Excited about my Viking 12-1, I dug in and cleaned it, freed up the frozen places, and then had to re-time this baby. Did it come needing to be timed? I doubt it, but in order to get everything moving I released the lower shaft and figured that was going to be the price. Here's the part I released:

Hook drive shaft with hook mechanism in red box, screw to release with green arrow |
The green arrow shows the screw I unscrewed that got everything moving but it also threw the timing off. When I went back to set the timing I couldn't figure out exactly how this was going to work without a special tool to measure it, something I always imagine the techs would have. Maybe not because a lot of it is just eyeballing it and testing over and over again. I could move the hook but it never seemed to be right, either way too much or too little, never getting the fine tuning right. When I sat back and looked more closely I discovered I was moving the hook way too easily and how was it going to stay in place?

Taking everything out and moving slowly, I could see how it was supposed to work:
|
Red arrow for hood, Green arrow for the needle |
As the needle goes down the hook comes up and catches the thread as the needle retreats. There is just a small gap that is created for the hook to catch that thread. Pretty cleaver, huh? But I couldn't get the hook to stay in the perfect place because I failed to tighten the screws on the shaft in the first photo.

Of course, once tightened up it only took a little finessing to get it right and a final test and tightening. I could hardly believe I forgot how to do this but, heah, it's been a long winter and spring is finally here! I got the Viking 12-1 all threaded up and sewing in no time, sounding wonderful and with a bit of a zig-zig sound that is music to my ears.
So the Viking 12-1 that I picked up free but all frozen up, now works and is going to be a mighty fine sewing machine. I can't find a manual but it's pretty straight-forward. It came with a green metal hinged Husqvarna box with an oil can and set of bobbins but it really takes standard class 15 bobbins.

This is a nice addition to a classic sewing machine that has so little written about it. Another oldie but a goodie, all for your reading pleasure:
