I have been resurrecting a Singer IIIw155 made in 40s from storing it 20 years and I have dropped lube into holes but when I went to turn it I broke the timing belt made of cloth and metal bands and the lower shat with all the lifts and turns the bobbin area is locked up for some reason so I dryed areas and sharpied marked spots to save rotation and wondering should I disassemble the whole shaft and parts to see whats freezing it up?

Does it move at all if you rock the shaft back & forth?

Only when I loosened this screw below the bobbin rack connected to the shaft under. 
then it moves freely. When screw was tightened it moved about the slop of .100 or less but that’s the natural give. 
something in the bobbin case is jammed or rusted maybe.

Might just be thread jammed in the hook,put some oil all the way around the outside of the bobbincase & spin the shaft back & forth & it should free up.

Nope CowboyBob, after throwing a bunch of oil, only the Bobbin case with the lock and pad spins. no visual evidence of thread anywhere.

I guess ill have to take it apart from below spline and disassemble it all hopefully marking the spots to put it back together the same.

Yeah,alot of times it hides in there,if you leave the hook in there & just take out the 2-little screws on the ring  that hold the bobbincase in it might prevent you from taking the whole hook out.

If you take out the hook remember to remove the case closer or you’ll break it off - been there done that.  Lol

Got the whole shuttle assembly off by loosening the items on the upper shaft and sliding the shuttle left and it barely cleared the feed dog assy. Sure enough when I gently moved the shuttle with Knipex plyers, I got it to rotate but rough so took it apart and had rust spots. Using aviation small steel brushes on drill motor to clean and get it moving effortlessly! Still marked more spots with electric clean to dry area and sharpie’d but crossing my fingers I get timed machine which I’ll have to get new motor too, maybe a Tacsew model.
