550 series center wheel bushing 6107

Currently working on a 564 that is completely full of oil, and found that this particular one has a tiny little bushing that had fallen out of the center wheel.

A bit of detective work led to me thinking that it should be the center wheel bushing 6107, however looking into what data sheets I can find I no longer see this part listed, and I can't say I have noticed this bushing on any other 550 series movements I have worked on in the past.

I was wondering if anyone knows if the advice on using this bushing has changed?

EDIT: and nevermind me, I found the answer in a post by Archer from a few years back, https://omegaforums.net/threads/movement-evolution.117856/

now to hunt out a newer center wheel with the integral bushing

I actually found it as it was loose in my cleaning basket, and as that basket only had the train wheels in it I had the theory it was a bushing, and a bit of a google even gave me a part number to compare with.

for now I may just press it back into the center wheel, as my 550 series parts box is lacking one of these.

I'll set up the microscope later and take a pic

The sheet for the 564 says this part of the base caliber 563 is the same.



Hope that helps.

Pressed the bushing back in

The other center wheel I have in my parts box doesn't appear to have the integrated bushing, so I wasn't sure if it would be better to go with this one or the one with the bushing.
