NOTE: The ports on the manifold are marked for easy
identification of components. Example: P1 and P2 are
gear pump connection ports and S1 is the solenoid valve
port (see Hydraulic Schematic in Chapter 10 -- Foldout
Drawings to identify the function of the hydraulic lines
and cartridge valves at each port).

NOTE: The fan drive manifold uses 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.
