HYDO Advanced 10
Cat HYDO Advanced 10 is the preferred oil for use in most Caterpillar machine hydraulic and hydrostatic transmission systems when ambient temperature is between −20 °C (−4 °F) and 40 °C (104 °F). Cat HYDO Advanced 10 has an SAE viscosity grade of 10W. Cat HYDO Advanced 10 has a 50% increase in the standard oil drain interval (up to 3000 hours) for machine hydraulic systems over second and third choice oils when you follow the maintenance interval schedule for oil filter changes and for oil sampling that is stated in the Operation and Maintenance Manual. 6000 hour oil drain intervals are possible when using S O S Services oil analysis. When you switch to Cat HYDO Advanced 10, cross contamination with the previous oil should be kept to less than 10%. Consult your Cat dealer for details about the benefits from the improved performance designed into Cat HYDO Advanced 10.Oil Filters
Caterpillar oil filters are recommended. The interval for changing the oil filter should be 500 hours.Oil
The 6000 hour interval for changing the oil is specific to HYDO Advance 10.The 4000 hour interval for changing the oil is for the following oil types.
Caterpillar Hydraulic Oil (HYDO)
CaterpillarTransmission/Drive Train Oil (TDTO)
Caterpillar TDTO (TMS)
Caterpillar Diesel Engine Oil
Caterpillar Biodegradable Hydraulic Oil (HEES)
Caterpillar Multipurpose Tractor Oil (MTO)
Heavy-Duty Diesel Engine Oil with a minimum zinc content of 900 parts per million (ppm) Heavy-duty oils are identified by the following classifications: CF, CF-4, CG-4 and CH-4.Note: Industrial hydraulic oils are not recommended in Caterpillar hydraulic systems. These oils are more likely to cause corrosion and excessive wear.Monitoring the Condition of the Oil
The oil should be monitored during intervals of 500 hours. Caterpillar's standard S O S Fluids Analysis or an equivalent oil sampling program should be used.If an oil sampling program is not available, the standard 2000 oil change interval should be used.Measured Data
The following information should be monitored when you sample the oil:
Significant changes in wear metals should be monitored. These metals include iron, copper, chromium, lead, aluminum, and tin.
The following additives should be observed for significant changes: Zinc, calcium, magnesium and phosphorus.
Contaminants should not be present. These contaminants include fuel and antifreeze. Water content should be .5 percent or less.
The silicon level should not exceed 15 parts per million for new oil. The particle counts should be monitored.
The recommended level of cleanliness for Caterpillar machines that are operated in the field is ISO 18/15 or cleaner. The cleanliness should be monitored by particle count analysis. The levels of contamination should not exceed normal levels by more than two ISO codes. Action should be taken in order to determine the cause of the contamination. The system should be returned to the original levels of contamination.
There should not be significant changes in sodium, silicon, copper, and potassium.
The allowable level of oxidation is 40 percent (0.12 Abs units).
The kinematic viscosity at 100 °C (212 °F) should not exceed a 2 cSt change.Procedure for Changing the Hydraulic Oil
Care must be taken to ensure that fluids
