3.5.7 Viscose type vibration damper
(1) Housing
(2) Damper mass
(3) Liquid cavity
(4) Bushing
Engine has a vibration damper of "viscose type".
Inside the damper there is a housing filled with
stiff silicone oil, in which the damping substance
has very small tolerances.
NOTE: Even a small dent makes the vibration
damper inoperative. Do not remove it by turning
forcibly and be careful not to damage it when it is
loose. If you detect a dent on the outer surface, do
not re-install the damper in the engine.
NOTE: If you are making the installation mark on
the vibration damper, use an electric pen, do not
tap it.
