ETA 2778 Cannon pinion slipping

How do you tighten this?  I flipped it over...did not help.

OK, I see this has been discussed here.

The best way is to get a new replacement. There is not enough to tighten the wheel its to thin, the cannon pinion is very hard and will split if you try to tighten that part. Not a good design at all.

Yup...a NOS one is on the way.  It is my watch that I got for next to nothing, so an additional $27 seems reasonable.  Yup, it is a stupid design.

All you can really try to do is put the wheel itself under the staking set and whack it on the hopes that you could bring enough metal in that it would grab again. But while I've seen individuals do it in seemingly it seemed to work once their worn out its I think it's much better to replace as closing at least in my experience didn't seem to work well
