ENGINE AND ENGINE SYSTEMS
Exhaust system components get very hot and can cause
severe burns.
The exhaust system is installed under the frame to minimize
the transfer of noise and vibration into the operator 's
compartment.
Annoying rattles and noise vibrations in the exhaust system
are usually caused by misalignment of parts. When aligning
the system, leave all bolts and nuts loose until all parts are
properly aligned, then tighten working from top to bottom.
When installing exhaust parts, make sure there is sufficient
clearances between the hot exhaust part and parts that
would be adversely affected by heat.
When installing an exhaust system, allow for expansion
when the system is hot.
Periodic maintenance of the exhaust system is not required,
However, it is advisable to check the condition of the system
when performing other maintenance on the crane.
Check the complete exhaust system for broken, damaged,
missing or mispositioned parts, open seams, holes, loose
connections and other deterioration which could cause
exhaust fumes to seep into the operator's compartment. Any
damaged areas must be corrected.
