Removal (Fig. 68)
NOTE: The ports on the manifold are marked for easy
identification of components. Example: P1 is a piston

1. Read the General Precautions for Removing and
Installing Hydraulic System Components at the begin-
ning of this section.
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. Topreventcontaminationofhydraulicsystemduring
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
capsorplugsonopenhydraulic linesand 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, lubricateand
place new O--rings onto fittings. Install fittings intoman-
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 capsand plugsfromfittingsandhoses.Us-
