LoveToLearn Report post Posted February 18, 2016 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 LoveToLearn Quote Share this post Link to post Share on other sites
TomG Report post Posted February 18, 2016 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? Tom Quote Share this post Link to post Share on other sites
LoveToLearn Report post Posted February 18, 2016 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 LoveToLearn Quote Share this post Link to post Share on other sites
Constabulary Report post Posted February 18, 2016 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. See attached picture Do you have a parts list and manual for your machine? If not download them. Quote Share this post Link to post Share on other sites
TinkerTailor Report post Posted February 18, 2016 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. Quote Share this post Link to post Share on other sites

If not download them. 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.

Constabulary Report post Posted February 19, 2016 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. Quote Share this post Link to post Share on other sites
Wizcrafts Report post Posted February 19, 2016 (edited) 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. Edited February 19, 2016 by Wizcrafts Quote Share this post Link to post Share on other sites

shoepatcher Report post Posted February 22, 2016 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. glenn Quote Share this post Link to post Share on other sites
gottaknow Report post Posted February 22, 2016 Glenn is correct, many times the spring can be bent back. With the right small screwdriver, you don't need to remove the basket from the hook. In fact, I usually remove just the adjustment screw, clean out the area, then place a small screwdriver vertical between the end of the spring and the adjustment hole. Push in with the spring over the screwdriver and reinstall the adjustment screw. It's easier to start if you loosen the anchor screw just a bit. Just make certain to re-tighten it.

BigMatt Report post Posted February 23, 2016 (edited) LoveToLearn,This video is the most important video I watched when I was trying to learn to thread my 111 Singer. I could not get any bobbin tension no matter how much I tightened the spring on the bobbin case. I tried and tried and it would never work. All the videos I watched all said the same thing, "drop the bobbin in, slide the thread under the triangle part, take up the bobbin thread and you are ready to sew." The problem was, I never could get any bobbin tension.This video changed everything. After you pick up the bobbin thread with the needle, put your finger on the bobbin to keep it from spinning and pull the thread through the hole until the thread pops under the bobbin tension spring. You will hear it and feel it. It should have tension after that. If it won't pop under the tension spring, you may have adjusted the tension spring too tight. Loosen it up until you can get the thread under the little black spring.I hope this helps... Edited February 23, 2016 by BigMatt Quote Share this post Link to post Share on other sites

gottaknow Report post Posted February 24, 2016 No worries BigMatt, I didn't take it that way at all. It simply reminded me of all my factory years and how many times I've said it, even reminding experienced operators, supervisors and apprentice mechanics.
