Removal Procedure
 |
At operating temperature, the hydraulic oil is hot and under pressure. Hot oils can cause burns. To prevent possible personal injury, release the pressure in the implement hydraulic circuit (boom, stick, bucket, and swing), travel circuits, and the hydraulic oil tank at the filler cap before any hydraulic lines or components are disconnected or removed. Remove the filler cap only when the engine is stopped and the filler cap is cool enough to touch. |
 |
- Release the hydraulic system pressure. Refer to Disassembly and Assembly, "Hydraulic System Pressure - Release" in this manual.
- Remove four bolts (1) and the washers that hold cover assembly (2). Remove cover assembly (2) .

- When two hose assemblies (5) are disconnected from the travel brake valve, oil will flow from the hose assemblies. Collect the drain oil in a suitable container. Disconnect two hose assemblies (5) from travel brake valve (3). Put plugs in the ends of the hose assemblies. Plugs prevent oil loss. Plugs prevent contaminating the hydraulic system.
