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

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.

2.Installtion of clutch cover
a. Align the matching mark of clutch shell with that of flywheel .
b. Tighten the bolt evenly. Exert force along the edge of the clutch
cover repeatedly until binding tightly. Tighten the bolt.
Tightening force: 19N

Remarks: First tighten the upper most bolt of the 3 bolts
near thelocation pin.
3. Check the end surface runout of diaphragm spring clutch finger.
Use the special tools to check the alignment of diaphragm spring.
Maximum displacement: 0.5mm
If the displacement is greater than the specified value, use the special
tools to adjust the face runout amount of the diaphragm spring clutch
finger.
4. Coat the following components with the molybdenum disulfide
lithium base grease (NLGI NO.2) or multi-purpose grease :
contacting point of separation rocker arm assembly and bearing
bush
contacting point of separation rocker arm assembly and subcylinder
push bar
separation rocker arm assembly supporting point
gear box 1st axle spline
5. Install the leather cup, separation rocker arm assembly, clutch
cover assembly and throwout bearing in the transmission.
6. Install the transmission
matching mark
