1.1. Removal Procedure
Removal Procedure
Start By:
- Release the hydraulic system pressure. Refer to Disassembly and Assembly, "System Pressure - Release".
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 in order to prevent fluid loss and to keep contaminants from entering the system.
- Remove bolts (1) .
