flywheel damper

[robeward]

what does it do?

i understand the definition of a damper but curious what exactly is going on when it applies to an inboard?

 

[Scott Danforth]

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.

When you say flywheel damper do you mean the coupler?

If he has a Volvo drive, it is indeed on the flywheel.

It's basically there to avoid vibrations.

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?

Scott u are talking about harmonic balancer right or is that really an automobile term?
