Chery QQ Service Manual Chassis System

Steps for installation:

1.Do the installation by referring to the
dismounting steps.

2.Points of attention:

①. In the screw tightening process, the fastening

bolts controlled by torque + corner tightening
submission limits should be replaced after each
action of loosening.

② .The screws should be tightened to the

specified torques after the installation.

（III）Inspections

、Checking the dampener

Check to see if there is any oil leakage on the
dampener. If any, replace the dampener. Check
the dampening force of the dampener. If not
qualified, replace the dampener.
Check to see if the thrust bearing is excessively
worn, has any abnormal operational noise or is
jammed one way or the other. Check to see if the
lower stand of the spring has any cracks or
deformation. Check to see if the spacing block is
damaged. Check to see if the suspension reset
spring spacing washer is worn, cracked or
deformed. If so, replace the defective parts.

Attention: When disposing the dampener, please
follow the procedures described below.

、Disposal of the front dampener

（ 1 ） Stretch the dampener rod as much as

possible.

（2）Drill hole to discharge the air inside the

dampener cylinder.. Drill a hole on the cylinder

body as shown in the figure to discharge the air
inside.

Attention: The discharged air is harmless. But
iron dusts may fly all around when the hole is
drilled.

(IV)Dismounting and installation of

absorption supporting columns, column

parts and/or springs

1. If the installation fixtures are unable to be
fastened onto the operation platform, they can be
fastened in the bench vise.
2. Install a pair of jaws with diameter matching
that of the springs onto the spring compressor.

Removal

1. Loosen the spring compressor and place the
jaws
between the spring tops and bottoms (as shown
by
the arrow).

2. Press the spring till it is separated from the
upper

and lower spring stands.

3. Use the ratchet wrench (as shown in the
Figure)
to dismount the absorber supporting column stand
restriction device and the washer from the piston
connecting rod.

4. Remove the upper spring stand with absorption
block.

5. Remove the spring compressor with the spring
and the dustproof cover.

6. Dismount the baffle block.

7. Check the dismounted parts and components
for the extent of tears and wears.

）The baffle block

）The dustproof cover

3 ) The absorption block

）The absorber supporting column stand

）The upper spring stand with bearing and

restriction device

8. In the case that the used absorber needs to be

replaced, remove the absorber and then dismount

the lower wheel speed sensor wire bundle frame
from the used absorber and install it on the new

absorber (if there is no wheel speed sensor wire
bundle frame, the absorber can be replaced
directly).

Steps of installation:

1. Install the new absorber in the installation
fixture.

2. If the used spring needs to be replaced, loosen
the spring and then take the used spring out from

3. Insert the new spring into the spring
compressor

with a ring being left for the upper

section and one and a half rings being left for the
lower section.

4. Press the spring to make the spacing

between

the two jaws

≤120 mm.

5. Make sure the position of the baffle

block restriction device (1).

6. Install the baffle block and pull the

piston rod to the bottom.

7. Place the spring onto the spring stand.
Cautions:
The end of the spring must be within the position
restriction hole (as shown by the arrow).
8. Install the upper spring stand with absorption
block so as to make the punched hole have a 180
degree bias from the lower spring supporting
column position(as shown by the arrow).

）Remove the balanced beam and rubber sleeve

9. Install the separation sheath bearing and

assembly.

the positioning device.

Attention: When removing the balanced beam,

10. Make use of new nuts for tightening against
looseness.
11. Tighten the new screw nuts.
Cautions:

） Remove the joining bolt for the steering
