Removal (Fig. 29)
1. Park machine on a level surface, lower rear attach-
ment, stop engine, apply parking brake and remove key
from ignition switch.
2. Read the General Precautions for Removing a nd
Installing Hydraulic System Components at the begin-
ning of this section.
3. To prevent contamination of hydraulic system during
manifold removal, thoroughly clean exterior of control
manifold and fittings.
WARNING
Make sure that rear attachment lift frame is fully
lowered before loosening hydraulic lines from
control manifold. If lift frame is not fully lowered
as hydraulic lines are loosened, lift frame may
drop unexpectedly.
4. Label all wire harness connectors that attach to
solenoid coils on control manifold. Make sure to identify
the upper (raise) and lower (lower) coil connections.
Disconnect wire harness connectors from solenoid coils
on the control manifold.
5. Disconnect hydraulic hoses from manifold and put
caps or plugs on open hydraulic hoses and fittings. La-
bel disconnected hydraulic hoses for proper installation.
6. Remove control manifold from the frame using Fig-
ure29asaguide.
7. If necessary, remove fittings from manifold and dis-
card O- rings.
Installation (Fig. 29)
1. If fittings were removed from manifold, lubricate and
place new O- rings onto fittings. Install fittings into man-
ifold openings and tighten fittings (see Hydraulic Fitting
Installation in the General Information section of this
Chapter).
2. Install control manifold to the frame using Figure 29
as a guide.
3. Remove caps and plugs from fittings and hoses. Us-
ing labels placed during manifold removal, properly con -
nect hydraulic hoses to manifold (see Hydraulic Hose
and Tube Installation in the General Information section
of this Chapter).
4. Using labels made during manifold removal, c onnect
wire harness c onnectors to the solenoid coils on the
control manifold.
5. Make sure hydraulic reservoir on the right side of the
machine is full. Add correct oil if necessary before re-
turning machine to service.
