the crank damper is mounted to the front of the engine crank shaft. it is usually a weighted ring mounted with an elastomeric member to the balanced inner ring/flange. it dampens the harmonics generated in the motor from the firing pulses.

Yeah Bruce that's it. I guess the plate is like a counter weight. The splined section is connected through those springs and they provide the damping action. Is it for going in and out of gear or a little of everything?
