Have an Urgos uw03083 grandfather clock movement that need some advice on. Brand new movement but made the mistake of removing the arbor shaft so could get more cable out so could hook on the weights. I marked the gears but has gone downhill since then. Have three pictures, showing the top and bottom of each gear. On the top of each, there is a line made in the gear. Underneath, are cams (probably not correct term for them). On third picture, I did a sketch showing relationships between top and bottom. Arrows pointing to top mark, blocks the cams. The problem I am having is the each train stops at a different place, the cams have connected and stops the train. I thought I had it when having to two marks pointing to each other but definitely not right. The right gear has 25 teeth, the left one, 24. I have never worked on this kind of movement before so only guessing this is to stop the train before the drum is completely unwound. So my questions are, 1, what exactly are these cams for and 2, what is the correct locations for the marks so it works correctly? Playing with old movement, seems like the winding gear if pointing up and idler gear pointing down, I get about 14 rotations before it stop but I have no idea what is right. Thanks for any advice.
