a 'lte
Inch open end wrench can be fttte4 to

2. Disconnect the pressure line
hose from the pump outlet, and install
a 0-2000 psi pressure gauae and shut
off valve between the end of the hose
and the pump outlet
(Fig.
3).
7. Increase the engine speed to
1000 rpm; then, slowly close the
gause shut-off valve. With the valve
fully closed, the pump pressure
should be 1275 ±50 psi.
Do not close the •alve for more
than
a
few seconds (maximum
5
ICC•
onds), as tbls
would abnormally In·
crease

If pressure Is more or

~embly.
If
the preceding test results are
satisfactory, proceed as
follows:
8.
Open the shut off valve fully,
and run the engine at 1000 rpm.
9.
Turn the steering wheel to full
lock and read the pressure. If the
pressure is not to specification,
1275
t
50 psi, the steering gear is at
fault and must be removed for repair.
Do not hold the steering gear
against the stop for more than
S
seconds.
FRONT WHEEL ALIGNMENT
CHECKS
Do not attempt to check and ad-
just
front wheel alignment without
first
making a preliminary inspection
of the front-end parts.
Chec)( all the factors of front wheel
alignment except the turning angle
before making any
adjustment~.
The
harping angle should be checked only
after caster, camber, and toe-in have
been adjusted to
specification.
,IG. 2 -Checking Turning Effort-Typical
The front wheel" alignment speci-
fications, given in Part 3-7 are cor-
rect
only when the
car
is
at
"Curb
Height." Before checking or adjust-
ing the alignment factors, the sus-
pension alignment spacers (Tool
T65P3000-B) must be installed to
obtain the curb heights.

3.
Connect a tachometer.
4. Start the engine and operate it
at idle speed for at least two minutes
to warm up the fluid.
5. Cycle the steering wheel ti'om
stop-to-stop several times to expel
any air from the system; stop the
engine. Remove the reservoir filler
cap and check the fluid level in the
reservoir. If necessary, add fluid to
the proper level.
8. With the engine running at ap-
·
proximately 500 rpm and no steer-
ing effort applied, and the fluid at
normal operating temperature, the
pressure gauge should show a pres-
sure of less than 50 psi. If the pres-
sure is higher, inspect the hoses for
kinks and obstructions.
