COUPLING AS 3813771 - Caterpillar

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 machine. Be prepared to collect the fluid with suitable containers before opening any compartment or disassembling any component containing fluids.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.
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.

The sampling valve for the hydraulic system is located on the base for the steering filter. Access the sampling valve from the right side of the machine.
Use a sampling gun in order to obtain the oil sample from the sampling valve. Do not take the oil sample from the drain stream, because 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.Consult any CLAAS Dealer for complete information and assistance about the S O S oil analysis program.
