The harmonic damper on
the front of your crankshaft is/was there for a reason. Like the
shock absorbers on your cars suspension, it reduces the
vibration after you hit a bump in the road. Only, in the
crankshaft the bump in the road is replaced by the power strokes
of your engine.
If you took your shock
absorbers (dampers) off the car, then every time you hit a bump
the wheel would bounce up and down for a long time afterwards.
Similarly, in the engine, the crankshaft flexing between big-end
journal and the adjacent main bearing journal is damped after a
power stroke with a damper. Without a damper the flexing is
exaggerated and fatigue cracking ensues !!!
So
Get a Damper!!!!
The trouble is that
the harmonic damper is inherently heavy, it is also specifically
“tuned” to the rotating masses of the particular engine and it’s
drivetrain.
Any deviation from
that, eg; lightening flywheels, clutches, engine swops etc, etc.
will require a change to the inertia mass on the damper. This is
hard maths and gets expensive. Alternatively, the “Rattler”
works on a totally different principle. It is generic by design
to specific engine types eg; V6, V8, 4cyl- inline, 6cyl- inline
etc.
The “Rattler” works by
opposing the tortional forces created in the crankshaft by the
power strokes. It has a number of rollers allowed to oscillate
or shuttle within pockets, causing a counteractive force to
those damaging the crank.
There is a different
model of “Rattler” for each engine type, but it is not
‘specific’ to a particular make of engine. ie; a 90 degree V8
engine has the same model of “Rattler”, regardless of whether it
is a Ford, GM or Aston !
The technology is not
new, it’s heritage lies within aerospace, where it was widely
used on piston engined aircraft.
TCI
Automotive
have been
manufacturing the “Rattler” for a wide number of American
derived car engines, Vibration Free are providing the
“Rattler” to the European derived car engines.
Light weight alloy
versions are available to the racing engine users as no inertia
rings are required.

They are not expensive, broken
cranks are!!!!!!!
