Please help a beginner! I’m having  Great difficulty in aligning the escape wheel  on this FHF ST96.

i checked the pivots,no apparent damage …bt the upper pivot won’t enter its Jewell , indeed when axially aligned the pinion seems to be nowhere near the 4th wheel teeth. So I spent much time repeatedly replacing the train wheel bridge, but no luck yet.the lower pinion is correctly aligned.

grateful for suggestions, please!

If you look down at the escape wheel's pinion in relation to the center of its wheel.  They do not look concentric because the pivot is tipped away from its intended location.  Can't see if the other pivot is in the jewel but I would hope it is.  Nudge it back into position while fitting the bridge.

Good luck.

Hi tony. Can we have a nice close up macro shot of the top pivot. This one is prone to getting bent when replacing the train bridge. It can be the last one to place and its the smallest of the trainwheel pivots. One trick is to place a screw in the bridge very lighty and work  the train wheels in one by one without trapping them.

Well, thank you one and all for the welcome advice.patience and perseverance won the day!

what I learned:

check all components under magnification.Take a break!

also I didn’t Take into consideration the side shake and end shake engineered into the components when assembling.

thanks once again all.

      You're probably not going to see a dramatic change but you should probably figure out what the lift angle is as it probably is not 52°

      In tandem with my last post regarding the removal of Google Adsense on this website - I have also decided to fully self fund this site as a gift to the watch repair community of which I’ve been a member of, and have benefited from since being extremely lucky to gain an apprenticeship back in the late 80s.    Well, that means that I have also closed down my Patreon account - or, to be clear, stopped all future transactions on my Patreon account and this is with immediate and permanent effect.    not to mention, but I will, I really really do appreciate the contribution all my patreon and PayPal supporters have provided over the years, you guys have been absolutely awesome and helped to keep this forum alive and available for those who might not be able to afford the payments.    again, from the bottom of my heart thank you.

      My pleasure. I would rather pay more than have those annoying ads ruin this site. They were a terrible idea and something I never even saw much, but I was on my iPad yesterday testing a security update for the forum software and it was impossible. I decided then - they had to go!!! Also, co-incided with this, for those who are paying for pattern in order to help fund this site - I’ve just disabled patreon. Future monthly payments will not be taken.  PayPal is a little more complicated. I will try to work out how to cancel the few subscriptions but if you are a PayPal donator then please feel free to cancel the monthly sub.  I will, however thank you all from the bottom of my heart for helping to contribute to this site financially - it means a lot. But going forward, I’m funding it personally from my pocket and that’s the end of it 😄

      Thank you Mark it definitely makes the site looked much nicer. Although I didn't mind the ads as long as it helped to pay for the messageboard but sometimes when you had the feeling that there were more ads than message board yes it was a little annoying. Thank you
