How to replace a sac in CS 100? Any tips beside the classic routine like heating?
Is the section screw-on?

I would say that when in doubt, always assume it's a screw-on and twist after heating. Some can be really stubborn and you need a lot of patience and repeated heating to loosen it up. I had a horribly stubborn one that I started having doubt that maybe it was super-glued in by previous owner? But in the end it gave in. Patience patience and gentle. You can use a thick rubber pad (or two) to help get a better grip, or even using a pen plier (always padded by rubber), but be careful not too quick and abrupt. You can crack the barrel. Good luck!

It should not be a screw in, and the servicing is exactly the same as for most of the 1950 CS models.

 

Of course this is one of the most expensive models of that period, so probably not the best to be learning on.

Thank you guys. Meanwhile I contacted the previous owner who replaced the sac, he says he did not glue the section to the barrel. So hopefully it shall be fine.
