STEERING CIRCUIT
Note:
Refer to
Hydraulic Manifold and Relief Pressure Adjustment Procedure.
Refer to
Section 3 for Remove and Replace instructions.
Refer to
Parts Section E for hose routing.
The steering system consists of the following components:
• Each wheel motor housings has a pivot and chain sprocket on the top.
• A hydraulic steering cylinder is mechanically linked via tie rods to two (2) chain-and-
sprocket assemblies (one [1] for each motor housing).
• Steering is accomplished
hydraulically by using
one (1) double-acting cylin-
der, and a 4-way 3-position
solenoid-operated, hydrau-
lic directional control car-
tridge valve.
Steer Cylinder
There is one (1) cylinder utilized in
the steering system. This cylinder is
a double acting double sided type
which requires fluid flow to operate
the cylinder rod in both directions.
Directing fluid forces the piston to
travel to one side or the other,
thereby extending one rod end and
retracting the other.
Refer to the Mechanical Section of
this manual for cylinder disassem-
bly, or replacement.
