Removal (Fig. 68)
NOTE: The ports on the manifold are marked for easy
identification of components. Example: P1 is a piston
pump connection port and SV is the location for the sole-
noid valve (see Hydraulic Schematic in Chapter 10 --
Foldout Drawings to identify the function of the hydraulic
lines and cartridge valves at each port).
1. Read the General Precautions for Removing and
Installing Hydraulic System Components at the begin-
ning of this section.
NOTE: Removal of the radiator (see Radiator Removal
in the Service and Repairs section of Chapter 3 -- Kubota
Diesel Engine) or rear axle (see Rear Axle Assembly
Removal in the Service and Repairs section of Chapter
6 -- Axles, Planetaries and Brakes) will improve access
to 4WD manifold.
2. To prevent contamination of hydraulic system during
manifold removal, thoroughly clean exterior of manifold
and fittings.
3. Disconnect wire harness connector from the sole-
noid valve.
4. Disconnect hydraulic lines from manifold and put
caps or plugs on open hydraulic lines and fittings. Label
disconnected hydraulic lines for proper installation.
5. Remove hydraulic manifold from the frame using
Figure 68 as guide.
6. If hydraulic fittings are to be removed from manifold,
mark fitting orientation to allow correct assembly. Re-
move fittings from manifold and discard O--rings.

Installation (Fig. 68)
1. If fittings were removed from manifold, lubricate and
place new O--rings onto fittings. Install fittings into man-
ifold openings using marks made during the removal
process to properly orientate fittings. Tighten fittings
(see Hydraulic Fitting Installation in the General Infor-
mation section of this chapter).
2. Install hydraulic manifold to the frame using Figure
68 as guide.
3. Remove caps and plugs from fittings and hoses. Us-
ing labels placed during manifold removal, properly con-
nect hydraulic lines to manifold (see Hydraulic Hose and
Tube Installation in the General Information section of
this chapter).
4. Connect wire harness connector to the solenoid
valve.
5. Make sure hydraulic tank is full. Add correct oil if nec-
essary before returning machine to service.
