Removing the Lift Control Manifold (continued)
2. Clean the hydraulic hose ends and fittings on the lift control manifold to
prevent contaminants from entering into the hydraulic system.
3. For assembly purposes, label all the hydraulic hoses and electrical
connections.
4. Disconnect the hydraulic hoses from the fittings on the lift control manifold
and drain the hoses into a suitable container.
5. Install clean caps or plugs on the hydraulic hoses and fittings to prevent
system contamination.
6. Disconnect the wire harness connectors from the solenoid coils on the
manifold.
7. Support the manifold to prevent it from falling.
8. Remove the 2 bolts (item 17 in Figure 122 ) and 2 lock washers that secure
the manifold to the machine, and remove the manifold from the machine.
9. If the hydraulic fittings are to be removed from the lift control manifold, put a
mark on the fitting orientation for correct assembly.
10. Remove the fittings from the manifold and discard the O-rings.
Installing the Lift Control Manifold
1. If the hydraulic fittings were removed from the lift control manifold, lubricate
the new O-rings with clean hydraulic fluid, position the O-rings to the fittings,
and install the fittings into the manifold ports; refer to
Installing the Hydraulic
Fittings (SAE Straight Thread O-Ring Fitting into the Component Port) (page
4–7)
.
2. Position the lift control manifold to the machine and secure the manifold
with the 2 bolts and 2 lock washers.
3. Remove the caps and plugs from the hydraulic hoses and fittings.
4. Lubricate and install the new O-rings onto the control manifold fittings.
5. Use the labels that you attached during the manifold removal to correctly
connect the hydraulic hoses to the lift control manifold; refer to Installing the
Hydraulic Hose and Tube (O-Ring Face Seal Fitting) (page 4–5) .
6. Connect the wire harness connectors to the solenoid coils on the manifold.
7. Check the hydraulic-fluid level in the hydraulic reservoir and add correct
quantity of fluid if necessary; refer to the Traction Unit Operator’s Manual .
