Thank you Bill and Danny.
That helps.

Dear Vladan,
thx a lot. 
Unfortunately the photo is not readable (list of seals). Thus I appreciate a better resolution. Thanks for that.

I found 2 good sources of supply (in Germany/ for Europe):

https://www.kugellager-express.de/va-und-wellendichtringe (v-rings, oil seals)
https://www.hug-technik.com/shop/O-RINGE/  and https://www.hug-technik.com/shop/Simmerring/ (o-rings, oil seals)

Best regards
