7) Apply the window glass sealing adhesive
2.
If you are using an air gun, air pressure should be
maintained at 147 - 294 kpa.
After drying primer completely, apply a sealing adhesive
(Sunstar #557 or equivalent) along the edge of the glass so
that the sealing adhesive has a 20 mm (0.79 in) junction a
t
middle of the vase of the glass.
Note :
Open time (1 min. or more) should be set after application
of the primer.
Bonding shall be done within 5 minutes after the sealing
adhesive has been applied.




8) Adjust the setting of the windshield glass with suction discs.
Set the windshield with sealing adhesive applied to entire
circumference in the body panel. Specifically, adjus
t
windshield support with the upper molding making contact
with the body panel, press the glass, and tighten the
windshield support.



9) Use unleaded gasoline and a soft cloth to wipe away any
excess adhesive.
Cure the bonding at a temperature of 68
- 86
F (20
-
30
C) for twenty-four hours.
Check that the windshield does not leak water.









8. Wiper Arm Assembly


Set the wiper arm/blade so that the tips of both blades
are positioned the specified value of
A and Bfrom the
upper edge of the cowl cover as shown in the figure.

A 40 mm (1.57 in)

B 52 mm (2.05 in)


Tighten the wiper arm assembly fixing nuts to the
specified torque.
Torque Nm (kgfm/lbft)

INSPECTION AND REPAIR
Make the necessary adjustments, repairs, and part replacements if excessive wear or damage is discovered during
inspection.




PRESSURE PLATE ASSEMBLY
Visually inspect the pressure plate friction surface for
excessive wear and heat cracks.
If excessive wear or deep heat cracks are present, the
pressure plate must be replaced.



Pressure Plate Warpage
Use a straight edge and a feeler gauge to measure the
pressure plate friction surface flatness in four directions.
If any of the measured values exceed the specified limit, the
pressure plate must be replaced.
Pressure Plate Warpage mm(in)
Limit
0.3 (0.012)



Clutch Cover
Visually inspect the entire clutch cover for excessive wear,
cracking , and other damage.
The clutch cover must be replaced if any of these conditions
are present.



1. Abrasion, scratches, cracks and deflection of friction face to
the disc, loose rivet and wear of ring

Grind small scratches, or replace the assembly if extreme
scratches are found.

8A-132 ELECTRICAL-BODY AND CHASSIS

Wire Harness
Do not pinch the wire harnesses between the cluster and the
meter hood during the cluster installation procedure.
Wire damage will result.


AIMING OF HEADLIGHT
Check and adjust the inflation pressures, clean the headlight,
park the vehicle on a level surface and insure that vehicle is at
curb weight.


VERTICAL ADJUSTMENT
Use a screwdriver for vertical adjustment.



HORIZONTAL ADJUSTMENT
Use a screwdriver horizontal adjustment.


Installation
To install, follow the removal steps in the reverse order.
Noting the following point:
1. After installing the headlight, be sure to adjust the headligh
t
aim.

HEADLIGHT ADJUSTMENT
Preparation
Place the vehicle with 1 person in driver seat on a level surface
and check to see if the inflation pressure of the tires is correct,
the lenses are clean, the battery is sufficiently charged, and
adjust to place vehicle by using the screen.
1. Set a vertical screen on a level surface.
2. Toward the screen
1from the bulb center mark of the
headlight, extend parallel lines to the floor. Mark point
A
and B on the screen at the intersection of parallel line and
the screen.
3. Draw vertical lines through point
A and B on the screen.

Valve Seat Insert Installation
1. Carefully place the attachment (1) (having a smaller
outside diameter than the valve seat insert) on the valve
seat insert (2).

NOTE:
The smooth side of the attachment must contact the
valve seat insert.

2. Use a bench press (3) to gradually apply pressure to the
attachment and press the valve seat insert into place.

NOTE:
Do not apply an excessive amount of pressure with
the bench press. Damage to the valve seat insert will
result.








Valve Seat Insert Correction
1. Remove the carbon from the valve seat insert surface.
2. Use a valve cutter (15
, 45
, and 75
blades) to minimize
scratches and other rough areas. This will bring the
contact width back to the standard value.
Remove only the scratches and rough areas. Do not cut
away too much. Take care not to cut away unblemished
areas of the valve seat surface.









Valve Seat Angle Degree
45
NOTE:
Use an adjustable valve cutter pilot.
Do not allow the valve cutter pilot to wobble inside the
valve guide.











3. Apply abrasive compound to the valve seat insert surface.
4. Insert the valve into the valve guide.
5. Turn the valve while tapping it to fit the valve seat insert.
6. Check that the valve contact width is correct.
7. Check that the valve seat insert surface is in contact with
the entire circumference of the valve.

POOR FUEL ECONOMY SYMPTOM
DEFINITIONS: Fuel economy, as measured by an actual road test, is noticeably lower than expected. Also, economy
is noticeably lower than it was on this vehicle at one time, as previously shown by an actual road test. (Larger than
standard tires will cause odometer readings to be incorrect, and that may cause fuel economy to appear poor when it
is actually normal.)

Engine Noisy
Abnormal engine noise often consists of various
noises originating in rotating parts, sliding parts and
other moving parts of the engine. It is, therefore,
advisable to locate the source of noise systematically.

Condition Possible cause Correction
Noise from crank journals or from
crank bearings
(Faulty crank journals and crank
bearings usually make dull noise
that becomes more evident when
accelerating) Oil clearance increased due to
worn crank journals or crank
bearings Replace crank bearings and
crankshaft or regrind crankshaft

Crankshaft out of round Replace crank bearings and
crankshaft or regrind crankshaft
and install the over size bearing
Crank bearing seized Replace crank bearings and
crankshaft or regrind crankshaft
