Operation of the Rear Axle Hydraulic System
This hydraulic system lubricates the bearings for the differential and bevel gear and the bearings for the final drives. This hydraulic system also cools the bearings for the differential and bevel gear and the bearings for the final drives. This hydraulic system is independent from the other hydraulic systems. For the correct oil that should be used in the system, refer to the Operation and Maintenance Manual for your machine.The rear axle housing acts as a common sump for the differential and bevel gear and the two final drives. Oil is thrown by the differential and bevel gear and the two final drives in order to lubricate the components of the differential and bevel gear and the final drives.
