Hydraulic Oil
Cat Hydraulic Oil (HYDO)
Cat Hydraulic Oil is formulated with a balanced additive system, including detergents, rust inhibitors, antiwear agents and defoamers. It will offer maximum protection against mechanical wear, rusting and corrosive wear in all hydraulic and hydrostatic transmission systems.Cat Hydraulic Oil should be used to achieve maximum life and performance from hydraulic system components and hydrostatic transmissions. Use of Cat Hydraulic Oil is recommended in most hydraulic and hydrostatic systems.* Cat Hydraulic Oil (HYDO)If higher viscosities are required because of high ambient temperatures, the following Caterpillar oils can be used: * Cat Diesel Engine Oil DEO (CF-4)* Cat Diesel Engine Oil DEO (CD)* Cat Transmission/Drive Train Oil (TDTO)Biodegradable Hydraulic Oil (BIO HYDO)
Caterpillar now has available a biodegradable oil for use in machine hydraulic systems and hydrostatic transmissions. This oil meets the stringent requirements for the hydraulic system components and satisfies customer needs for a hydraulic oil that is readily biodegradable and nontoxic.This oil is formulated with vegetable based oil from the rape seed and selected additives. This oil is to be used in hydraulic systems only, and not in compartments with brakes, clutches, etc. Use of the BIO HYDO is not recommended for operation at tank or actual oil temperatures below -7°C (20°F) or above 82°C (180°F). The oil within the specified temperature range has a viscosity similar to an SAE 10W Oil or the ISO VG of 32 to 46.Contact your Caterpillar dealer for additional information on this new product and its potential use.Commercial Oils
If Cat oils cannot be used, the following commercial classifications can be used in the hydraulic and hydrostatic transmissions: * API CF-4/SG, CE/SG, or CD/SG* MIL-L-2104EPremium industrial hydraulic oils that have passed the Vickers vane pump test (35VQ25) and/or have a minimum of 0.09% zinc additive may also be used. These oils should have antiwear, antifoam, antirust and antioxidation additives for heavy duty use as stated by the oil supplier. ISO viscosity grade of 46 would normally be selected.Power Shift Transmission Oil
Cat Transmission/Drive Train Oil (TDTO)
Cat Transmission/Drive Train Oil is balanced to give maximum frictional material life in power shift transmissions and eliminate brake chatter in wet brake applications. Manual transmissions which have had the API CD/Cat TO-2 oil recommendation should now use this oil. This oil has passed the requirements for the new Caterpillar TO-4 oil specification which not only includes the frictional requirements, but also has gear wear requirements.This oil should be used for lubrication of winch, clutch plates, gears and bearings.This oil is offered in several viscosity grades, including SAE 50, for maximum component life at high ambient temperatures and heavy duty cycles.Maximum transmission life and performance can be achieved, by using: * Cat Transmission/Drive Train Oil (TDTO)
This oil is formulated for transmissions and drive trains only, and should not be used in engines. Shortened engine life will result.
Multigrade oils are currently not blended by Caterpillar for use in transmissions. Multigrade oils which use high molecular weight polymers as viscosity index improvers
