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.
