Does anyone have experience with the Doxa 103/ETA 2391?

Hi guys,

I have been working on an old Doxa antimagnetique that doesn't run, and stripped and cleaned it. However, as I am putting it back together, the cannon pinion, which seemed friction fit when taking it off, isn't friction fit after all. There is an hour reduction wheel on top of it with what I think is a friction collet, but that one is completely loose. See picture below. Question: do I simply bend the collet to make it friction fit again? It feels a bit rough to do so but I assume that's the way to go? This is a Doxa 103 movement, based on ETA 2391.

Any help much appreciated!

I didn't work on 2391, however a 2390 is about to get hit by my swift hands...

242 should be the friction part. I don't know what to do if it's too warn out. Maybe you should replace it.

I don't think it is the classic cannon pinion which can be tighten...

Great, that already helps, from the description it seems the cannon pinion is then fixed onto the friction piece. Thanks!
