Front Steering System

Troubleshooting

Table 8-1

Functional Check

A normal periodic functional check of the entire steering
system will generally be adequate to ensure satisfactory
service.

1.

Check all fittings for leakage. An accumulation of moist,
black dirt is a good indication of leakage.

2.

With the engine running at idle and at full throttle, and
with  the  machine  standing  still  and  moving,  turn  the
steering wheel through the full range of travel. Note any
speed  irregularities  and  sticky  sensation.  This  may
indicate dirt in the fluid. If the steering wheel continues to
rotate when started and released, a condition known as
Motoring exists. This may also indicate dirty fluid in the
system.

3.

Ensure  the  system  has  adequate  power.  If  there  is  an
indication of hard steering, this can be caused by either

a  reduced  oil  flow  to  the  control  valve  or  a  reduced
system  relief  pressure.  Adequate  oil  flow  under  all
conditions can best be checked by timing the full travel
of  the  cylinder  with  the  steered  axle  unloaded  and
loaded. If there is a great difference at low engine speed
and  slight  difference  at  high  engine  speeds  this  may
indicate  a  defective  pump  drive.  Refer  to 

Checking/

Setting the Front Steer Pressure

, page 2-61.

Front Steering Control Valve

The steering control valve is located under the dash and is
actuated by a conventional steering wheel and steering
column, providing precise, full hydraulic steering. Precise
steering is accomplished by a metering system within the
valve that is directly connected to the steering column and
wheel.
