Do not use the Cat GO (Gear Oil) or commercial gear oil in the machine compartments unless specifically recommended by AVSpare. The gear oil can cause seals to fail. The seals can also leak. The gear oil may not be compatible with friction materials. The oil can reduce the efficiency of the transmission and the brake performance. |
Gear oils are recommended for use in certain Direct Drive Transmissions, Differentials, Final Drives, Transfer drives, Circle Drives (excavators), and other applications. The details of the applications of these oils are given in the “Lubricant Viscosity” section of this Special Publication.
Cat GO offers maximum protection against the following damage: scoring of the gear teeth, pitting of the gear teeth and pitting of the parts in roller bearings. Cat GO provides excellent stability under high temperature conditions. Cat GO also has superior low temperature performance. This oil also gives protection against rust and corrosion. Some applications require additives for the extreme pressures that can occur at the surfaces/edges of the components. For these applications, Cat GO provides the extra protection.
When the use of gear oil is specified, use Cat GO or Cat Synthetic GO in order to maximize the component life.

Cat GO is not the same as Cat TDTO, and does not meet Cat TO-4 or TO-4M oil Performance Requirements. Cat GO or commercial gear oils should not be used in compartments that specify Cat TO-4 or TO-4M oil. |

|
Cat GO is not the same as Cat FDAO, and does not meet the Cat FD-1 oil Performance Requirements. Cat GO or commercial gear oil should not be used in compartments that specify Cat FD-1 oil. |

Cat does not warrant the quality or performance of non-Cat fluids. |
Gear lubricants are classified by the API service category and by the SAE viscosity grade that is defined in "SAE J306".
If the Cat GO or Cat Synthetic GO cannot be used, select a commercial oil that meets the "API GL-5"specification.
Note: Non-AVSpare commercial "API GL-5" gear oils are as a group second choice oils.
