Removal Procedure
Start By:
- Install the wheel chocks. Refer to Disassembly and Assembly, "Wheel Chock (Front and Rear) - Remove and Install".
- Connect the frame lock link. Refer to Disassembly and Assembly, "Frame Lock Link - Separate and Connect".
- Release the hydraulic system pressure. Refer to Disassembly and Assembly, "Hydraulic System - Pressure Release/Charge".

Care must be taken to ensure that fluids are contained during performance of inspection, maintenance, testing, adjusting and repair of the product. Be prepared to collect the fluid with suitable containers before opening any compartment or disassembling any component containing fluids. Refer to Special Publication, NENG2500, "Caterpillar Tools and Shop Products Guide" for tools and supplies suitable to collect and contain fluids on Caterpillar products. Dispose of all fluids according to local regulations and mandates. |

Personal injury can result from hydraulic oil pressure and hot oil. Hydraulic oil pressure can remain in the hydraulic system after the engine has been stopped. Serious injury can be caused if this pressure is not released before any service is done on the hydraulic system. Make sure all of the attachments have been lowered, oil is cool before removing any components or lines. Remove the oil filler cap only when the engine is stopped, and the filler cap is cool enough to touch with your bare hand. |

Keep all parts clean from contaminants. Contaminants may cause rapid wear and shortened component life. |
Note: Install caps and plugs on all openings in order to prevent dirt or debris from entering the system. Cleanliness is an important factor. Before the removal procedure, the exterior of the component should be thoroughly cleaned. This will help to prevent dirt from entering the internal mechanism.
Note: For easier assembly, mark all hose assemblies, tube assemblies, wire harnesses and cables for identification purposes.
- Turn the battery disconnect switch to the OFF position.
- Remove drain plug (1) in order to drain the hydraulic tank. Refer to Operation and Maintenance Manual, "Hydraulic System Oil - Change" for the correct procedure to drain the hydraulic tank. The capacity of the hydraulic tank is 723 L (191 US gal).
