PROCEDURES
Compressor Clutch(Cont'd)

• Pulley removal
Position thecenter pulleypulleronthe end ofthe drive
shaft, andremove thepulley assembly usinganycommer-
cially available pulleypuller.

To prevent thepulley groove frombeing deformed, the
puller clawsshould bepositioned ontotheedge ofthe pul-

ley assembly.

INSPECTION
Clutch disc

If the contact surface showssignsofdamage duetoexcessive
heat, theclutch discandpulley should bereplaced.

Pulley

Check theappearance ofthe pulley assembly. Ifthe contact
surface ofthe pulley shows signsofexcessive groovingdueto
slippage, boththepulley andclutch discshould bereplaced.
The contact surfaces ofthe pulley assembly shouldbecleaned
with asuitable solventbeforereinstallation.

Coil

Check coilforloose connection orcracked insulation .

INSTALLATION

• Position thefield coil.

Be sure toalign thecoil's pinwith thehole incompressor's
front head.

• Install snapring(which secures fieldcoil)byusing external
snap ringpliers.

Using theclutch wrench disctoprevent clutchdiscrotation,
tighten thebolt to12 to15 N'm (1.2to1.5 kg-m, 9to 11ft-Ib)
torque.

After tightening thebolt, check thatthepulley rotates smoothly.

• Check clearance aroundtheentire periphery ofclutch disc.

Disc-to-pulley clearance:
0.3 -0.6 mm (0.012 -0.024 in)

If the specified clearance isnot obtained, replaceadjusting
spacer andreadjust.

BREAK-IN OPERATION

When replacing compressor clutchassembly, donot forget
break-in operation, accomplished byengaging anddisengaging
the clutch aboutthirtytimes. Break-in operation raisesthelevel
of transmitted torque.

Item

OUTSIDE THEVEHICLE

The maintenance itemslistedhereshould beperformed fromtimetotime, unless oth-
erwise specified.

Tires
Check thepressure withagauge periodically whenataservice station, including
the spare, andadjust tothe specified pressureifnecessary. Checkcarefully fordamage,
cuts orexcessive wear.

Windshield wiperblades
Checkforcracks orwear ifthey donot wipe properly.

Doors andengine hood
Check thatalldoors, theengine hood,thetrunk lidand back
door operate properly. Alsoensure thatalllatches locksecurely. Lubricate hinges,
latches, rollersandlinks ifnecessary. Makesurethatthesecondary latchkeeps thehood
from opening whentheprimary latchisreleased.
When driving inareas usingroadsaltorother corrosive materials, checkforlubrication
frequently.

Tire rotation
Tiresshould berotated every
10,000
km
(6,000
miles).

INSIDE THEVEHICLE

The maintenance itemslistedhereshould bechecked onaregular basis,suchaswhen
performing periodicmaintenance, cleaningthevehicle, etc.

Lights
Makesurethattheheadlights, stoplights, taillights, turnsignal lights,andother
lights arealloperating properlyandinstalled securely. Alsocheck headlight aim.

Warning lightsandbuzzers/chimes
Makesurethatallwarning lightsandbuzzers/chimes
are operating properly.

Check forchange inthe steering conditions, suchasexcessive freeplay,
hard steering orstrange noises.

Free play: Lessthan35mm (1.38 in)
Seat belts
Check thatallparts ofthe seat beltsystem (e.g.buckles, anchors, adjusters
and retractors) operateproperly andsmoothly, andareinstalled securely. Checkthebelt
webbing forcuts, fraying, wearordamage.

UNDER THEHOOD ANDVEHICLE

The maintenance itemslisted hereshould bechecked periodically e.g.each timeyou
check theengine oilorrefuel.

Windshield washerfluid
Check thatthere isadequate fluidinthe tank.

Engine coolant level
Check thecoolant levelwhen theengine iscold.

Engine oillevel
Check thelevel afterparking thevehicle onalevel spotandturning off
the engine.

Brake andclutch fluidlevels
Makesurethatthebrake andclutch fluidlevels arebetween
the "MAX" and"MIN" linesonthe reservoir.

Battery
Checkthefluid level ineach cell.Itshould bebetween the"MAX" and"MIN"
lines.
