Balance resolved but not done yet...

After unscrewing the v-conic screw completely and tilting the balance enough I got it in there. And pinning the h/s wasn't half as tricky as I feared. The balance now swings nicely with a little pressure applied on the wheel train. 

But now I'm stuck on the winding mechanism. ? For some reason (?) there's a little axial play in the m/s arbor and the "planet wind pinion" that ends in a squarish shape that's supposed to sit in the squarish hole in  the "planet pinion ass'y"  and take the force when winding, slips back and no longer holds the planet wind part. In a regular swiss design, this connection would have been secured by the ratchet wheel screw but this is different....

If I apply a bit of pressure on the opposite side of the pinion, I can wind the m/s but as soon as the pressure goes away, the pinion slips back a bit and looses the grip in the planet part. 

I have attached a couple of pic's showing the "good" pinion position with its end flush with the two planet wheels and the "bad" position where the pinion end is lower than the surrounding planet wheels. 

I actually think this was the problem from start rather than the m/s not hooking onto the arbor. 

It somehow feels like it should be possible to shim somewhere to maintain the pinion in the good position but I can't get my head around where or how.

I wonder, how does it make you feel? Frustrated? Perplexed? Both? Good thing this is just a beginning, because it will get worse.

Can I choose both? If we’re having a therapy session I want all options available on my way down... ?

Sure :-). I ended up buying a NOS movement. It did not look 100% as mine, but indeed it was the same movement caliber. Since it came without the oscillating weight, I simply transferred mine. Still have the old one put aside - this is my "when i have free time" project aka "never gonna happen".

I keep hearing about NOS Timex items but can’t see any where I usually look for parts and donor movements. I’ll take a hint towards that slippery slope any day...

I bought it from JerseyMo. Ask, he may have what you need.

      B-Dip residue?

      By KarlvonKoln · Posted

      One-dip or naphtha should be safe, but are you sure it isn't magnetized?  I would also check that.  Although, if that balance is from an Elgin 760 0r 761, I would think it would have a hairspring of non-magnetic alloy.

      Replacing armoured crystal in a front loading watch case…

      By Curare · Posted

      Hi John I just did a Seiko Lord-Matic a front loader without a split stem, I used a crystal lift to remove it, although I had to have it that tight I though I was going to break the lift before the crystal would budge. So I decided that the press would be a better option as I think crystals with tension rings resist a lot of compressing. I used a crystal press to repalce it and the bezel with no issues, obviuosly a different watch to the Omega. I just took my time and kept inspecting the installation progress bit by bit Regards CJ

      Replacing armoured crystal in a front loading watch case…

      By Zendoc · Posted

      Hello All, I’m replacing the crystal in an Omega Dynamic, # 165.039, which houses a cal 552, installed through the front of the case. The replacement Sterncreuz crystal is, like the original, with tension ring. I removed the crystal using a compressed air technique to pop it out.  (I have a crystal lift, but I’m always fearful of marking the crystal edges and so avoid using it as much as possible). Now to the replacement -  any tips on putting the crystal back in?  Am I obliged to using my dreaded crystal lift to complete the task, or how about a crystal press?  I’ve put lots of crystals in using a press, but never with the movement in the watch. The thought of using one with a front-loader makes me very nervous, with the fully assembled watch sitting under the press. How would more experienced folks proceed here? Any advice, gratefully received… John Down Under…

      No thats straight out of the watch as i found it the balance wheel is almost as bad. I've never seen so much material removed.
