1. General
Viscous vibration dampers manufactured by Hasse & Wrede, Metaldyne Interna-
tional UK, STE Schwingungstechnik and Geislinger can be mounted at the free
end of the crankshaft and in case of RTA engines as well at the free end of the cam-
shaft.
The service life of a vibration damper is largely dependent on the speed range in
which the engine is run. Wear of the inner parts as well as changes in the silicone
oil properties can reduce the effectiveness of the damper. By periodic examination
of the silicone oil the makers of the vibration damper can draw conclusions on its
condition.
The silicone oil must be examined for the first time after about 15 000−18 000 oper-
ating hours. Future intervals for examinations depend on the result of these first
findings.
Special sample containers ’PB’ (Fig. ’B’) can be obtained from the vibration
damper makers.
Remark: Before taking a sample, or before work-
ing on a vibration damper, always follow first the in-
structions of the vibration damper manufacturer.
In casing trough 1 and casing cover 2, two oil sam-
pling holes are carefully closed and sealed with
screw plugs 3.
