If there is no vibration from the engine and the crankshaft doesn't break then it is doing its job. Every piece of metal vibrates at a certain frequency. Hang up a crankshaft, tap with a hammer and it will ring like a bell. If the engine speed coincides with the frequency of the vibration the metal can fatigue and crack after a while. The vibration dampener prevents this from happening.

In your engine this speed will be quite high but within the engine's capability probably around 4000 - 5000 RPM. A speed you won't normally drive at today.
