WARNING
If lift manifold is attached to machine, make sure
that cutting decks are fully lowered before loos-
ening hydraulic lines, cartridge valves or plugs
from lift manifold. If decks are raised as compo-
nents are loosened, decks may drop unexpect-
edly.
For solenoid and control valve service procedures, see
4WD/2WD Control Manifold Service in this section. Re-
fer to Figure 100 for cartridge valve and plug installation
torque.
IMPORTANT: A flow controlorifice(item 6) isplaced
beneath the hydraulic fitting in lift control manifold
port C2. If this fitting is removed from the manifold,
make sure to remove orifice and label its position
for assembly purposes. Also note location of
groove in orifice for assembly purposes. When
installing the orifice in the manifold, make sure that
the orifice is flat in the base of the port. Manifold
damage is possible if the orifice is cocked in the
port.
