Replacing Oris Crown Tube (Friction Fit)

[jnash]

Any specific tools to push it out? or can i get a way with my staking set or maybe push it out.

 

Its for a modern oris?

 

Any help before i attempt it will be great.

 

Thanks in advance.

If you are replacing it with a new one, get a nail or similar that is a good fit inside the tube to stop the tube collapsing, and then carefully pull it our with a pair of pliers. Alternatively, grip the tube complete with nail in a vice, and pull the case away with a slight twisting action. It's worked for me in the past.

Thanks Geo, funnily enough I've never replaced one before! Any idea what the ridges on the end are for, I'm thinking maybe for a tool you can use

As usual thanks in advance

I've not seen one like that before Jonathan. Is that the end that fits the case or the crown?

Actually thinking about it . its probably just a cut away to match the ridge of the inside ridges of the case!

I thought it might be that.

The cut out should point upwards . Otherwise you wont be able to screw the case back down. So would be good to have the case back on when you put the tube in? Use some strong loctite on the tube. And remove the case back so it doesn't  fasten also.

i've just checked several of my empty seiko cases and the cut out is pointing upward. perhaps it's different on an omega?

As rogart says its to allow the case back to screw down so should face upwards towards the case back
