Applications
Hydraulic Systems
Hydrostatic TransmissionsCaterpillar Hydraulic Oil (HYDO)
Caterpillar Hydraulic Oil is formulated with a balanced additive system. The system includes the following agents: detergents, rust inhibitors, antiwear agents and defoamers. Caterpillar Hydraulic Oil offers the following benefits: protection against mechanical wear, protection against rusting, protection against corrosive wear in hydraulic systems and protection against wear in hydrostatic transmission systems. Caterpillar Hydraulic Oil should be used to achieve maximum life and maximum performance from hydraulic system components and from hydrostatic transmissions. Caterpillar Hydraulic Oil is recommended in most hydraulic systems and in most hydrostatic systems.
Caterpillar Hydraulic OilIf a different viscosity is required due to ambient temperatures, the following Caterpillar oils can be used:
Caterpillar Multigrade Diesel Engine Oil (DEO)
Caterpillar Single Grade Diesel Engine Oil (DEO)
Caterpillar Transmission/Drive Train Oil (TDTO)
Caterpillar Multipurpose Tractor Oil (MTO)Commercial Oils
If Caterpillar oils cannot be used, the following commercial classifications can be used in hydraulic systems and in hydrostatic transmission systems:
CG-4 engine oils that have a minimum zinc additive of 0.09 percent (900 ppm)
CF-4 engine oils that have a minimum zinc additive of 0.09 percent (900 ppm)
CF engine oils that have a minimum zinc additive of 0.09 percent (900 ppm)Caterpillar Biodegradable Hydraulic Oil (HEES)
Caterpillar has a biodegradable hydraulic oil that is available for use in machine hydraulic systems. This fluid is recommended for the hydraulic systems when environmental compliance is required or desired.
Illustration 1 g00106926
Machines with this symbol are filled with biodegradable hydraulic oil. This symbol is located on the hydraulic tank.This fluid is formulated with the following components: a saturated HEES (Hydraulic Environmental Ester Synthetic), synthetic base stock and selected additives. Use this oil only in hydraulic systems. Do not use the oil in compartments with brakes and clutches. If a machine is equipped with a jacket water cooling system, do not use Biodegradable Hydraulic Oil (HEES) in the machine's hydraulic system. Equipment such as large track-type tractors or off-highway trucks are equipped with a jacket water cooling system. Biodegradable Hydraulic Oil (HEES) is recommended for operation at tank temperatures of -32 to 100°C (-25 to 212°F). While the oil is in the specified range of temperatures, the oil has a viscosity that is similar to SAE 10W or to ISO VG 46.Caterpillar Biodegradable Hydraulic Oil (HEES) may become darker in color throughout the service life of the oil. Analysis is required to determine the quality of the oil.The maximum recommended water content for hydraulic systems that are filled with Caterpillar Biodegradable Hydraulic Oil (HEES) is 0.10 percent. If the water levels exceed 0.10 percent, the water should be removed or the oil should be replaced.Consult your Caterpillar dealer for additional information on this product and on the potential use.Commercial Biodegradable Hydraulic Oil (HEES)
If Caterpillar Biodegradable Hydraulic Oil (HEES) is not used, commercial oils which meet the Caterpillar BF-1 specifications should be used.
