Inspecting Exhaust System
The exhaust system requires no regular maintenance, but it should be inspected periodically.
CAUTION
The engine exhaust stack may be hot. To avoid burns, do NOT touch the exhaust canister while the engine is running.
Allow the exhaust stack to cool before attempting to service it.

Figure 5.114: Exhaust System
1.
Open the hood to its highest position. For instructions,
refer to
.
2.
Inspect the area around clamps (A) for breakage, cracks,
and rust-through. In addition to being noisy, a leaky exhaust
system may allow exhaust gases to escape to the cab,
which presents an air quality hazard for the Operator.
3.
Check the exhaust tubing for dents or crushed areas. Dents
or crushed portions of any tubing create exhaust flow
restriction and increase back pressure. Even relatively small
dents will cause decreased fuel economy and increased
wear on the turbocharger. If the dents are relatively large,
increased bearing and cylinder wear will occur due to
increased exhaust temperatures.
4.
Ensure that the exhaust system is properly secured.
Brackets (B) should fit securely to muffler (C) and to the
engine.
IMPORTANT:
Do
NOT
change the muffler type, piping sizes, or the
exhaust configuration. See your Dealer for any needed
replacement parts.
