1．Adjustment of .4-Wheel Alignment
Test and adjust the front wheel alignment value and adjust the toe on the 4-Wheel Alignment meter.
a. Adjustment of kingpin castor: The standard value is 3°30′±30′(adjust the difference of left and right kingpin
castor to within 30′);
b. Adjustment of toe: The toe with standard value of 0～2mm is adjusted by rotating the steering cross rod. When adjust
the toe, it should rotate the cross brace in left and right side evenly. Tighten the lock nut after adjustment, the torque is
55 - 65N·m.
c. Centering and fix of steering wheel: according to the display of the alignment gauge, turn the front wheel to right
ahead, after removing the steering wheel without changing the position of steering lever, mount the steering wheel
with center aligned, the radials of the steering wheel shall be in the bilateral symmetry position, and the symbol of
Great wall on the steering wheel shall be in the confrontation position of the driver, tighten the nut, with a tightening
torque of 25 - 35N·m.
Left wheel left steering: 32, right wheel left steering:28;
Left wheel right steering:
28, right wheel right steering: 32;
b. Under the light condition of the car, the height between the center of front axis fixed bolt of the lower suspension arm to the
ground is 295
1mm, if the dimension is not within this scope, reach it through adjusting the torsion bar adjustment arm
bolt;
c. The reference dimension of the height of the car is : the left and right deviation is less than 10mm;
3. Checking the free gap of steering wheel:
Turn the orientation of the car to front, stop the engine, exert a force of about 4.9N on the steering wheel along the circumferential
direction to make the it turning to the left, there is resistance force, stop turning when the resistance force is growing; then turn
the steering wheel to the right, stop turning when the resistance force is felt to be growing; the radian value that the external edge
of steering wheel runs is the free gap of the steering wheel, its standard value shall be less than or equal to 20
, and the corner
from the central position to the left or right shall be no larger than 10.

Clutch-6
Clutch
4. Disassembly procedure:
a. Clutch cover assembly, clutch disc assembly
b. Profile spring, throwout bearing assembly
c. Dustproof cover, separation rocker arm assembly
d. Separation rocker arm ball support
Warning: When maintaining the clutch assembly, it is now
allowed to use the sand mill or dry brush and compressed air for
cleaning, lest there is powder (use wet cloth). The clutch disc
has the “asbestos fiber”, if there is powder scrap during
maintaining, the asbestos fiber in the powder scrap will floats in
the air, when human inhales the air containing the asbestos
fiber, it will cause great damage to human health.
Removal of clutch assembly
1.Remove the transmission
Remarks: Do not dry the transmission oil.
2.Remove the clutch cover and clutch disc
a. Make the alignment mark on the clutch cover and flywheel
b. Remove the fixed bolt gradually, until release the tension of spring
c. Remove the fixed bolt, pull out the clutch cover and clutch disc.
3. Remove the bearing and separation fork form the transmission
a. Remove the clip and pull out the bearing .
b. Remove the separation rocker arm assembly and leather cup.
