Vibration Damper
Silicone Fluid Sample
1. General
Viscous vibration dampers manufactured by Hasse & Wrede, Metaldyne International
UK, STE Schwingungstechnik and Geislinger can be installed at the free end of the
crankshaft.
The service life of a vibration damper is related to the speed range in which the
engine operates.
The effect of the vibration damper can decrease when changes to the properties of
the silicone oil occur, and when the internal parts become worn.
Initially, the silicone oil must be examined between approximately 15000 operation
hours and 18000 operation hours. Regular examinations of the silicone oil will show
the manufacturers the condition of the vibration damper. Subsequent examinations
are related to the results of the initial examinations.
Special sample containers are available from the vibration damper manufacturer.

Preparation
WARNING
Injury Hazard: Before you
operate the turning gear,
make sure that no
personnel are near the
flywheel, or in the engine.
Note: Read the instructions in the
manufacturer’s documentation
before you do the procedure that
follows.
1) Remove the casing from the vibration
damper (1, Fig. 1 )
2) Operate the turning gear to move the
crankshaft (1) until a screw plug (2) is
horizontally opposite the other screw
plug. If this is not possible, a vertically
opposite position is satisfactory.
3) Carefully clean the area around the
screw plugs (2).
4) Leave the vibration damper (1) in
position for a minimum of two hours.
Note: The same conditions apply for a
vibration damper that is removed
from the engine.
5) Use applicable tools to remove the
sealing material from the screw
plugs (2).
Note: When you do step 6 ), make sure
that the screw plug (2) continues
to makes a seal.
6) Carefully loosen the screw plug (2).
