I'm having a pig of a time with my first rebuild.

the barrel arbor has a larger diameter than the centre coil of the mainspring and I just can't get it to sit down in position and engage the spring and pop through the case hole enabling me to get the barrel closed.

Are there any tricks of the trade someone could tell me about here?

I must have watched Mark's film of him doing it 20 times now and I can't see that he has this problem in the slightest.

It's the Seiko 5 7009A still.

 

thanks!

I use a small pin vice to hold the arbour tightly.

This lets me manipulate it easily into place by pushing the arbour in at a slight angle while slightly turning against the direction of winding. Once you have it in place, turn the arbour in the direction of winding to ensure that the hook has located properly with the spring before removing the pin vice and closing the barrel. :)

The barrel arbir holder makes this even easier and its not so expensive

I've not see one Emso, could you post a picture please?

I shall definitely do this on the next one!

 

thanks for all the advice gents.

hugely appreciated.

Here is the picture ,there are different diameters, but i have bought one and use it for all modern movements

Thanks for posting Emso. :)

Having seen it I can't help but think a pin vice does exactly the same and can also cope with other things as well.

I was asking in another post what were the most useful diameters, but never got an answer...maybe this is a good time to ask again?

Nice Geo, thank you for the picture. I figure I may as well start collecting them. My pin vise is frustrating at best sometimes and it is no good for holding arbors!

 

Cheers,

The pin vice will scar the barrel arbor, the barrel arbor has a hole in the middle which will not svar the arbor, if scared you will have wear on the barrel where it touches the arbor and possibly a weak amplitude

I do it this way all the time and haven't marked one, the hardened steel of the arbors are very resistant to damage.

    • If the watch is new, just return it to the seller for a refund or replacement.
    • Keevo, Welcome to the group ! I'm thinking that you have some damage to the hour, and/ or minute wheel. Possibly just a bent, otherwise damaged, or missing tooth.   Your photo didn't post that I can see. I think you'll have to open it to start really finding the issue. Best, Randy
    • An industrial break cleaner , like Holts does a good job of rinsing off paraffin 
    • In cap jewels on several watches I have serviced over the years. I've recently serviced a couple of Longines movements where the cap jewels were colourless. They are a real pain. Without colour they disappear when immersed in any liquid for cleaning 😲 Not necessarily. Cousins do a 10ml bottle for £26 which will last me for years. That's just half the price of a simple Bergeon silicone cushion, so not too expensive 🤣
    • I wanted to post an update as I have two movements running really well now, 230-250 amplitude , 0.5 and under beat error, and +/-8 seconds or so. I removed the hairspring assembly in order to start over and noticed that the terminal curve between the stud and regulator arm was distorted. The stud was lower than it should be. I massaged the curve to look pretty good and reinstalled it. I followed Alex's video advice, best I could with 10x magnification, and with the regulator arm set in the middle of the curve I adjusted the stud so the spring was centered. I then made sure I could move the regulator arm the entire terminal curve without upsetting the coils. I then put it back on the Timegrapher and began closing down the regulator pins until I saw a change in amplitude which means to me that the pins were now pinching the spring. I opened them slightly and it looks good except I have a 0 on dial down, +3 on dial up but -16 on crown down.  I'm a bit stuck on how to adjust out the positional error. I also noticed a drop in amplitude, 180-200 on crown down. In the other video link I posted at about minute 26 if I remember he adjusts out positional error by manipulating  the regulator pin gap. With crown down the hairspring falls away from the pin and the rate slows so he closes the pins a bit to keep them tighter in crown down position. That means the spring is tighter on dial up as well but then he moved the regulator arm to slow the movement.  There must be some Seiko experts here that have some methods for dialing out positional errors.
