Applications
Hydraulic systems
Hydrostatic transmissionsCaterpillar has developed a new class of hydraulic oils, the HYDO Advanced fluids. These new advanced fluids are designed for optimal performance in new advanced hydraulic systems that are designed with close tolerances for precise operation and that operate under demanding conditions of temperatures and pressures. These fluids ensure optimal performance in current and previous hydraulic systems. Four new products have been introduced:
HYDO Advanced 10 , SAE 10W
HYDO Advanced 20 , SAE 20W
HYDO Advanced 30 , SAE 30
Bio HYDO Advanced , MultigradeCat HYDO Advanced Hydraulic Oils, SAE 10W, SAE 20W, and SAE 30
Cat HYDO Advanced hydraulic oils are designed to provide extended oil drain intervals and to provide extra protection to Cat hydraulic system components and hydrostatic transmissions.Cat HYDO Advanced hydraulic oils are formulated of premium additives and premium base stocks that pass severe qualification testing requirements, in the field and in the laboratory, to provide superior protection for Cat hydraulic systems.Cat HYDO Advanced hydraulic oils are preferred in most hydraulic systems and in most hydrostatic systems. Refer to this Special Publication, Lubricant Viscosities, Table Hydraulic Systems Lubricant Viscosities for Ambient Temperatures for the ambient operating temperatures for Cat HYDO Advanced hydraulic oils.Cat HYDO Advanced oils allow 6000 hours or higher oil drain intervals for most applications. S.O.S Services oil analysis is recommended when the oil drain interval is increased to 6000 hours or higher. In comparison, non-Cat commercial hydraulic oils (second choice oils) allow 2000 hours oil drain interval. Follow the maintenance interval schedule for oil filter changes and for oil sampling that is stated in the Operation and Maintenance Manual for the particular machine. Consult your Cat dealer for details.Cat HYDO Advanced hydraulic oils offer the following benefits:
Enhanced anti-wear protection : protects wear surfaces and reduces component wear in various hydraulic pumps
Protection against rusting and corrosive wear
Dispersion of water prevents pump damage due to water ingestion and prevents system damage due to freezing of water
250% increase in oxidation stability per ASTM D943
Rapid air release protects against cavitation
Improved filtration properties helps support component cleanlinessCat HYDO Advanced oils, when switching to Cat HYDO Advanced oils, cross contamination with the previous hydraulic oil should be kept to less than 10%.If a different viscosity is required due to ambient temperatures, the following Caterpillar oils can be used:
Cat DEO-ULS and Cat DEO
Cat DEO-ULS SYN and Cat DEO SYN
Cat DEO Cold Weather
Cat TDTO
Cat TDTO Cold Weather
Cat TDTO-TMS
Cat MTONote: Caterpillar oil availability will vary by region.Note: Oil drain intervals of the oils listed above are less than the intervals of Cat HYDO Advanced oils. The oil drain intervals of these oils are typically 2000 hours and up to a maximum of 4000 hours. An exception is Cat TDTO Cold-Weather oil which allows 6000 hours or higher oil drain interval. SOS Services Oil Analysis is required when the oils listed above are used in Cat hydraulic system components and hydrostatic transmissions.For applications requiring the use of fire-resistant hydraulic fluids, Caterpillar recommends the use of EcoSafe FR-46.
