3.9 Exhaust system
The exhaust system must not be modified.
3.9.1
Clearance between exhaust system parts
and other parts
• The exhaust pipe and exhaust gas purification
devices (BlueTec
®
system) become so hot that if
they are too close to or interfere with other chassis
parts, a serious accident like fire or damage by
melting could occur. Malfunction is also a possible
consequence. Secure sufficient clearance in
accordance with the standards
컄 page 120. If this
is impracticable, provide a heat shield plate to
ensure safety.
• Do not install the tail pipe under the fuel pipe, fuel
hose joint or fuel filter drain plug.
Wooden and rubber body parts should be more
than 100 mm (3.94 in.) apart from the diesel
particulate filter (DPF) integrated muffler, SCR
muffler and exhaust pipe. If this is impracticable,
provide a heat shielding plate against to ensure
safety.
3.9.2
Exhaust gas purification devices
(BlueTec
®
system) and sensors
• Exhaust gas purification devices (BlueTec
®
system) may be damaged by tool or equipment
impact, or if dropped. When mounting, handle
them with sufficient care.
• To prevent the exhaust gas purification devices
(BlueTec
®
system) and engine proper from being
adversely affected, do not relocate the exhaust gas
purification devices (BlueTec
®
system), exhaust
temperature senor, differential pressure sensor,
lambda sensor or NOx sensor.
If temporary removal of these parts becomes
inevitable during mounting, be sure to reinstall
these parts in the original places. Connect the
pressure sensor hose properly, not in reverse, too
loose nor too tightly. Also, securely clip hose joints
and confirm that there are no exhaust gas leaks.
• Exhaust gas purification devices and sensors are
periodically removed for maintenance. Install any
nearby equipment so that removal and
reinstallation work can be carried out without any
problems.
!
The original exhaust system mounting, meaning the
bracket components including frame-mounted
castings, may not be modified. Modifications can
lead to damage to the exhaust system.

Risk of accident and injury
The tail pipe of a DPF-equipped vehicle can become
considerably hotter than that of a conventional
vehicle during automatic regeneration. Provide
sufficient clearance between the tail pipe and other
parts.
