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

5. #6 zero leak plug with O- -ring
NOTE: The filter 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 necessary,
lightly rap the plug head using a punch and hammer be-
fore using an allen wrench to remove the plug: the im-
pact will allow plug removal with less chance of damage
to the socket head of the plug.
