Crankshaft Vibration Damper - Inspect

Pressurized System: Hot coolant can cause seri-
ous burns. To open the cooling system filler cap,
stop the engine and wait until the cooling system
components are cool. Loosen the cooling system
pressure cap slowly in order to relieve the pres-
sure.
NOTICE
When any servicing or repair of the engine cooling
system is performed the procedure must be performed
with the engine on level ground. This will allow you to
accurately check the coolant level. This will also help
in avoiding the risk of introducing an air lock into the
coolant system.
1. Slowly loosen the cooling system filler cap in
order to relieve the pressure. Remove the cooling
system filler cap.
Note: Always discard drained fluids according to
local regulations.
2. If necessary, drain some coolant from the cooling
system into a suitable container in order to allow
space for the extra SCA.
3. Add the correct amount of SCA. Refer to the
Operation and Maintenance Manual, "Refill
Capacities and Recommendations" for more
information on SCA requirements.
4. Clean the cooling system filler cap and inspect the
gasket. If the gasket is damaged, discard the old
filler cap and install a new filler cap. If the gasket
is not damaged, use a suitable pressurizing pump
in order to pressure test the filler cap. The correct
pressure is stamped on the face of the filler cap. If
the filler cap does not retain the correct pressure,
install a new filler cap.

Typical example
Damage to the crankshaft vibration damper or failure
of the crankshaft vibration damper can increase
torsional vibrations. The torsional vibration can result
in damage to the crankshaft and to other engine
components. A deteriorating damper can cause
excessive gear train noise at variable points in the
speed range.
Check the damper for damage and runout. For more
information refer to System Operation Testing and
Adjusting, "Vibration Damper - Check".
