Propeller shaft
The input end of the propeller shaft adopts a widely used, near constant
velocity, retractable spherical roller wheel joint. The output end adopts a
Rzeppa joint.
Air intake systemDry air filter, paper filtering element.
Exhaust system
Equipped with GW413EF engine, two grade muffler with two grade three-
way catalytic converter. Front/rear oxygen sensors.
Equipped with YC4W75-31 engine, two grade muffler with one grade three-
way catalytic converter and oxygen sensor.
Fuel supply system
Equipped with GW413EF engine. The 45L metal fuel tank includes an
electronic fuel pump and a charcoal canister. An electronic accelerator pedal
controls the fuel supply. The fuel evaporation control system controls the
charcoal canister through a solenoid valve
Equipped with the YC4W75-31 engine. High pressure electronic common-
rail fuel injection and dual fuel pipeline. The 45L metal fuel tank includes an
electronic fuel pump and a charcoal canister, electronic accelerator pedal, a
fuel line is connected with the fuel-water separator and diesel fuel filter.
Cooling system
The cooling system uses the enclosed forced water circulation cooling
system, the heat dissipating electronic fan uses a two level speed controller.
The electronic fan and overflow tank are combined in one. The radiator is
equipped with upper and lower water chamber aluminum pipe. The system
pressure is 90 kPa.

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.
