Removal Procedure
Start By:
- Remove the counterweights. Refer to Disassembly and Assembly, "Counterweight Sections - Remove and Install" for the machine that is being serviced.
Note: Cleanliness is an important factor. Before the disassembly procedure, the exterior of the component should be thoroughly cleaned. This will help to prevent dirt from entering the internal mechanism.

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. |

Note: Put identification marks on all lines, on all hoses, on all wires, and on all tubes for installation purposes. Plug all lines, hoses, and tubes. This helps to prevent fluid loss and this helps to keep contaminants from entering the system.
Note: The counterweight frame was removed for photographic purposes.
- Drain the hydraulic oil into a suitable container for storage or disposal. Refer to Operation and Maintenance Manual, SEBU7160, "Hydraulic System Oil - Change" for the correct procedure.
