7. Final Drive Oil and Swing Drive Oil

Applications • Power Shift Transmissions, Direct Drive Transmission, and Winches • Final Drives: Track Type Tractors, Pipelayers, Skidders, Loaders, and Track Type Excavators • Differentials and Final Drives: Wheel Tractors, Loaders, Skidders, Compactors, Motor Graders, Off-Highway Tractors, and Trucks Caterpillar TransmissionDrive Train Oil Caterpillar TransmissionDrive Train Oil is balanced in order to give maximum frictional material life in power shift transmissions. Caterpillar Transmission Drive Train Oil also eliminates brake chatter in wet brake applications in Caterpillar machines. This oil has passed the requirements for the TO-4 oil specification which includes the frictional requirements and gear wear requirements. This oil is offered in several viscosity grades for maximum component life at high ambient temperatures and for heavy-duty cycles. NOTICE This oil is formulated for transmissions and drive trains only, and should not be used in engines. Shortened engine life will result. Note: Do not use the Caterpillar Gear Oil in the machines that are listed above. The Gear Oil can cause seal material to fall. The seal material 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. Note: Multigrade oils are not blended by Caterpillar for use in transmissions. Multigrade oils which use high molecular weight polymers as polymer viscosity index improvers lose the viscosity effectiveness by temporary shear of the polymer viscosity index improver and by permanent shear of the polymer viscosity index improver. Multigrade oils are not recommended for these compartments. The TO-4 oil specifications do not include a test for the shear stability of multigrade oil. Multigrade oils with adequate shear stability may be available in the future. Commercial TransmissionDrive Train Oils If Caterpillar TransmissionDrive Train Oil is not used, commercial oils that meet the TO- 4 specification must be used: 142 • TO-4 Specification oils are single viscosity grade. Synthetic Base Stock Oils Synthetic base oils are acceptable for use in Caterpillar engines and in Caterpillar machines if these oils meet the performance requirements that are specified for a particular compartment. Each compartment has lubrication requirements and lubrication specifications in order to ensure proper lubrication and life of the system. Synthetic base oils generally perform better than conventional oils in the following two areas: • Synthetic base oils have improved viscosity at low temperatures especially in arctic conditions. • Synthetic base oils have improved oxidation stability especially at high operating temperatures. Some synthetic base oils have performance characteristics that enhance the service life of the oil. However, Caterpillar does not recommend automatic extending of the oil drain intervals for any type of oil. Oil drain intervals for Caterpillar diesel engines can only be adjusted after an oil analysis program that contains the following tests: • Oil condition and wear metal analysis Caterpillar SOS Oil Analysis • Trend analysis • Fuel consumption • Oil consumption
