side-shake /end-shake what is the proper way?

Recommended Posts

Ok guys i have a question for you for example on a balance wheel wheel that has too much side shake what is the "proper way" to fix it do you replace the balance staff or the jewel or do something else and how about the on the train wheel bridge is it the same do you change the jewel or replace the gear how can you tell for certain that it has excessive side shake  and that brings up my next question what about end shake what is the proper way of doing that i saw in one of marks videos that on the balance wheel he had a video of the the pocket watch movement that he does in his training course when he used the screwdriver to tighen the screw he ballence stoped becaouse it didnt have enough endshake so he saw a bump on the mainplate that when he cleaned it or whatever he i guess the bump whent down flush with the movement and didnt allow clearence so he just put a new bump on it he said the is not the proper way but it is what some watchmakers do to cut the cost of the repar and save the customer money so my question is what is the proper way and is that way differnt for the train wheel bridge

The proper way to adjust end shake is to move the jewel with the jeweling tool. 

Side shake is more problematic. Replacement is ok in the train. For the balance however, the balance itself should be replaced if the pivot is worn out.

    • Hi jdm, thank you for your interest. I have worn this wonderful watch every day for nearly twenty years and there is a fair amount of play in the bearing, not rubbing against workings or caseback yet, but noisier than it used to be.
    • What's wrong with that one? Some play / noise is normal.
    • Thats incredibly bad news. I was sure that this would not happen with the genuine article. I didn't order from Cousins and it will probably be a hassle for me to complain.

      And the official answer from Bergeon is the worst. When you are a customer who has paid good money for a product that is defective, you do not want to hear "Well, we acknowledge that there is an issue with your product that renders your purchase useless, but other people have not complained, so you should be fine"
    • Please advise where I might purchase an oscillating weight including bearing for a Seiko 7S26A, I live in the Eastern Cape, South Africa. Thank you.
    • Hey guys! Great information here. Teaching myself some basic watch maintenance. Really just starting out. Bought this with a view to "learn by doing". It wasn't winding when I started. Had an amazing time taking it apart and examining the parts. The hairspring seemed bent so I had a go at shaping it and damaged it even worse. The study came off and was lost, then part of the spring knotted ... Argh. I'm murdering this watch I know! I'm having a really tough time finding a compatible replacement. The parts chart says that the balance is "different from basic calibre 100" and to "refer to catalogue GF 239". I can't find any document by that name. If I could get some help it would be appreciated!
