Removal Procedure
Start By:
- Connect the steering frame lock. Refer to Disassembly and Assembly, "Steering Frame Lock - Separate and Connect".
- Remove the firewalls. Refer to Disassembly and Assembly, "Firewalls - Remove".
- Remove the hydraulic fan piston pump. Refer to Disassembly and Assembly, "Piston Pump (Hydraulic Fan) - Remove".
Note: 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: Put identification marks on all hoses, on all hose assemblies, on all wires, and on all tube assemblies for installation purposes. Plug all hose assemblies and all tube assemblies. This helps to prevent fluid loss, and this helps to keep contaminants from entering the system.
