Having just successfully replaced my alternator damper, after starting issues, I was wondering what exactly is the purpose of this component?

Cheers,

Welcome to the forum Dennis.
It may stop the primary chain from whipping. I haven't had one apart myself so I'm guessing at this one.

 

reduce vibrations?

 

Found it! : "The starter damper is there because the crankshaft is connected to alternator shaft via chain. To have security there must be a clutch. Imagine what could happen if the alternator rotor jams for some reason - the crankshaft would be seriously injured if there would not be clutch." on another thread.

 

Good to know!
Thank you sir!
