I do not remember of a 201 has a set screw or if the post is threaded. If it is threaded you do not want to bend it. Put the end piece on and turn it lightly with a screw driver. If it is a set screw you will see one if you look around above or on either side of the tension barrel. Tammi has some wonderful videos on 201 tensions. I think in the resource section.
While you have that open, take the pin out and clean it in 90% rubbing alcohol or naphtha. ive seen a lot of tensions gummed up right there. Until that is clean the tension won't pin won't retract. Do not get the alcohol on the shellac part of the machine alcohol will dissolve not just the gunk and oil but shellac as well. Naphtha will turn the shellac cloudy white so be careful with it, too but if alcohol won't remove the gunk naphtha will. Evap-o- rust is a good product but vinegar will take off rust too. Be sure it is rust first. Some dried on oil is the same color. Dried oil will be a bit gummy.
