NOTE: The ports on the fan control manifold are
marked for easy identification of components (e.g. ST is
the supply to the steering control valve and FD is the
location ofthe flowdivider cartridge valve). SeeHydrau-
licSchematicsinChapter9 -- FoldoutDrawingstoidenti-
fy the function of the hydraulic lines and cartridge valves
at each port location.
NOTE: The fan control manifold includes several zero
leak plugs. These plugs have a tapered sealing surface
on the plug head that is designed to resist vibration in-
duced plug loosening. The zero leak plugs also have an
O--ring as a secondary seal. If zero leak plug removal is
necessary, lightly rap the plug head using a punch and
hammer before using an allen wrench to remove the
plug:the impactwill allowplug removal with lesschance
of damage to the socket head of the plug.
For solenoid and control valve service procedures, see
4WD/2WD Control Manifold Service in this section. Re-
fer to Figure 96 for cartridge valve and plug installation
