Reduce the distance between the two Disks that center arbour are mounted on.
Use a staking punch or a metal tube with ID larger than center arbour OD. tap on disks to push em closer together, thereby taking the slack out.
Use of a thin washer like you say works too.
Hello, I am new to this website, but a watch lover. I have a mechanical watch which is pretty old, and it's crown broke from inside when i was trying to wind it up. The crown has come apart with the stem, and the gears linked to this stem are still inside the watch. Does anyone have any advice as to what I should do? Get a new crown or is there any way to fix this already broken one?
The reason it rubs is because there is wear in the bearing. Proper repair is to replace the bearing. Sorry no leads on where to source a bearing. I think I did cannibalize one from an Orient but that was a few years ago.
p.s. Even if you do file down the heads of the screw My guess is that the rotor will then hit the edge of the automatic device bridge.
