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 Hydraulic Schematic
in Chapter 10 - 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 chapter. Refer
to Figure 91 for cartridge valve and plug installation
torque.

Figure 91
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 induced
plug loosening. The zero leak plugs also have an O- ring
as a secondary seal. If zero leak plug removal is neces-
sary, lightly rap the plug head using a punch and ham-
mer 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.
