Overview of the entire car-5
The friction, disc, single-diaphragm spring clutch, hydraulic control mechanism. The external diameter of friction disc D=225mm,
internal diameter d=150mm, material is F810.
Adjustment of clutch pedal:
1. Measure the height of clutch pedal (from pedal pad surface to floor) and free stroke of clutch pedal (fork bar pin clearance).
Standard height of clutch pedal: flush with the brake pedal, free stroke of clutch pedal is 5-15mm;
2. Readjust the free stroke of pedal after adjust the height of pedal; rotate the push bar to the standard value, then fix the bolt
and nut;
3. If the free stroke of clutch pedal is not within standard value, it should rotate the adjusting bolt to standard value, then fix
the bolt and nut. Do not move the push bar to main cylinder when adjust the free stroke of pedal;
4. If the free stroke of clutch pedal and clearance between the clutch pedal and floor when the clutch is disengaged de not
consist with the standard, this may by caused by the air in hydraulic system and failure of main cylinder or clutch. It can
discharge the air of system or dissemble and inspect the main cylinder or clutch.

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.

Brake system
The front wheel brake is ventilation coil type, the rear wheel brake is disk and drum type. The service brake type is that the double-
loop vacuum assist hydraulic brake is applied on the front and rear disc brake. The parking brake is mechanical dragline acting on the
drum brake of the rear wheel.
The free stroke of brake pedal is 20mm
30mm, and the operating stroke of the pedal is 120mm. The operating stroke of the brake
handle is 17
(3 teeth)30(8 teeth).
1. The adjustment of brake pedal
Measure the operating stroke of the brake pedal, the standard value is 120mm. When the eighth is no in compliance with the
requirement, make adjustment according to the following procedures:
a. Separate the brake lamp switch wire connector, loosen the blocking nut, and turn the brake lamp switch to the position that the
stopper is not touched;
b. Unscrew the blocking nut of the operation connecting rod, use the thinnose pliers to turn the operation connecting rod, adjust
the brake pedal height to standard value, after reaching the standard value, tighten the lock nut;
c. Turn the brake lamp switch to the position that the stopper of brake pedal is just touched, continue the turning for 1/2
1 circle,
and tighten the blocking nut;
d. Connect the brake lamp switch wire connector;
e. The brake lamp should not be light when the brake pedal is in release status.
2. Standard value of brake pedal free stroke: 20-30 mm
a. Under the stopping status of the engine, step on the brake pedal for 2
3 times, clear the influence of brake assistor, then use
hand to push the brake pedal to the position that there is resistance, measure the amount of movement (free stroke). It shall
be in compliance with the regulation of standard value;
b. If the gap is less than the regulation value, check to see whether the gap between the carrier rod of brake lamp switch and the
brake pedal is in compliance with the regulation. If this gap is exceeding the regulation, it means that the gap between the drive
rod clevis pin and the brake pedal arm is exceeding the regulated value.
3. Start the engine, step down the brake pedal with a force of about 700N,ehck the main brake pump, whether there is oil
leakage on the connection positions of the brake pipeline. If there is, maintain it.
4. Operating status test of brake assistor
Conduct the operation status test of the brake assistor according to the following methods:
a. Start the engine, stop if after operating for 1
2 minutes. Step on the brake pedal for several times with normal force. Expect
that the pedal can be fully stepped down a the first stepping, the height of the brake pedal shall be raised on and on with the
stepping, thus means that the brake assistor operates normally, if the height of the pedal is not changed, it means that the brake
assistor is damaged;
b. Under the stopping status of the engine, step on the brake pedal for several times, confirms that the height of brake pedal is
elevated on and on, under the status that the brake pedal is stepped down, start the engine. At this time, the brake pedal will
move down a bit, it means that the brake assistor is working normally. If the brake pedal is moving upwards, it means that the
brake assistor is damaged;
c. Under the operation status of the engine, step down the brake pedal to stop the operation of the engine. AT this time, the there
shall be no change of the height of brake pedal within 30 seconds, it means that the brake assistor is working normally. If the
brake pedal is moving upwards, it means that the brake pedal assistor is damaged.
5. Adjustment of the parking brake system:
a.For positioning, pull the brake bar to the limit position for over 3 times, use a force of about 400N to pull the brake parking
lever, count the number of knocking teeth. The standard value of stroke of parking brake : 17
(3 teeth) 30(8 teeth);
b.If the stroke of brake parking lever is too big and not in compliance with the requirement, adjust it with the following methods:
Loosen the brake parking lever, unscrew the adjusting nut.
Remove the adjuster hole cap from the brake assembly, use screwdriver to turn the adjustor in the arrow direction to the limit
that the brake drum cannot turn.
Rotate 5 teeth in the counter arrow direction.
Rotate the adjusting nut, adjust the brake parking lever stroke to the standard value.
c. If the stroke is less than the standard value, unscrew the adjusting nut to make it reach the standard value.
d. Check to see whether the adjusting nut and the rod are loosened, whether the adjusting nut is fixed in the fixed seat.
e. After adjustment, jack up the rear part of the car. Loosen the brake parking lever, the brake disc shall not be dragged when
checking the rear wheel.
f. The breaking in of the parking brake: use the force of about 200-250N to pull the brake parking lever,drive the car for about
400m with a speed of about 60km/h, repeat for 2-3 times, then test on the slope of 30%, the car shall be able to be parked.
