Start By:
- Install the steering frame lock. Refer to Disassembly and Assembly, "Steering Frame Lock - Remove and Install".
- Release the hydraulic system pressure. Refer to Disassembly and Assembly, "System Pressure - Release".
Note: Cleanliness is an important factor. Before the removal procedure, thoroughly clean the exterior of the component. Thoroughly cleaning the exterior of the component will help to prevent dirt from entering the internal mechanism.
Note: Put identification marks on all lines, on all hoses, on all wires and on all tubes for installation purposes. Plug all lines, all hoses, and all tubes in order to prevent fluid loss and contaminants from entering the system.
Note: Put orientation and location marks on all fittings for installation purposes.

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.

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 work tools have been lowered to the ground, and the 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. |
