Revision C
7.8.9 EXHAUST SYSTEM
CAUTION
To avoid burns, do not touch muffler when
engine is running or before allowing sufficient
cooling time after shut-down
The exhaust system requires no regular
maintenance. but it should be inspected
periodically as follows:
a. Open engine compartment hood to highest
position.
b. Inspect the area around clamps (A) for breakage,
cracks and rust-through. In addition to excess
noise, a leaky exhaust system may allow exhaust
gases to escape to the cab.
c. Dents or crushed portions of any tubing create
exhaust flow restriction and increase back
pressure significantly.
• Even relatively small dents will cause
decreased fuel economy and increased turbo
wear.
• If dents are relatively large, increased bearing
and cylinder wear will occur due to increased
exhaust temperature.
d. The exhaust system should be secured to
eliminate vibration. The brackets (B) should fit
securely to the muffler (C) and to the engine.
IMPORTANT
Do not change muffler type, piping sizes or
exhaust configuration - these have all been
selected for some very specific, technical
reasons by the Engineer. See your
MacDon Dealer for proper replacement
parts.
