inserted into the filler plug hole in order to obtain an S O S oil sample. Install the oil filler plug. Note: Do not use the drain stream method to obtain a sample of the final drive oil. A stream of dirty oil from the bottom of the compartment will contaminate the sample. Likewise, never dip an oil sample from an oil container or pour a sample from a used filter.
Repeat the procedure on the other final drive. Note: Do not combine the oil samples for the final drives. The oil samples must be kept separate in order to perform an analysis for each final drive.To avoid contamination of the oil samples, the tools and the supplies that are used for obtaining oil samples must be clean.Reference: Refer to, "Lubricant Viscosities" in the Maintenance Section of this manual for the correct fluid for your machine.Reference: Refer to Special Publication, SEBU6250, "Caterpillar Machine Fluids Recommendations", "S O S Oil Analysis" for information that pertains to obtaining a sample of the final drive oil. Refer to Special Publication, PEHP6001, "How To Take A Good Oil Sample" for more information about obtaining a sample of the final drive oil. Consult your Cat dealer for complete information and assistance in establishing an S O S program for your machine.
