Description
The steering control unit can
provide steering flow when
the pump or engine fails. It
will pump oil through the
meter (gerotor) as the
operator applies input or
torque to the steering wheel
which provides limited
manual steering.
This feature is available in all
steering models except for
Series 25 and 40.
Use of Graph
1. Determine steering work
port pressure required to
preform the desired
steering maneuver from
vehicle test data. This
defines the approximate
manual steering pressure
level required. Find this
value on the vertical axis
and construct a horizontal
line on the graph.
2. Find the input torque limit
on the horizontal axis.
Follow this vertically until
it crosses the required
pressure line of step 1.
3. The maximum steering
unit displacement is
identified by the first
angled line to the left of
this intersection.
