Loose escape wheel under train bridge

[brunomartins]

Hi, Bruno here! 
 

I have worked in a couple movements last weeks and had found the same issue: loose scape wheel under train bridge. I have tried everything to properly set the bridge, the wheels run perfectly without the loose scape wheel, so I assume with high confidence the problem is this wheel.

Well It seems very probably the its pivot is shorter or broken (despite couldn’t find like this).

my question is if this a common situation that I should insist in trying to engage the wheel or it’s indeed a pivot problem.

(the scape wheel doesn’t stay fixed)

Some close up photos would be helpful.

Were they loose before you started working on them? What is the history of the watch?

Just look at the pivots, you should see if one is broken. If you can't see, you need proper magnification. If the pivots are ok then there might be too much end shake or a jewel is broken.

Sure. I should’ve done before.

here is the guy.

I am beginner in the job so I am not used to how looks a broken or wear tip of pivot…still learning. But looking at this pics I think the top pivot is really short.

the history is simple, a Raketa with 2609 caliber purchased on ebay . It was working needing to be shaked to start after winding.

Yes. I have just posted pictures of my magnifying tool. I think one of pivots is really short seems worn

First pic has an intact pivot, second pic has a broken pivot.

You concluded correct bruno. There is barely anything left to sit in the jewel. I'm affraid nothing you can do with this.  A new escape wheel or from a donor watch required

Or just repivot it! I kid, I kid. Unless it's a movement where parts are unobtainable. I still have an Omega 321 chrono movement here that the client is hunting down an escape wheel for; broken pivot. Replacements cost more than repivoting. I think we'll repivot in the end.

Repivot is an advanced ability I can’t imagine. Currently I am practicing unfortunately losing some cheap working watches  

I would like to purchase an omega seamaster from 70s or later so I can clean and oil by myself but the price on ebay is going up recently

Progress at your own pace. There is no hurry. But keep moving forward.

All of us have made mistakes along the way. Don't dwell on them. But learn from them and move on.

Continue practicing on expendable movements before something you value. Whenever possible, look for a replacement movement, just to know how it would hurt if we screw up. 

Press on and enjoy.

Hello
@brunomartins and @HectorLooi

Personally speaking, I try to buy at least one practice movement for every working timepiece I plan to service (some day, when I have all of the required tools...sigh).  That way, if a part pings into oblivion I have either done it on a non-working movement, or I (hopefully!) have a spare that I can take from the "practice" movement.

Yes, this balloons your inventory immensely, but I think it pays off in the long run as purchasing service parts is proving increasingly difficult and expensive.
