The rear axle 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 Operation and Maintenance Manual, SEBU6250, "Lubricant Information - Cat® Fluids".
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, bevel gear, and two final drives to lubricate the components of the differential, bevel gear, and final drives.
