The viscous damper has a weight that is located
inside a fluid filled case. Inspect the damper for
evidence of fluid leaks. If a fluid leak is found,
determine the type of fluid.
Also inspect the dampers for signs of damage, or
heat discoloration.
Inspect and replace the damper for any of the
following reasons:
• The damper is dented, cracked, or leaking
• The paint on the damper is discolored from heat
• Analysis of the oil shows wear metals and
particles
• The temperature of the damper fluid is 100
degrees Celsius and above
For more information on inspection the vibration
dampers, refer to Systems Operation Testing and
Adjusting, Vibration Damper.

Engine - Clean
Personal injury or death can result from high
voltage.
Moisture can create paths of electrical
conductivity.
Make sure that the electrical system is OFF. Lock
out the starting controls and tag the controls ““DO
NOT OPERATE”” .
NOTICE
Accumulated grease and oil on an engine is a fire
hazard. Keep the engine clean. Remove debris and
fluid spills whenever a significant quantity accumu-
lates on the engine.
NOTICE
Water or condensation can cause damage to genera-
tor components. Protect all electrical components
from exposure to water.
NOTICE
Failure to protect some engine components from
washing may make your engine warranty invalid. Al-
low the engine to cool for 1 hour before washing the
engine.
Periodic cleaning of the engine is recommended. A
clean engine provides the following benefits:
• Easy detection of fluid leaks
• Maximum heat transfer characteristics
• Ease of maintenance
Note: Caution must be used to prevent electrical
components from being damaged by excessive water
when the engine is cleaned. Pressure washers and
steam cleaners should not be directed at any
electrical connectors or the junction of cables into the
rear of the connectors. Avoid electrical components
such as the alternator, the starting motors, and the
ECU.
Ensure that care is taken that the safety labels,
emission label, and any information labels are not
removed during engine cleaning.

Engine Air Cleaner Element -
Replace
NOTICE
Never run the engine without an air cleaner element
installed. Never run the engine with a damaged air
cleaner element. Do not use air cleaner elements
with damaged pleats, gaskets or seals. Dirt entering
the engine causes premature wear and damage to
engine components. Air cleaner elements help to pre-
vent airborne debris from entering the air inlet.
NOTICE
Never service the air cleaner element with the engine
running since this will allow dirt to enter the engine.
