Removal (Fig. 74)
1. Read the General Precautions for Removing and
Installing Hydraulic System Components at the begin-
ning of the Service and Repairs section of this chapter.
NOTE: Removaloftheradiator(seeRadiatorRemoval
intheServiceandRepairssectionofChapter3--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. Disconnect wire harness connector from the sole-
noid valve coil.
3. Topreventcontaminationofhydraulicsystemduring
manifold removal, thoroughly clean exterior of manifold
and fittings.
4. Disconnect hydraulic lines from manifold and put
capsorplugsonopenhydraulic linesand fittings.Label
disconnected hydraulic lines for proper installation.
5. Remove hydraulic manifold from the frame using
Figure 74 as a guide.
6. Ifhydraulic fittings are to be removed from manifold,
mark fitting orientation to allow correct assembly. Re-
move fittings from manifold and discard O--r ings.
Installation (Fig. 74)
1. Iffittings 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
74 as a guide.
3. Removecapsandplugsfromfittingsandhoses.Us-
