Alarm setting lever repair

[steve1811uk]

Hi, I have a small problem with the alarm setting lever (date correction pusher) on a Seiko 4006A Bell-Matic movement. There is wear on the pusher pin of the alarm setting lever. The use over the years has worn a bevel on one side of the pin. Due to the wear the pusher stem can sometimes slip under the pin on the lever as quite a bit of force is used for the date correction. I am thinking that I could file a flat on the pin as a bit of a bodge solution to stop the stem sliding under. Or I could try and knock the worn pin out and make a new pin and friction fit/ rivet it in place. Has anyone experience of doing this before, possibly on a setting lever as that would be similar. I do not have a lathe but I have a Dremel tool and file that could possibly work. I also have a good staking set that can be used. I would need to know what material to use (some kind of steel) and also consider the hardness and the security of the pin on the lever. Hope this makes some sense. Thanks in advance.

Have you thought about trying to rotating the pin 90 degrees?

Or even just getting a new lever?

I did have that thought but not sure how to go about it and a new lever is hard to find. Do you think it could be rotated and fixed firmly back in place?

As it's friction fit then I expect you'd be able to rotate it.

Not hard to find but not cheap.

How is that pin actually fitted ?

It's the shipping costs that make the situation even worse

Some kind of riveting I think. Watch is back together so I can't have a good look.

I went back in today and managed to rotate the pin by 90 degrees. I had to knock the pin out with the finest stake I had which was about 0.4mm diameter. I closed the hole in the lever just a touch with a couple of domed stakes before driving the pin back in nice and tight rotated 90 degrees. I then spent over an hour looking for the date jumper that had pinged. I used the Bergeon fridge magnet without any luck and when I finally found the part on the floor I found that it was not magnetic Anyway all's well that ends well. Date correction is now working perfectly with no slipping.
