SERVICE ADJUSTMENT PROCEDURES
CLUTCH PEDAL INSPECTION AND ADJUSTMY’,
1.Measure the clutch pedal height (from the face of the pedalpad to the
firewall) and the clutch pedal clevis pin play
(measured at the face of the pedal pad.)
Standard value (A): 176.0-181.0 mm (6.93-7.13 in.)
Standard value (B): l-3 mm (.04-.12 in.)
2.If either the clutch pedal height or the clutch pedal clevis
pin play are not within the standard value range, adjust as
follows
:(1) For vehicles without auto-cruise control system, turn
and adjust the bolt so that the pedal height is the
standard value, and then secure by tightening the lock
nut.Vehicles with auto-cruise control system, disconnect
the clutch switch connector and turn the switch for
standard clutch pedal height. Then lock with the lock
nut.
NOTE
When the pedal height is lower than the standard value,
loosen the bolt or clutch switch, and then turn the pushrod to make the adjustment. After making the adjust-
ment, tighten the bolt or clutch switch to reach the
pedal stopper, and then lock with the lock nut.
(2) Turn the push rod to adjust the clutch pedal clevis pin
play to agree with the standard value and then secure
the push rod with the lock nut.
CautionWhen adjusting the
pedal height or the clutch pedal
clevis pin play, be careful not to push the push rodtoward the master
cylinder.3. Check to be sure that the interlock switch is as shown in
the illustration when the clutch pedal is depressed its full
stroke
[151 mm (6.0 in.)]. If necessary, loosen the lock nut
and adjust.
4.After completing the adjustments, confirm that the clutch
pedal free play (measured at the face of the pedal pad)
and the distance between the clutch pedal (the face of the
pedal pad) and the
firewall when the clutch is disengaged
are within the standard value ranges.
Standard value (C):6-13 mm (.24-.51 in.)
Standard value (D):55 mm (2.2 in.) or more

NO6OSAH
1. REMOVAL OF CLUTCH COVER ASSEMBLY/P.
CLUTCH DISCDiagonally loosen bolts which attach clutch cover to
flywheel. Back off bolts in succession, one or two turns at atime, to avoid bending cover flange.
Caution
DO NOT clean clutch disc or release bearing with
cleaning solvent.
INSPECTIONNlNGCAB
CLUTCH COVER ASSEMBLYl Check the diaphragm spring end for wear and uneven
height.
Replace
If wear is evident or height difference exceeds the
limit.Limit
: 0.5 mm (.02 in.)l
Check the pressure plate surface for wear, cracks and color
change.lCheck the strap plate rivets for looseness and replace the
clutch cover assembly if loose.
CLUTCH DISCl
Check the facing for loose rivets, uneven contact, deteriora-tion due to seizure,
adhesron of oil or grease and replace
the clutch disc if defective.
l
Measure the rivet sink and replace the clutch disc if it is outof specification.Limit
: 0.3 mm (.012 in.)l
Check for torsion spring play and damage and if defective,replace the clutch disc.
l Combine the clutch disc with the input shaft and check
sliding condition and check for play in the rotating direction.If it does not slide smoothly, check after cleaning and
reassembling. If the play IS excessive, replace the clutch
drsc and/or the input shaft.
CLUTCH RELEASE BEARING
Caution
The release bearing is packed with grease, so don’t use
cleaning oil, etc. to clean it.l Check for
beanng heat damage, other damage, abnormal
noise and/or improper rotation. Also check whether or not
there IS wear at the point of contact with the diaphragm
spring.lIf there is abnormal wear at the pornt of contact with the
release fork, replace the bearing.
RELEASE FORKlIf there is abnormal wear at the
pornt of contact with the
bearing, replace the release fork.

6. INSTALLATION OF THERMOSTAT
Install the thermostat so that the flange fits perfectly to the
recessed seat of the thermostat or thermostat housing.
2.CONNECTION OF RADIATOR UPPER HOSEAlign the mating marks on the radiator hose and hose
clamp and then connect them; then, applying force in the
direction indicated by the arrow in the illustration, seat the
clamp to the trace marks of the previous connection.
Caution
Be sure to install the hose clamps at the trace marks ofthe
previous connection.
