TUBE AS 3029215 - 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 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, "Caterpillar Tools and Shop Products Guide" for tools and supplies suitable to collect and contain fluids on Caterpillar products.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 hydrostatic drive system and the maintenance requirements of the hydrostatic drive system.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 the hydrostatic drive system.Obtain the S O S Sample
At operating temperature, the hydraulic tank is hot and under pressure.Hot oil and components can cause personal injury. Do not allow hot oil or components to contact skin.Remove the filler cap only when the engine is stopped, and the filler cap is cool enough to touch with your bare hand. Remove the filler cap slowly in order to relieve pressure.
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.

Illustration 2 g00663369
Remove the filler cap from the oil tank for the hydrostatic drive system slowly in order to relieve any pressure.
Remove the filler strainer. Use a 1U-5718 Vacuum Pump or an equivalent pump. Insert the suction tube into the filler tube and draw a sample of the hydrostatic drive oil.
Replace the filler strainer and the filler cap.
Close both access doors. The recommended interval for oil samples is every 500 service hours. The oil samples should be obtained and recorded at that time. Refer to the Special Publication, SEBU6250, "Caterpillar Machine Fluids Recommendations", "S O S Oil Analysis".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.
