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 of the flow divider cartridge valve). See Hydrau-
lic Schematic in Chapter 9 -- Foldout Drawings to identify
the function of the hydraulic lines and cartridge valves
at each port location.
For cartridge valve service procedures, see Control
Manifold Cartridge Valve Service in this section. Refer
to Figure 87 for cartridge valve and plug installation
torque.

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 impact will allow plug removal with less chance
of damage to the socket head of the plug.
