Disassemble steam and crown

[mrandazzo]

Hi guys!

I'm trying to disassemble a Seiko 7s26 steam. (my guinea pig: I need to learn before making this with a gen rolex crown)

On the paper its easy.

The steam is threaded, the crown too. Just unthread it.

But its not working! I'm unscrewing, but nothing happens. Should I push the crown? (the crown has a little spring inside)

If anyone can help me I'll be grateful

Just a little hint

Are you gripping the end of the stem where it's square with a pin vice to prevent it from turning?

Yes, its hold. Then I unscrew the crown, but nothing happens..

Just to clarify:

The steam its holded. The crown its turning and turning....but no disassembling at all.

Well then the crown sprung part that the stem is attached to, must be slipping. A sprung crown should lock when it's pulled out, and turn free when the crown is pressed in.

Look with your loupe where the stem inserts into the crown, as you turn it, to see if it's turning or not...

Ok. Slipping...slipping...angry.... broken steam!

I'm not worried about it because its my guinea pig and I need practice.

I shoot some pics of the steam-crown (just a few moments before it got broken).

So everybody could understand what I'm talking about.

The other steam's part its still inside the crown.

How can I put it off?

Any idea?

P.S. Thanks for helping a poor noob The Zigmeister

Well that's not like any stem I have ever seen, there are no threads on it...so it would seem that you have to pull it out of the crown, not twist it out...

Yes, its the same I thought.

I have another steam-crown from a Myiota quartz. This one is how it should be. Threaded into the crown.

Tomorrow I'll try with this one.

I'm trying to learn how to change the steam, because I bought a SSD (the new SD) but it have some problems. All the batch probably...I'm not the first with this kind of problem.

My tube its not so bad threaded (its not so difficult to screw back the crown), but the steam its too damn short.

So, when I unscrew the crown I ear the "click click" sound.

The winding pinion it's turning anti-clockwise "engaging" (slipping) the wig-wag pinion. That's what I guess! I'm only a noob

I think that this is not good for the toothing. So, if I change the steam with a longer one it will be better.

Am I right?

Try tackling the 'stem' before you tackle the "steam"......steam is hard to get a grip of...the stem is easier...

PS...I sense your frustation bro'....!
