Cannon Pinion Stuck?

[Watchingyou]

Hoping some one can help me out!

I got a Seiko Diver 4205 movement to practice (runs but stops).

 Stripped it completely, except the cannon pinion that seems to be stuck.

Should I really buy an expensive presto tool?

Also wondering if there should be so much movement/wiggling possible (see gif). Im barely touching it with my tweezers. Like no force whatsoever.

 

Thank you in advance!

 Try a stem holder tool, works just fine,  give the mainplate with canon pionion assembly a 48hr soak in Coca Cola first. 

This is one example where Coca cola works but penetrating oil wont be easy to apply inside the tube. 

You wouldn't know about the center hole/ jewel in the mainplate until all is disassembled and every part is checked, especially that the jif only gif ed a little,  .

And .Welcome to the forum.

Are you talking about a stem holder for keyboards? 

Hello and welcome @Watchingyou, if I haven't already said so.

Hello and welcome to the forum.  It shouldn’t wobble like that, center hole/jewel is either worn or broken.  You could try spin vice tightened over the cannonpinion and pulled vertically or a pair of hand removing levers if there is enough space.

No,  its full name is pin vice stem holder. See Bergeon 5679 tool.

Difference between that and any other pin vice?

No, its same tool.      

So  stem vice must be a  more popular name over younder.

Ok, just checked your profile, didn't realise you were from Iran.  Slightly differently terminology then.  I'm more into classical physics so if you want a chat on the free zone, feel free.

I once got kicked out of classroom in elementary school for asking a question and argueing with  my physics teacher that  he has not really  answered my question.   So if you think we can remain friends and such discussions be of any use or interest to our friends here, I got plenty questions.

We can definitely remain friends.

I believe so, because you have removed the bridge that holds the center wheel stable.  With the bridge in place, it will not wiggle.

Great, 

Would our discussion be of any use to forum members ?   

   I shoot a question anyway we'll  see what happens.
