Singer 111W-155 I Cant Get Any Bobbin Tension.

[LoveToLearn]

I have adjusted the screw but even at maximum tightness there is ZERO bobin tension. Is it possible that little spring got stretched when I had a tangle and was trying to pull it free? I have taken the sliding plates off and the feed dog cover and looked in there at the little spring. How can I take the bobbin case out so I can examine the status of that spring and bend it back into shape?

thanks

Why not just buy a new spring. Check with sewingmachines.com or one of the sponsors in the banners at the top of the page?

Is no bobin tension a common problem in these old machines? I mean is it unheard of or, is it common that the spring gets messed up and needs to be repaced? Anybody know how that bobin case comes out? Is it just two screws on the hold down plate or is there more to it? Is timing going to be affected?

Thanks

Have you turned the right screw? There are 2 on the spring one for holding it (the right one) one for the tension (the left one). The 111 are old machines and the spring is a wear part like the entire hook an many other parts. Sooner or later you simply have to replace it.

When you are buying a new spring I´d buy new screws too. They are tiny and when you loose em you are screwed.

Do you have a parts list and manual for your machine? If not download them.

Before you replace it, make sure there is no thread pieces stuck down in their from your tangle. Get the bobbin case out, and check everywhere the thread goes for stray hunks of nasty.

Nice diagram. Thanks.. Do you know where the cheapest place is to get this part number? I have a parts manual. Im assuming the number is in there but where is the best/cheapest place to get a genuine singer part? Also I was wondering, is it normal for the bobin case to oscilate slightly?

Thanks fellas.

The days of original Singer parts are gone! If you can find original parts they are for sure a bit more expensive than after market parts. Some dealers still may have some OEM parts in stock. Try Toledo Sewing Machines or Keystone Sewing Machines.

Any remaining unsold/unused (NOS) genuine Singer industrial sewing machines parts will be held by dealers who were in sewing machine business in the late 1980s or early 1990s, while Singer's industrial sewing division was still in operation. Both of the dealers listed by Constabulary meet that criteria.

One final thing, take the old spring out and wee if it has a grove worn in by the bobbin thread. If so, discard it. If not, and you are careful, you can re-bend the spring to make it work better, i.e. make the radius on the spring smaller by bending it with your thumb and index finger. I have done this a lot over the years and it works to put tension back into the tension spring.
