Exhaust System Removal
Caution: Wait at least 30 minutes between the engine
being turned off and the actual removal of any component
of the exhaust system, as to avoid personnel injury due to
hot components.
1. Main muffler assembly removal
(a) First use a No. 13 wrench (open), sleeve, or ratchet
spanner to remove the connecting spring bolt between
the front flange of the main muffler assembly and the
rear flange of the sub-muffler. Then take out the gasket
between the flanges.
(b) Remove the two rubber hangers on the main muffler.
(c) Take down the main muffler assembly.
Caution: The sealing ring between the front flange of
the main muffler assembly and the rear flange of the
sub-muffler is used only for sealing. If reused, it may
cause large deformations and result in a poor sealing
effect. Accordingly, it is suggested not to use a sealing
ring repeatedly. If necessary, only one repetition should
be allowed.
Warning: While performing this kind of maintenance
work, a person should be present to support the main
muffler to avoid injury in case the muffler falls.
2. Sub-muffler assembly removal
(a) Use a No. 14 wrench (open), sleeve, or ratchet wrench
to remove the connecting bolt between the front flange
of the sub-muffler assembly and the rear flange of the
catalyst assembly.
(b) Remove the support of the sub-muffler plate bracket.
(c) Remove the two two-hole rubber hangers between the
sub-muffler and the frame.
(d) Take down the sub-muffler assembly.
Caution: The sealing ring between the front flange of
the sub-muffler and the rear flange of the catalyst as-
sembly is used only for sealing. If reused, it may cause
large deformations and result in a poor sealing effect.
Accordingly, it is suggested not to use a sealing ring
repeatedly. If necessary, only one repetition should be
allowed.
Warning: While performing this kind of maintenance
work, a person should be present to support the sub-
muffler to avoid injury in case the muffler falls.
3. Rear catalytic assembly removal
(a) Remove the connecting spring bolt between the front
flange of the sub-muffler assembly and the rear flange
of the rear catalytic assembly. Then take out the sealing
ring between the flanges.
(b) Take off the rear catalytic assembly.

4. Front exhaust pipe removal
(a) Use a No. 14 wrench (open), sleeve, or ratchet wrench
to remove the connecting nut between the front flange
of the front exhaust pipe assembly and the flange of the
exhaust manifold. Then take out the gasket between the
flanges.
(b) Carefully remove the front exhaust pipe from the
subframe.
Caution: The gasket between the front flange of the
f r o n t e x h a u s t p i p e a n d t h e f l a n g e o f t h e e x h a u s t
manifold are used only for sealing. If reused, they may
cause large deformations and result in a poor sealing
effect. Accordingly, it is suggested not to use the
sealing ring repeatedly.
Exhaust System Installation
1. The clearance between the exhaust pipe assembly and
both sides of the individual components should be no
less than 15 mm.
2. Before installing rubber hangers, coat a proper amount
of silicon oil in holes. After installation, even force
should be applied.
3. After installing the center exhaust pipe with the three-
way catalytic converter assembly, ensure the plug of
the oxygen sensor is well connected.

Before installing, check to make sure that the rigid pipe flare contact area is in good condition, the pipeline is
clean, and that there is no foreign materials.
2. Clutch Hose Installation
Check the surface of the clutch hose to make sure that there is no scuffing and that the pipeline is clean.
3. Coat grease on the U-joint of the pedal and the master cylinder.

Clutch Master Cylinder Installation
Installation of clutch system is reverse to its removal, but
since the whole clutch system uses hydraulic assistance,
make sure to air bleed it after the installation is completed.
Detailed steps as follows:
(a) Plug one end of the long transparent connection hose
(about 0.5 m long) into the bottom of bleed screw, and
the other end into a fixed container.
(b) Loosen the bleed screw via the open end of the M8,
meanwhile ask the assistant to step on the clutch pedal
repeatedly until no air bubbles can be seen in the hose.
R e m a r k : R e s i d u a l a i r i n t h e c l u t c h s y s t e m h a s b e e n
completely exhausted.
(c) Lastly, lock the bleed screw.
Caution: Refilling the brake fluid reservoir should be
performed while air bleeding the clutch.

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.
