NOTE: The ports on the manifold are marked for easy
identification of components. Example: P1 is the gear
pump connection port and SV is the location for the sole-
noid cartridge (See Hydraulic Schematics to identify the
function of the hydraulic lines and cartridge valves at
each port).
NOTE: The hydraulic manifold shown in Figure 46.1
uses several zero leak plugs. These plugs have a ta-
pered 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 before using an allen
wrench to remove the plug: the impact will allow plug re-
moval with less chance of damage to the socket head of
the plug.
