i!Od possible
causes.
Several of these
symptoms are
also
common
to sus-
pension frame, and wheel and
tyre
troubles. For
this
reason, be
sure that
the cause of
the trouble is
in the
steering gear or linkage before adjust-
ing, repairing.
or
replacing
any
of the
steering
parts.
POWER STEERING
PRELIMINARY TESTS
The
following preliminary
checks
should '\!ways be
made before
per-
forming
any trouble-shooting opera-
tions.
Check Pulhp lelt
If
the pump belt is broken,
glazed,
or
worn,
replace
with
a new
belt.
Use
only the specified type of belt.
Check The lelt Tension
If the
belt
is too loose or
too
tight,
it should be
adjusted
to the proper
tension as outlined on Page 3-25.
·
A "used belt" Is one that has run
10 minutes or longer.
Check Fluid Level
Run the engine until the fluid is at
normal operating
temperature (165
degrees
F
to 175 degrees
F).
Then
turn the
steering wheel all the
way to
the left and
right
several times, and
shut off the
engine.
Check the
fluid
level in the power
steering
reservoir.
The level must show
on the cross
hatching between
the
bottom of the
Dipstick
and the full
mark (Fig.
I).
If the level
is low, add
automatic transmission
fluid
M2C33F.
Do not overfill the reservoir.
Check For Pluld Leaks
1.
If the power
steering ftuid
does not
already include yellowish
FIG. 1
Power Steering Pump
Dipstick
green
dye, pre-mix one teaspoonful
of
oil-soluble aniline dye with 2
pints
of
automatic transmission ftuid
M2C33-Ft.
Then refill the
reservoir
with the dye
solution.
l. With the eng10e running at idle
speed,
turn the steering wheel all the
way to the
right stop and to the left
stop several
times to distribute the
dye solution
throughout the hydraulic
system.
Do not hold the wheel against
each
wheel
stop
for more than
3
to
S seconds.
3. Shut
off
the
engine. and check
for
leaks.
Fitting and Tube Seat Leak.
Since
mo~t
fluid
leaks occur at
the fittings
and
connections
in a power
steering
hydraulic
system, these
parts should
be checked before any other
part
is
replaced.
Dirt, oil, and
grease should
be removed
from all areas where
leaks may
ex.ist.
If the fittings and
conn~:ctions
do not
leak, check the
other
parts of the
~~m.
.
Check
the hose connection at
the
pump
for leaks, and tighten
the hose
clamp if
necessary.
Pump Leaks.
If
leakage occurs at
the pump reservoir
seal,
pump outlet
valve seals,
or the support
stud seal,
check the torque of the outlet valve
nut and the support stud aut. If
torque is within specifications, replace
the reservoir seal, outlet valve seals,
or the support stud
seal,
whichever is
required if leaks are evident other
than the lines.
Steering
gear
leaks. Should
a
leak
be found in the steering gear
it
will
be necessary
to
remove the gear
to
effect
repairs. Preloads must be reset
after
se.
a l replacement. (See Page
3-20)'
Check Turning lffort
With
the front
wheels properly
aligned
and tire
pressures correct.
check
the effort
required to turn the
ateerina wheel.
1.
With the car on dry concrete,
set the parkin1
.
brakes.
2.
With the eaaine warmed up and
runnin1 at idle speed, tum the
steer·
ina wheel to the left and riaht several
times
to
warm the fluid.
3.
Attach
a
torque wrench
to
the
ateerina
wheel
hub.
lFig.
2).
Check
the effort required to tum the wheel
at least one complete revolution in
both directions. The torque should be
approximately
equal
in
both direc-
tions.
Pump-fluid Pressure Test
A
ftuid pressure test will show
whether the pump or some other unit
in the power steerina system
is
caus-
inJ trouble in the
system.
Steps out-
lined below
should be
followed to de·
termine the cause of the trouble.
I. Measure the pump belt
tension.
When adjuadaJ the belt tensloa oa
the power ateerin1 pump, do aot pry
