Rattle & Shake When Moving On

I'm restoring my R51/3 and i recall before taking it apart (I rode it for few months) , I noticed that for 3 seconds just when I was about to fully release the clutch , the back wheel and the whole back axle was shaking and rattling . After 3 seconds it was ok but it happened every time I started moving..
During my restoration I replaced :
1. The rubber disc at the driveshaft.
2. 6207 bearing .
3. New gaskets
4. New grease at pin bearing .

I attached a photo of something that bothered me .

Could these chips possibly cause these shakes? If not , what could ?

That part is way beyond worn,and ready for the bin. Check out www.Motorrad-stemler.de they have those brand new or S.Meyer or Uli's.

found it one eBay and waiting for a quote from the seller
Anyhow, do you think that this is the part that was to blame for the rattle? And if there's maybe something else that could make the rattle?
Thanks
