Clutch Inspection
Check the plated parts of the pressure plate for color
changes, peeling or other damage. lf there is dam-
age, 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 noisy or has excessive play/drag.
Measure the clearance between the Dullev and thepressure plate all the way around. lf the clearance is
not within specified limits, the pressure plate must beremoved and shims added or removed as required,following the procedure on page 22-33.
Clearanca: 0.50 t 0.15 mm (0.020 r 0.006 in)
NOTE; The shims are available in three thicknesses:
0.1 mm, 0.3 mm and 0.5 mm.

5. Install in the reverse order of removal, andl
install the field coil with the wire side facing
down (see above).
clean the pulley and compressor sliding surfaceswith 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.
Relief Valve Replacement
Recover the refrigerant with Recovery/Recycling/
Charging System lsee page 22-221.
Remove the relief valve and the O-ring. Plug the
opening to keep foreign matter from entering the
system and the compressor oil from running out,
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 kgf.m,9.76lbtft)
3. Clean the mating surfaces.
4. Replace the O-ring with a new one at the relief
valve, and apply a thin coat of refrigerant oil (ND-
OIL 8: P/N 38897-PR7-A01AH or 38899-PR7-A01)
before installing it.
5. Charge the system (see page 22-39), and test itsperformance (see page 22-241.

ChargingLeak Test
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 system.
CAUTION: Exposure to air conditioner refrig6rant and
lubricant vapol or mist can irritate eyes. nose and
throat. Avoid broating the air conditione. relrigerant
and lubricant vapor o; mist.
lf accidental system 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
compressed air.
@ some mixtures of air and R-1348 have
been shown to be combustible at €levat€d pre3sures
and can rosult in fire or explosion causing iniury or
property damage. Never use compressed air to pressure
test R-134a s€rvics oquipment or vehicle air conditioner
Systems.
Additional health and safety information may be
obtained from the refrigerant and lubricant manufac-
rures.
Connect a R-134a refrigerant Recovery/Recycling/
Charging System to the vehicle, as shown in the pre-
vious column, following the equipment manufactur-
er's instructions.
NOTE: Be sure to install the same amount of new
refrigerant oil back into the A/C system before
charging.
Open high pressure valve to charge the system to
the specified capacity, then close the supply valve,
and remove the charging system couplers.
R€frigerani capacity: 700 1o g 124.7 llroz)
Check the system for leaks using a R-134a refriger-
ant leak detector with an accuracy of 14 g (0.5 oz)
per year or better.
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.
After checking and repairing leaks, the system must
be evacuated (see System Evacuation on page 22-
38).
JUse 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 system.
CAUTION: Exposure to air conditioner r€frigsrant and
lubricant vapol or mist can irritate eyos, nose and
throat. Avoid broathing the air conditioner reftigerant

lf accidental system discharge occurs, ventilate work
area before resuming service. Additional health and

Place the armature on an armature tester. Hold a
hacksaw blade on the armature core. lf the blade is
attracted to the core or vibrates while the core is
turned, the armature is shorted. Beplace the arma-
ture.

NOTE: Before starting the following checks, disconnectthe wire from terminal M, and make a connection asdescribed below using as heavy a wire as possible (prefer
ably equivalent to the wire used for the car).
Pull-in Coil Test:
Connect the battery as shown. If the starter pinion pops
out, it is working properly.
CAUTION: Do not leave the battery connectsd Jor morethan 1O seconds.
Hold-in Coil Test:
Disconnect the battery from the M terminal. lf the pin-
ion does not retract, the hold-in coil is working properly.
CAUTION: Do not leave the battery connected for more
than 10 seconds.

Retracting Test:
Disconnect the battery negative cable. lf the pinion
retracts immediately, it is working properly.
CAUTION: Do not leave the battery connected fol more
than 1O seconds.
Starter No]oad Test:
1. Clamp the starter firmly in a vise.
2. Connect the starter to the battery as shown, andconfirm that the motor starts and keeps rotating.
3 lf the electric current and motor soeed meet thespecifications when the battery voltage is at 1 1.5 V,the starter is working properly.
