GWFLORID will build 1.3L (GW413EF, GW4G13) or 1.5L (GW4G15) gasoline engines, in which the
GW4G13 and GW4G15 engines will both incorporate the newest VVT technology which meets the Euro IV
emission standards. GWFLORID features McPherson technology on its chassis system. With an ultra light
body made from structural steel and high-intensity front and rear fender impact beams as well as a collision
impact absorption system, it is able to maintain the cab's integrity and safety to greater extent. We wrote this
maintenance manual in order to meet the demand of Great Wall after-sales service technicians. This manual
mainly introduces the areas of importance in regard to maintenance and care, and removal and installation of
each system's assembly and maintenance technical parameters.
To reduce the possibility of injury or property damage, read and follow t\
he instructions carefully:
This manual is provided by the Great Wall Motor Co., Ltd, and is written for the technician use. Any
maintenance or repair without proper prior training and tools or devices may result in personal injury of the
person performing the maintenance or others in the vicinity. It is also possible that damage to the vehicle will
occur or will lead to mechanical failure during normal operation.
Correct vehicle maintenance and repair is essential for the safety of the person performing regular
maintenance as well as the vehicle itself. If there is any component that needs to be replaced, use a
component with the same serial number or a serial number specified by the Great Wall Motor Co., Ltd. Never
use any part that has not been authorized by the Great Wall Motor Co., Ltd.
Any maintenance procedure introduced in this manual is effective for maintenance and repair. Some of
these procedures need specially designed tools.
Therefore, before using any vehicle part following any maintenance procedure or working with a tool
that has not been authorized by the Great Wall Motor Co., Ltd, check to make sure that none of the above
will endanger the safety of the person performing the work or the correc\
t operation of the vehicle.
This manual includes multiple "Warnings" and "Cautions," which should be strictly followed, so as to
reduce the possibility of injury during maintenance or repair. Improper maintenance or repair of the vehicle
may cause potential safety hazards. These "Warnings" and "Cautions" are not exhaustive. It is impossible for
the Great Wall Motor Co., Ltd, to warn against all the potential dangers caused by not properly following the
instructions.
Please read carefully the "Areas of Importance" before carrying out any maintenance or repair on the
airbag system's components or its surrounding electrical components. Action contrary to any of the "Areas of
Importance" may lead to the deployment of the airbag, resulting in injur\
y or unnecessary repair of the airbag.
To avoid accidental deployment of the airbag and its resulting injury, we suggest repairing the airbag
system before other vehicle systems if the airbag and the other vehicle \
systems both need repairing.
We have received generous support and help from many professional technicians during the preparation
of this manual. We would like to express our heartfelt gratitude to all of them.
Although we have tried our best to write this manual well, we do not guarantee that the entire content
in this manual is absolutely correct. Users may not make any legal claim against the Great Wall Motor Co.,
Ltd. in regards to this manual. Any loss caused by using this manual is not our responsibility. Because of
the writer's limited experience, there are likely mistakes in this manual, therefore we welcome any user
comments, suggestions, and corrections.
Great Wall Motor Co., Ltd. reserves the final right of explanation.

General Repair Methods and Operations
1. If a jack is needed, please kindly comply to the safety procedures liste\
d below.
2. Park the vehicle on a flat surface, stablize the front and the back wheels using any fixed object or tool,
jack up the vehicle, support it with the chassis, and then start the mai\
ntenance.
3. Disconnect the battery's negative cable before maintenance, in order to reduce the possibility of
damaging and burning out the cable due to a short circuit.
4. Cover the vehicle body, seats, and floor to prevent them from being damaged and polluted.
5. Handle brake fluid and antifreeze fluid carefully, because it may damage the vehicle's surface paint
and its surroundings.
6. Using the proper tools or basic tools that have been recommended and are purchasable is very
important in guaranteeing an effective and reliable maintenance result.
7. Dispose the used dowel pins, gaskets, O-rings, oil seals, lock washers, and self-locking nuts. Prepare
new parts for installation. Normal functions are not guaranteed if these\
parts are reused.
8. Store the removed parts in order and in groups to make reassembly more c\
onvenient.
9. Store bolts and nuts separately, because their hardness levels and designs are different according to
the installation locations.
10. Clean parts before they are inspected or reassembled. In addition, parts that come in contact with
engine oil also need to be cleaned, as well as checked for blockage by u\
sing compressed air.
11. Before installation, use engine oil or grease to lubricate the rotating and sliding sides of the necessary
parts.
12. When necessary, use sealant on gaskets to avoid leakage.
13. Please carefully comply to all tightening torque specifications of b\
olts and nuts.
14. After maintenance, check to make sure whether the repairs were performed correctly and whether the
malfunctions have been fixed.
Vehicle Lifting/Lowering Procedures
When lifting the vehicle, the lifter must be placed at the indicated spots. Using these indicated spots
incorrrectly can lead to permanent deformation of the vehicle body. Many vehicle service stations
have autolifts that raise vehicles by supporting certain vehicle parts. If using other types of lifts, be
careful to prevent damages to the fuel tank, oil filler, or the base of the vehicle body.

037A Transmission’s Overall External Schematics
The 037A transmission is a step mechanical transmission with differential, two-shaft front wheel drive
application. The forward gear has adopted the inertia synchronizer gear-shifting mechanism, which offers
smooth and easy gear shifting, reduces noise dramatically, and improves the service life of the gear - important
in achieving the overall economical efficiency. Regarding its control mechanism, the set steel ball and spring
allow the shifting gear to be quick, accurate with solid handling. The 5th gear transmission is equipped with an
interlocking mechanism to prevent accidental switching to reverse, to im\
prove driving comfort and reliability.

(b) On the press, press out the lower swing arm's large
shaft sleeve with SST (Special Service Tools), and re-
place it with a new one.
(c) Check that the mounting holes of the lower swing arm's
large shaft sleeve are Φ55-0.2 -0.3, measure for inaccurate di-
mensions, replace the lower swing arm's weld assembly if
inaccurate.
(d) Before press fitting, mark the same position on the
new lower swing arm's large shaft sleeve, so as to
correspond to the mark on the lower swing arm, and
thus ensure angle alignment.
(e) On the press, use SST (Special Service Tools) to press
the new lower swing arm's large shaft sleeve into the
correct position.
5. Lower swing arm's small shaft sleeve removal, replace-
ment, and press fitting.
(a) Use a sander to smooth level the rubber flange on the
lower swing arm's small shaft sleeve.
Caution: When using the sander, be very careful not to
damage the lower swing arm.
(b) On the press, use SST (Special Service Tools) to press
out the lower swing arm's small shaft sleeve, and re-
place it with a new one.
(c) Check that the lower swing arm's small shaft sleeve's
mounting hole dimensions are Φ31+ 0 . 0 5 0.
Caution: Measure for inaccurate dimensions, replace
the lower swing arm's weld assembly if inaccurate.
