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/SGPremium 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.Transmission Oil
Cat Transmission/Drive Train Oil (TDTO)(TO-4)
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 lose their viscosity effectiveness by permanent and temporary shear of the viscosity index improver.Multigrade oils therefore, are not recommended for transmission and drive train compartments. The Cat TO-4 spec does include a test for multigrade oil shear stability and multiviscosity oils with adequate shear stability may be available in the future.Commercial Oils
If the Cat Transmission/Drive Train Oil is not used, then commercial oils meeting the Caterpillar TO-4 specification should be used:* TO-4 Specification Oils Failure to follow this recommendation can cause shortened transmission life due to material incompatibility, inadequate frictional requirements for disk materials and/or excessive gear wear.Differential Oil
Cat Transmission/Drive Train Oil (TDTO)(TO-4)
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. 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 is offered in several viscosity grades, including SAE 50, for maximum component life at high ambient temperatures and heavy duty cycles. Do not use Cat Gear Oil (GO) in the final drives or differentials. Gear Oil can cause seal material to fail and possibly leak oil.For maximum life and performance of the differential and final drive components, select the correct viscosity of Caterpillar's:* Cat Transmission/Drive Train Oil (TDTO)Commercial Oils
If the Cat Transmission/Drive Train Oil is not used, then commercial oils meeting the Caterpillar TO-4 specification should be used:* TO-4 Specification OilsSynthetic Base Stock Oils (SPC)
