Hello,

 

so I‘m working on this Rolex 3235. It has a new wheel train compared to the 3135, minute wheel (blue) and fourth wheel (green) both in the centre.

So the upper bearing for the fourth wheel is a jewel in the minute wheel.

And this one woobles. I think it is not press fitted but just put in and secured by caulking (there are very tiny dents on the radius).

So how can I fix this? Just use a conic punch in the staking set and hit it with a small hammer very carefully? Do I have to hold the jewel somehow during this process to ensure it is positioned absolutely flat? Or is there a better method?

A spare part is availiable but expensive. So I would like to try a repair first. If I fail, I still can buy the spare.

Sorry for being off topic: Why do you think the central position of the second and fourth wheel is a new design? The jewel bearing of the fourth wheel inside the second wheel is identical with the cal. 3135 imho.

      Seiko 6601 Tech Sheet?

      By JohnR725 · Posted

      yes I noticed the new site and I miss the old site. It's the unfortunate problem of the Internet here today gone tomorrow sometimes some of the stuff gets backed up and sometimes well it does not then the problem with the early Seiko's were there were not necessarily designed for distribution across the planet and as such there is no customer support for them. So trying to find early stuff like technical information or sometimes even parts list for older Seiko is is problematic. But I did find you a you tube video. A quick look he seems to take a heck of a lot of time to actually get to the service single I did not watch all that but it does look like he did disassemble or started to say there's a tiny bit here

      An intro…

      RichardHarris123: Hello and welcome from Leeds, England.  I have family all over Australia, went as £10 poms Thanks Richard. Hope you’re able to visit your family here and that they’ve all done well 🙂 My relatives arrived from England in the 1790s transported on the ‘Second & Third Fleets’—a story of timber sailing ships, of convicts and doing well in this huge Country of Australia. When I visited the UK in the 1980s, I was too young to comprehend the depth and breadth of its history…  Best wishes, Mike William Chapman, my 4th great Grandad’s charges, at age 23 read at the Old Bailey; sentenced to 7 years of transportation to Sydney.

      New balance staff not riveting to balance

      By Endeavor · Posted

      The whole process and the progress are closely observed, it's hand-driven and very controlled. I can't see the "danger", unless you are watching the TV while doing it. As you could have read, and in this quote "wheel" is the balance-wheel.

      AS2063 - hand setting

      By Mercurial · Posted

      Have you got the pallet fork installed in the movement when you see the train move when using the setting works? As nevenbekriev said, without the pallet fork to lock the train, the behaviour you are describing is normal. If this is happening with the pallet fork installed, you have a problem in the gear train, it should be immobile when the pallet fork is locking the escape wheel.  The fit of the circlip above the pinions on that wheel is crooked in your pictures, it should sit flat up against the upper pinion as in Marc’s picture.  Hope that helps, Mark

      Stem broken - can it be rescued?

      By Khan · Posted

      Hi I got a Jaeger LeCoultre K911 movement, where one of the stems was broken. Part no. Should be 401.  Im based in Europe and tried Cousins but its discontinued. They except to get stem in stock for cal. K916 but will that work? Or Is there a way out to join the ends?
