NOTE: The ports on the manifold are marked for easy
identification of components. Example: P1 is a piston
pump connection port and 2 is the location for the sole-
noid valve (See Hydraulic Schematic to identify the
function of the hydraulic lines and cartridge valves at
each port).

Valve Cartridge Service
NOTE: The Groundsmaster 4100--D four wheel drive
manifold uses several zero leak plugs. These plugs
have a tapered sealing surface on the plug head that is
designed to resistvibration induced plug loosening. The
zeroleakplugsalsohaveano--ringasasecondaryseal.
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
