/1), threads and screw head rests with Molykote paste “G-Rapid Plus” and
tighten with a pre-torque of
M = 100 Nm + 90° angle of rotation.
The vibration damper is connected to the lube oil system of the engine.
Free passage of oil bores (2) must be ensured for the proper functioning of the damper!
If running of the engine becomes unbalanced at certain speeds, the cause can be a defecti-
ve damper. In order to prevent further damage, avoid critical speed range and determine
defect as soon as possible by torsional vibration measurement.
Sequence of operations:
1.
Disassmbly
1.1
Remove pump carrier plate (3).
1.2
Mark two-piece stop disk (4), loosen screws (5), remove stop disk. If necessary, push off

1.3
Mark position of flywheel rim (7) to carrier (8).
1.4
Pull out spring assemblies (9) with a wire hook.
1.4.1
Inspect stop surfaces of the spring assemblies for wear.
Smooth slight burr with soft emery paper. Replace spring assembly (9) in case of deeper
grooves since there is a danger of the spring leaf ends snap getting caught in the grooves
and breaking during further operation.
