and vibration into the operator’s cab. The tail pipe directs
exhaust fumes to the right side of the vehicle, away from
the cab.
Annoying rattles and noise vibrations in the exhaust
system are usually caused by misalignment of parts.
When aligning the system, leave all capscrews and nuts
slightly loose until all parts are properly aligned, then
tighten all fasteners working from the front of the system
to the rear.
When replacing the muffler, also replace the tail pipe.
Before assembling components, use exhaust system
sealer at all slip joint connections.
When installing exhaust system components, allow
sufficient clearance between the components and other
vehicle pipes, hoses and wiring that could be adversely
affected by excessive heat.
When installing an exhaust system, provide for parts
expansion when the system is hot.
Whenever performing service on the vehicle, check the
condition of the exhaust system. Check the entire exhaust
system for broken, damaged, missing or improperly
aligned parts, open seams, holes, loose connections and
other deterioration which could permit exhaust fumes to
seep into the operator’s cab. Correct any damaged areas
immediately.
