maintenance GREAT WALL HOVER 2006 Service Repair Manual

Preface
Since the Great Wall Hover is put into the market, it has won the favor from the customers for its
elegant appearance, excellent performance&price ratio,concept of double area and eternal safety.The car is
furnished with Mitsubishi 4G64 engine.It has both the type of five shifts manual transmission and the type of
automatic transmission as an option. At the same time, there are also options of ABS and safety airbag, etc.
Before of its complex structure, high technical intervention and difficulty of maintenance, its maintenance
needs the reference of related documents. Upon the request of the after-sale maintenance technical personnel
of Great Wall, we have prepared this Hover Maintenance Manual. The manual is oriented towards the after-
sale maintenance technical personnel of the Great Wall, and mainly introduces the disassembly of the various
systems of Hover (refer to the maintenance manual of motor for the introduction of the motor), the
troubleshooting, matters needing attention for maintenance and the related technical parameters.
During the preparation of this book, a lot of professional personnel have given support and help, here we
would like to express our sincere thanks.
Though we have made efforts to prepare this manual earnestly, we cannot guarantee that the content in
the manual is totally accurate and without error. The user cannot raise improper request to the Great Wall

e. Mount the cable terminal onto the binding post of the loosened nut,
then tighten the nut. Does not use hammer to knock at the terminal
onto the post.
f. Do remember to check whether the positive pole (
) terminal cap
is in its position.
4. Check all the soft tubes and wire terminal, check to see whether
they are connected correctly and firmly.
5. Used component which can not be used any more.
a. The following spare parts needs always to be renewed: split pin,
seal gasket, O ring and oil seal, etc.
b. For the used component which can not be used any more, it is
indicated by symbol “¦” in elements diagram.
6. Precoated component
The precoated component includes the bolt and nut which is precoated
with the locking sealant in factory.
a. If the precoated component is tightened, loosed or moved by any
reason, it must be recoated with the specified sealant.
b. Coating procedure of precoated component
Remove the old sealant from the screw of component by washing.
Dry it by compressed air.
Coat the screw of components with the specified locking sealant.
c. The precoated component is indicated by symbol “?” in elements
diagram.
7. It can use the sealant or seal ring to prevent the leakage if
necessary.
8. Abide by all specifications for bolt torque strictly. It should use
the torque wrench.
Comprehensive maintenance instruction
1. Use the protection plate, seat and floor covering cloth to make
the car clean and prevent it from being damaged.
2. During the disassembling, place the components in order for the
convenience of assembly.
Observe the following issues:
a. Before conducting the electrical work, remove the negative pole of
the cable from the accumulator terminal.
b. When it is necessary to remove the accumulator for checking or
maintenance, the cable shall be removed from the negative pole
(
) connected to the car body.
c. In order to avoid the damage of accumulator terminal, when removing
the cable, loosen the terminal nut, then pull the cable upwards
vertically, do not twist or pry it.
d. Please use cleaning cloth to clean the accumulator terminal. Do not
use file or other similar tools, which may scuff them.

9. Determine the necessity of using special maintenance tools and
special maintenance material according to the practical situation
of maintenance. Use them on the necessary position, and go on
with the maintenance according to proper procedures.
10. To replace the fuse, check to see whether the rated current of
new fuse is correct. Do not exceed the rated current of the fuse,
or do not use the fuse with low rated current.
11. When jacking up or supporting the car, lift or support the car on
proper position with care.
a. If only jacking up the car in the front part or rear part, choke up the
wheel to ensure the safety.
b. After the car is jacked up, use frame to support it. It is dangerous to
conduct maintenance on the car that is only jacked up with one
screw jack, even for the minor maintenance that can be finished
quickly.
12. Paying attention to the following matters to avoid the damage
of components:
a. If it is not absolutely necessary, do not open the housing of the
ECU and the computers (if the IC terminals are touched, the IC
may have electrostatic damage).
b. When removing the vacuum tube, pull the end of the tube instead of
the central part of the tube.
c. When pulling the wire terminal, pull the terminal itself instead of
the wire.
d. Take care to not make the electrical components fallen, such as the
sensor or relay.
If they fall to the hard ground, they must be replaced.
e. Never use the striking wrench to remove or install the electric
thermostat or thermostat sensor.
f. When checking the conducting state of the wire connector, insert
the multimeter with care, do not bend the terminal.
g. When using the vacuum meter, do not insert the soft tube onto large
connector. Use the stepped terminal. Once the soft tube is swelled
and tightened, there may be leakage.

Inspection of SC5M2D-C transmission:
1.Check the oil level of transmission:
Screw off the oil discharge plug of the transmission; discharge all lubri-
cate oil; screw on the oil discharge plug to the specified torque; the
torque is: 30
35Nm. Fill the transmission with the transmission
oil through the oil filling port, oil number is hyperbolic gear oil SAE80W/
90, which meet API GL-4, oil capacity are 2.2L. Tighten the oil-filling
plug to the specified torque of 30
35Nm. (for area with high or
low temperature refer to the maintenance specification)
2. Replacement of oil seal of rear hosing:
The replacement of the oil seal of rear housing is shown in figure.
Disconnect the drive shaft from the rear housing; remove the oil seal
by the flat screwdriver, then use the special tools to knock the rear
housing oil seal in the rear housing. It should pay attention to the
installation of oil seal, shown as figure. Coat the lip of oil seal with the
specified transmission oil.
3. Removal, installation and inspection of transmission
The preoperation before removal and after installation of transmission
is: Remove and install the manipulator cover assembly, drain and fill
the transmission oil accordance with the regulation; after remove and
install the drive shaft. Separate each plug-in part from the vehicle
transmission .

Inspection of manipulator cover assembly
Shown as figure, remove the adhesive on the surface before installation,
use the screwdriver( M8
1.25) to clean the adhesive in the screw
hole; coat the installed part of bolt screw with the specified screw
adhesive. Firstly, install two positioning bolts A, then install other
two bolt A and bolt C respectively. The tightening torque of all bolts is
15
22Nm.

2.Replacement of oil-seal of transfer case
The replacement of transfer case oil seal is shown as figure. Disconnect
the drive shaft from the transfer case, use the flat head screwer to
remove the oil seal
Caution: Do not damage the housing hole during the disassembly.
Then use the special tools to knock the transfer case oil seal into
the transfer case. It should pay attention to the installation dire
tion of oil seal. The oil seal is flush with the port of transfer case.
Shown as figure. Coat the lip of oil seal with the specified general
synthetic gear oil.
3. Disassembly and check of transmission
The preoperation before the removal and after installation of
transmission is : When remove and install the manipulator cover
assembly, drain and fill with the specified transmission and transfer
case lubrication oil. When remove and install the front and rear drive
shaft, separate each plug-in part of transmission from the vehicle.
Inspection of manipulator cover assembly:
The bolt dimension is different for different installation position. Do not
confuse it during the installation. It should install the fixing bolt A firstly.
The tightening torque of bolt A and B bolt is 15
22Nm.
