NOTE: The ports on the manifold are marked for easy
identification of components (e.g. P1 is a piston pump
connection port and SV is the location for the solenoid
valve). See Hydraulic Schematic in Chapter 9 -- Foldout
Drawings to identify the function of the hydraulic lines
and cartridge valves at each port.
NOTE: The 4WD/2WD control manifold uses several
zero leak plugs. These plugs have a tapered sealing
surface on the plug head that is designed to resist vibra-
tion induced plug loosening. The z ero leak plugs also
havean O--ring asa secondary seal. Ifzero leak plugre-
moval is necessary, lightly rap the plug head using a pin
punch and hammer before using an allen w rench to re-
move the plug: the impact will allow plug removal with
less chance of damage to the head of the plug.
For cartridge valve service procedures, see Control
Manifold Cartridge Valve Service in this section. Refer
to Figure 62 for 4WD/2WD Control Manifold cartridge
valve and plug installation torque.
IMPORTANT: A flow control orifice (item 3) is lo-
cated beneath t he plug in 4WD/2WD control man-
ifold ports OR1 and OR2. If an orifice is removed
from these manifold ports, make sure to label its
position for assembly purposes. When installing
the orifice in the manifold, make sure that the orifice
is properly tightened in the port.
IMPORTANT: An orifice disc (item 4) is located be-
neaththe4WD/2WDcontrolmanifoldsolenoidvalve
(SV). If this valve is removed from the manifold,
make sure to remove orifice a nd label its position
for assembly purposes. When installing the orifice
in the manifold, make sure that the orifice is flat in
the base of the port.
