Chain doesn't stay properly on teeth on the smallest sprocket. I think replacing only chain wouldn't be good idea?
I would like to use as similar parts as possible, that's why I asked about that UG-marking. If I change it to Hyperglide, can I use same/same kind of axle or does it need different axle? No need to replace friction shifter and rear derailleur with Hyperglide?
The old axle had scratches, how I know it should be replaced?
What is your native language? Maybe we have a member who speaks this and can help with translation?
If the chain is jumping off towards the outside on the small sprocket, the High Limit screw might need adjusting. Check to see if the derailleur jockey wheel is further out then the small sprocket. Tighten the screw to move the jockey wheel towards the smallest sprocket until it sits right below it.
This should solve that issue. I agree. try using the original freewheel and current chain and see if shifting is better. I'm guessing your axle is fine.
Please post more pictures including closeups of the axle, derailleurs, shifters, and the entire bike. This will help guide you better.
