so.. i can't seem to find the correct headline, forum, whatever it's called here...
need some help, input, direction --
i just got back a slightly damaged seiko skx173.. with a 7s26c...all original.. and very 'clean.. from 2017 yr.. it was 'jammed'.. the person 'claimed' they dropped it ..???.. opened it up - found the 3 slotted screw/nut to the secondary reduction wheel and that wheel - off - rolling around free..the screw/nut looks as if there is no threaded shaft to screw into the bridge.. the wheel looks like the very edges of some teeth are slightly 'blunted' vs sharp point..i cannot see the broken shaft in the 'riser tube'??
i released the spring pressure on the ratchet wheel & removed it.. loosened the bridge screws slightly - cut a thin strip of wht paper and slid it just enough to view it passing underneath.. so - the tube/furrel/rotor post -(learning all new correct terms) is not blocked - no obstruction - i can see the paper sliding under..
not having a left handed screw - though the ratchet wheel screw is just about the same dia - wrong thread - poss same length - i get a better idea..
taking a small pin - and sliding it into the ratchet post - as a reference - to 'feel' the threads and resistance as a base line - i'd say my 2nd wheel post is approx 40-60% - threads, depth, count, defined and not completely 360 degrees - so it has suffered some damage by the sneaky person who pretended not to know what happened..
i get that the tube/post is pressed in - but it might be easier to just get a bridge plate - then new 2nd wheel to be safe - and screw/nut.. or 2 .. if - if - i find that the existing post is 50% stripped out with the first nut install- and i'm not getting a good secure 'grab'
of all the pics online - none depict how long that shaft is on the screw/nut.. and since i don't have a complete one ..?
i'd prefer to simply obtain a newer bridge plate assembly with the first reduction wheel, pawl, secondary reduction wheel and poss main ratchet wheel? attached and in like new condition - so i could easily swap them out as an assembly/unit.. vs - swapping each piece.. or a new 7s26c movement - plus date day wheels, dial, hands ..
i should mention - after making sure nothing else was 'loose' or 'floating around' - i wound it by screwdriver - and its been working fine for days.. runs a bit fast - but i 'tuned it' a bit - now is 3-4 fast min per day - which i can refine after swapping out the 'auto winding' parts section..just wanted to ensure everything else was 'normal'
so - help... anyone have this assembly.. or direct me to where i could get a newer 'clean' one..
otherwise my options (in order) - locate each part - new and a hubble to see what i'm doing - but pricing is close to a new movement.. not good.. a new 7s26c and do the swap -mvmt - to keep it all original (value wise).. or nh36 plus more parts and either steal from 7s26 or add to the parts list and it runs like it did before - but lost it's OEM value - esp for being 5 yrs old and in excellent if not better condition..
open for your input.. excuse me if i keep getting in the wrong 'area'
