Rotary Automatic Rotor Loose

[RedJim]

Got this Rotary Automatic, its running but intermitently stops. The Rotor seems to be loose, I thought this might be the cause as the balance is free running. if you rotate the watch from side to side there is some movement up and down if I've explained it properly. It also rattles when you move your arm when wearing the watch. I'm not sure if this is the reason for intermittent running/stopping, could it be touching some other component when its in a certain position? I was going to take it off and try to reseat it but I haven't done this before. It isn't screwed down, is it a lever off and how would you go about it? Or does it just need pushing down to reseat it? I'm still a novice and really don't want to damage it. Any help appreciated.

Hi If the rotor is loose you have problems in it winding properly so that problem wants sorting out first, Likely a worn/broken axel or if you are lucky a loose axel mounting,  What is the make and caliber number. I can see its a eubauches but cant make out the number or the maker, do you have the tech sheet, Usually they  are screwed on or have a little locking piece which has to be removed, Do Not lever anything off as damage is likley to occur. Thats why we need the make and number so members can identify the movement and help you.

Hi, Its a AS1883 Movement. I can wind it manually and its ticking away fine. I have a tech sheet (attached). I can't see a screw but am struggling to see how it attaches. Thanks.

The screw might have fallen off, its suppoe to secure a spring that holds the rotor gear in place on the axel, so see if you can slide the spring outwards, rotor can then be lifted.

Could this screw/slider be what I'm looking for to realease the Rotor? It has arrows on it.

Yes, slides out easy as arrow points,

Joe has the answer un do the screw and slide/remove the bolt piece.
