7s26 Barrel problem


Recommended Posts

i want to give a quick update, thamks for the tips, i rewinded the barrel and it gave juice to the train. And after a few dismantlings of the barrel bridge, i found what was wrong, the pallet fork pin was crushed (i think my fault) and i broke 2 balance springs (happy i had reserve). After the cleaning and oiling i checked it on the timegrapher:

    • Hello everyone. My name is Gary.  I’ve been hobby fixing for just a few months now and have turned out several Seiko 7009A, 6309 and 7s26 movements with varying success.  my first movement was a tiny Cyma 424. (In at the deep end for size).  I’m currently working on a sentimental Garret ETA 2391 for my Father in law. 
    • Thanks for all the replies.  I'll investigate further.  I never noticed the lip and @Michael1962, I think I will have to form a tool to undo the ring and see what happens. I'll see if I can get some more pics.  
    • Hi John, The most important parameter of the spring is the thickness. The lenght is something that one would not consider as obligatory, as relatively big variations will not affect anything in significant way. The barrel size is related to the barrel and has nothing to do with the spring. Yes, the spring is designed to work in a barrel and the size of the barrel matters, but let this parameter be chosen by the movement manyfacturer, not by the sping manyfacturer who doesn't have idea in what kind of movement the spring will work. Sometimes the washer in which the spring arrives will be bigger than the barrel and there will be no way to just push the spring in the barrel and be happy. Well, if this is a problem for somebody, then probably He is a person with to many problems that will be verry hard to help to in any way. By the way, why You are changing the spring? Is the old one broken?
