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.
If you are experiencing problems with your rear axle lubrication system, check the following components:
- Oil Filter
- Bypass Switch
- Control Manifold
- Solenoid Valve
A clogged filter could lead to high oil temperatures and other problems within the rear axle. If there is failure of a switch, sensor, valve, or manifold, then there may be several associated problems with the rear axle lubrication.
