Start By:

Install the steering frame lock. Refer to Disassembly and Assembly, "Steering Frame Lock - Remove and Install".
Release the pressure in the hydraulic system. 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. This action 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. This action helps to prevent fluid loss and helps to keep contaminants from entering the system.

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.
