Pump Pressure Check With T/N 07406 -
Check the fluid pressure as follows to determine whether
the trouble is in the pump or gearbox.
1. Check the power steering tluid level (see page 17-
151, and pump belt tension (see page 17-14).
2. Disconnect the pump outlet hose from the pump
outlet with care so as not to spill the power steering
fluid on the frame and other parts, then install the
P/S joint adapter (pump) on the pump outlet.

Start the engine and let it idle.
Turn the steering wheel from lock-to-lock several
times to warm the tluid to operating temperature.
Measure steady-state fluid pressure while the engine
is idling. It the pump is in good condition, the gauge
should read 1,500 kPa (15 koflcm',213 psi). lf it reads
high. check the outlet hose or valve body unit {see
General Troubleshooting),
Close the-pressure control valve gradually and read
the oressure.
CAUTION: Do not keep the pressurs control valve
closed more then 5 seconds or the pump could bo
damaged by overheating.
lmmediately open the pressure controlvalve fully.
lf the pump is in good condition, the gauge should
read at least 6,900 - 7;800 kPa (70 - 80 kgflcm',
1,000 - 1.140 psi), A low reading means pump out-
Dut is too low for {ull assist. Repair or replace the
oumo.

Master Cylinder
I nspection/Disassembly
CAUTION: Do not spill brake fluid onthe vehicle; it may
damsge the paint; il brake fluid does contact th6 paint.
wash it off immodiately with water.
NOTE:
. Before reassembling, check that all parts are free of
dust and other foreign particles.
. Do not try to disassemble the master cylinder assem-
bly. Replace the master cylinder assembly with a new
pan it necessary,
. Make sure no dirt or other foreign matter is allowed
to contaminate the brake fluid.

Pushrod Clearance Adjustment
NOTE: Master cylinder pushrod-to-piston clearance must
be checked and adjustments made, if necessary. before
installing the master cylinder.
1. Set the special tool on the master cylinder body;
push in the center shaft until the top ot it contacts
the end of the secondary piston by turning the ad-justing nut.

A/G System Service
Performance Test
The performance test will helD determine if the air con-
ditioner system is operating within specifications.
Use only service equipment that is U.L.-listed and is cer-
tified to meet the requirements of SAE J2210 to remove
HFC-134a (R-134a) from the air conditioner svstem.
CAUTION: Exposure to air condiiioner r€trigerant and
lubricant vapor or mist can irritate €yes, nose and
throat. Avoid bre8thing the air conditioner retrige.ant
and lubricant vapor or mist,
lf accidental system discharge occurs. ventilate work
area before resuming service.
R-134a service equipment o. vehicle air conditioner sys-
tems should not be pressure tested or leak tested with
comDressed air.
@ some mixtur€s ol air and R-134a have becn
shown to be combuslible at olsvated pressures and can
result in lire or explosion causing iniury or property
damage. Never use compressed air to prgssure test R-
13i[a service equipment or vehicle air conditioner sys.
tems.
Additional health and safety information may be obtained
from the refrigerant and lubricant manufacturers.
Recovory/Recycling/charging station
LOW.PRESSURESIDE
1.Connect a R-134a refrigerant recover/recycling/
charging station to the vehicle, as shown. following
the equipment manufacturer's instructions,
Insen a thermometer in the center air vent. Determine
the relative humidity and air temperature.
Test conditions:
. Avoid direct sunlight.
o Open hood.
. open front doors.
. Set the temperature control dial on MAX COOL,
the mode control dial on VENT and the reci.cula-
tion control switch on RECIRCULATE.
. Turn the A,/C switch on and the fan switch on
MAX.
. Run the engine at 1,500 rpm.
. No driver or passengers in vehicle
After running the air conditioning for 10 minutes
under the above test conditions, read the deliverv
temperature from the thermometer in the dash vent
and the high and low system pressure from the Ay'Cgauges.

5. To comDlete the charts:
. Markthe delivery temperature along the vertical line'
. Markthe intake temperature {ambient air temperature) along the bottom line'
. Draw a line straight up from the air temperature to the humidity'
. Mark a point 10% above and 10% below the humidity level'
a From each point, draw a horizontal line across the delivery temperature'
. The deliverv temperature should fall between the two lines'
. Complete the low-side pressure test and high-side pressure test in the same way'
. Anv measurements outside the line may indicate the need for further inspection

order of disassembly. Make note of the following
rrems.
Install the field coil with the wire side facing down,
and align the boss on the tield coil with the hole in
the compressor.
Clean the rotor pulley and compressor sliding
surfaces with non-oetroleum solvent.
lnstall new snap rings A and B.
Make sure the snap rings are fully seated in the
groove.
Make sure that the rotor pulley turns smoothly
