Removing the Hydraulic Manifold (continued)
7. Label and remove the hydraulic tubes and hoses from the fittings on the
manifold. Allow the tubes and hoses to drain into a suitable container.
8. Install clean caps and plugs on the hydraulic tubes, hoses, and fittings to
prevent system contamination.
9. Label and disconnect the wire harness connectors from the solenoid valves.
10. Support the manifold assembly, remove the fasteners and lower the manifold
assembly from the machine.
11. Dismantle the manifold assembly if necessary; refer to Hydraulic Manifold
Service (page 5–90) .
Installing the Hydraulic Manifold
Refer to Figure 61 for this procedure.
1. Ensure that all manifold components are properly installed prior to installing
the manifold into the machine; refer to Hydraulic Manifold Service (page
5–90) .
2. Fit the manifold to the machine and secure it with the previously removed
fasteners. Tighten the cap screws from 36 to 44 N·m (27 to 33 ft-lb) .
3. Remove the caps and plugs then connect the hydraulic tubes and hoses to
the manifold fittings; refer to Installing Hydraulic Hoses and Tubes (O-Ring
Face Seal Fitting) (page 5–7) .
4. Connect the wire harness connectors to the solenoid valves.
5. Install a new hydraulic fluid filter:
A. Fill the filter with hydraulic fluid and lubricate the filter gasket with
hydraulic fluid.
B. Ensure that the filter-mounting area is clean and screw the filter on until
the gasket contacts the manifold.
C. Tighten the filter an additional 1/2 turn.
6. Install the fuel tank; refer to Removing and Installing the Fuel Tank (page
