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 cylinder,
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 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.
