Compressor
Glutch Inspection
Check the plated parts ot the pressure plate tor color
changes. peeling or other damage. lf there is dam-
8ge, replace the clutch set.
Check the pulley bearing play and drag by rotating
the pulley by hand. Replace the clutch set with a new
one if it is noisv or has excessive play/drag
Measure the clearance betlveen the pulley and the
pressure plate all the way around. lf the clearance is
not within specified limits, the pressure plate must be
removed and shims added or removed as required.
Jollowing the procedure on page 22-33.
Clearrnce: 0.50 t 0.15 mm {0.02 i 0.01 inl
NOTE: The shims are available in three thicknesses:
0.1 mm, 0.3 mm and 0.5 mm.

5. lnstall in the reverse order of removal, and:
install the field coil with the wire side facing
down (see above).
clean the pulley and compressor sliding surfaces
with non-petroleum solvent.
check the pulley bearings for excessive play.
make sure the snap rings are in the groove prop-
efly.
apply locking agent to the threads of the center
bolt, and tighten it securelY
make sure that the pulley turns smoothly after
it's reassembled.
1. Remove the relief valve and the O-ring.
NOTE:
. Do not let the compressor oil run out.
. Make sure there is no foreign matter in the sys-
tem.
RELIEF VALVE13.2 N.m {1.35 kgtm,9.76lbtftl
2. lnstall and tighten the relief valve.
Clean the mating surfaces.
Replace the O-ring with a new one at the relief
valve, and apply a thin coat of refrigerant oal
(ND-OIL 8: P/N 38899 - PR7 - A01) before install-
ing it.
NOTE:
. To avoid contamination, do not return the oil
to the container once dispensed, and never
mix it with other refrigerant oils.
. lmmediately after using the oil, replace the
cap on the container, and seal it to avoid
moisture absorption.
. Do not spill the refrigerant oil on the car; lt
may damage the painu if the refrigerant oil
contacts the paint, wash it off immediately.
Check for leaks, and insert the cap in the top of
the valve.

A/C System Service
Leak Test
Only use 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 system.
CAUTION: Exposura to air condition ratrigerant and
lubaicant vapor or mist can irritato oyes. nose and
throat. Avoid br€athing tho sir conditionsr reftigolant
and lubricant vapor or mist.
lf accidental svstem discharge occurs, ventilate work
area before resuming service.
R-134a service equipment or vehicle air conditioner sys-
tems should not be pressure tested or leak tested with
comoressed air.
@ some mixturos ot air and R'13'la have
b.6n shown to b€ combustible at glsvated pressur€s

Additional health and satetY information may be ob-
tained from the refrigerant and lubricant manufactures'
1. Connect a R-134a retrigerant Recovery/Recycling/
Charging System to the car. as shown, following
the equipment manufacturer's instructions.
NOTE: Be sure to install the same amount of new
refrigerant oil back into the A/C system before
chargtng.
2. Open high pressure valve to charge the system to
about 98 kPa (1.0 kgf/cm', 14 psi), then close the
supply valve.
3. Check the system for leaks using a R-134a refriger-
ant leak detector with an accuracy of '!4 g {0.5 oz)
per year or better.
4. lf you find leaks that require the system to be
opened (to repair or replace houses, fittings, etc.),
recover the system according to the Recover
Procedure on page 22-22.
5. Aiter checking and repairing leaks, the system must
be evacuated (see System Evacuation gn page 22-
38).

Recommendsd Procodure:
a Use a staner svstem tester.
a Connect and operate the equipment in accordance
with the manutacturer's instructions.
a Test and troubleshoot as described.

Chock Stan€r Engag6ment:
1. Disconnect the 2-P connector (ignition coil primary
lead) from the distributor.
Press the clutch pedal allthe way in (M/T), and turn
the ignition switch to "Start". The starter should
crank the engine.
NOTE: On cars equipped with manual transmission,
the engine will not crank unless the clutch pedal is
fully depressed.
lf the staner does not crank the engine go to step 3.
Check the baftery, battery positive cable, ground,
and the wire connections for looseness and cor-
rosion,
Test again. lf the starter still does not crank the en-
gine, go to step 4.
Bvpass the ignition switch citcuit as follows {make
sure the transmission is in neutral):
Unplug the connector (BLK/WHT wire and solenoid
terminsl) trom the starter. Then connect a jumper
wire from the battery positive ( + ) terminal to the
solenoid terminal. The starter should crank the
engrne.
a lf the starter still does not crank the engine,
replace it and diagnose its internal problems.
a lf the starter cranks the engine, go to step 5.
