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

SERVICE ADJUSTMENT PROCEDURES -
CHECKING COMPRESSION PRESSURENOSFFAI
(1) Before checking compression, ensure that engine oil, the
starter motor, and battery are all in good condition.
(2) Start the engine and wait until engine coolant temperature
has risen to
85-95°C (185-205°F).
(3) Stop the engine and pull the spark plug cables.
(4) Remove the spark plugs.
(5) Crank the engine to remove any foreign objects in the
cylinders.Caution
Cover the spark plug holes with shop towel, etc., in
order to keep expelled foreign objects from flying out,
and keep away from the holes. When measuring
compression with water, oil, or fuel having entered the
cylinder through a crack, etc., these will come flying
out of the spark plug hole hot and fast, so be sure to
take the proper precautions.
(6) Set the compression gauge to the spark plug hole.
(7) Holding the throttle valve full open, crank the engine and
measure compression.
Limit: Min. 920
kPa (130 psi) [250-400 rpm]
(8) Perform 6 and 7 above for all the cylinders, ensuring that
compression pressure differential for each of the cylinders
/Iis within the specified limit.
__Differential limit: Max. 100
kPa (14 psi)
(9) If a cylinder’s compression or pressure differential exceeds
the limit, add a small amount of oil through the spark plug
hole and repeat steps (6)-(8).
0If the addition of oil brings compression up, it is possiblethat there is poor contact between the piston ring and
cylinder wall.
@ If not compression does not come up, valve seizure,
poor valve seating, or a compression leak from the
gasket are all possible.

. ADJUSTMENT OF TIMING BELT “B” TENSION(1) Temporarily fix the timing belt “B” tensioner such that
the center of the tensioner pulley is to the left and
above the center of the installation bolt, and temporarilyattach the tensioner pulley so that the flange is toward
the front of the engine.
(2) Holding the timing belt“B” tensioner up with your
finger in the direction of the arrow, place pressure on
the timing belt so that the tension side of the belt is
taut. Now tighten the bolt to fix the tensioner.
Caution
When tightening the bolt, ensure that the tensioner
pulley shaft does not rotate with the bolt. Allowing
it to rotate with the bolt can cause excessive
tension on the belt.(3) To ensure that the tension is correct, depress the belt
(point A) with a finger. If not, adjust.
Standard value: 5-7 mm (.20-.28 in.)
26. INSTALLATION OF FLANGEInstall the flange in correct direction as shown.
22. INSTALLATION OF TENSIONER SPRING/21. TEN-
SIONER SPACERI20. TIMING BELT TENSIONER
(1) Install the tensioner spring, tensioner spacer and timingbelt tensioner.
(2) Place the upper end of the tensioner spring against the
water pump body.

arily secure tensioner.
19. INSTALLATION OF TIMING BELT(1) Ensure that the timing marks of the camshaft sprocket,
the crankshaft sprocket, and the oil pump sprocket are
all aligned.(2) When aligning the timing mark of the oil pump
sprocket, remove the plug of the cylinder block; then
insert the shaft of a cross-tip (+) screwdriver with a
shaft diameter of 8 mm
(.31 in.) into the plug hole and
check to be sure that the screwdriver’s shaft can be
inserted at least 60 mm (2.36 in.). Do not remove the
screwdriver until the timing belt is completely attached.If the screwdriver’s shaft can be inserted only to a
depth of about 20 to 25 mm
(.79 to .98 in.) because it
contacts the silent shaft, turn the sprocket by one
rotation and align the timing mark once again; then
check again to be sure that the screwdriver’s shaft can
be inserted at least 60 mm (2.36 in.).
(3) Install timing belt. While making sure that tension side
of belt is not slackened, install timing belt onto
crankshaft sprocket, oil pump sprocket and camshaft
sprocket in that order.
Caution
If the timing belt is reused, install so that the arrow
marked on it at the time of removal is pointing in
the clockwise direction..
ADJUSTMENT OF TIMING BELT TENSION
(1) Loosen tensioner mounting nut. By so doing, tensioner
will be moved by spring and will apply tension to belt.
(2) Recheck to be sure that each sprocket’s timing mark is
correct.

camshaft sprocket.
Caution
As the purpose of this procedure is to apply the
proper amount of tension on the timing belt, be
sure not to rotate the crankshaft counterclockwise
or place pressure on the belt to check the amount of
tension.(4) Apply force on tensioner toward turning direction, (in
the direction of the arrow) such that no portion of the
belt raises out in portion A, place the belt on the
camshaft sprocket such that the belt sprocket teeth arefully engaged.
(5) Tighten the tensioner installation bolt and tensioner
spacer in that order.
Caution
If the tensioner spacer is tightened first, the ten-
sioner will rotate with it and belt tension be thrown
out of adjustment. Always tighten the bolt first.(6) Check to see that the clearance between the outside of
the belt and the cover are within the standard value by
grasping the tension side (between the camshaft
sprocket and oil pump sprocket) of the centre part of
the timing belt between the thumb and index finger.
Standard value: 12 mm (.40 in.)
