The damper protects the drive systems on and

after the engine from torsional vibrations by

reducing the torsional vibrations of the engine

due to the fluctuations in torque.

The power from the engine is transmitted to

coupling (3) through flywheel (7), absorbing

torsional vibrations on coupling (3). Then it is

transmitted to HST pump through boss (4).
