Yes, the arbor usually makes about 3 to 3.5 turns. But usually spring takes 2/3 to 3/4 of the free space in barrel, not 1/2, so take it for the calcullations. This way the change in torque is smaller. I have a picture for You, this one is little older, but no mater -
I overhauled a ladies Rolex and noticed erratic performance so I stripped in down again and did fault finding. This is what I saw. The lower jewel (the one in the plate) is cracked and the hole is too big. Before discovering this, I stripped down and re-cleaned the main-plate (and parts) by hand with a fine natural fiber brush. I somehow missed the fault the first time and cannot understand how it was still running. Perhaps re-cleaning it dislodged some pieces of the jewel widening the hole? I don't know. Now I need to replace the jewel but don't have a Seitz tool. The Rolex part is 2130-0913 and the top and bottom are the same. The part comes complete in brass setting with KIF elastor spring and cap jewel. Note: I have never replaced a jewel. I do have a good vintage stacking set that I've used quite a bit. Can I replace using a stacking set? Any suggestions would be greatly appreciated. -
Is there a tech sheet available for the 6601? I've only been able to find a parts list. If there isn't one, would there be one available that is close enough to follow along with? -

I've used expanding foam for lots of things but i thinķ you got me on that one. -

This happened to me several years ago when I first got my barrel closing tool. In my eagerness to try out my new tool, I closed the cap without the arbor. I don't quite remember how I opened it. I might have used compressed air to pop the cap off. I sometimes use compressed air to open those "sealed" Seiko barrels.
