Welcome to FixYa!

Don't mess with the bobbin! They rarely need adjustment. Sloppy bottom stitches usually come from two things. Tension too loose on the tension dial or improper threading.

Dial tension should be set on about the mid range and you must, must, must, make sure that you have the machine in the proper thread patch. Have someone check it with you. Sometimes a fresh set of eyes will help you spot an area that you missed.

I have a kenmore model # 1581212180. My top thread is looping and when I change the tension then I get where the thread doesn't even stay in the material. I don't have a manual any longer.

Sounds to me like your bobbin tension is way too tight. Adjusting the top thread tension will not correct this. Either something is binding up the bobbin (thread or lint) do you wind your own bobbins? Perhaps you have a little too much thread on the bobbin and it acts like a break, stopping the bobbin from spinning freely. Check, clean and oil your bobbin shuttle (the thing that spins around the bobbin).

Hope this helps!

Motor runs but mechnism dont move

Broken or slipping Belt running off handwheel is most likely UNPLUG MACHINE FIRST !!
remove side cover, tighten motor adjustment to slightly slack like car fanbelt (not tight, some "give" is needed).
If you cannot easily open the case, take it to Service Centre or you WILL break casing clips.

My bobin thread gets tangled and loose

have you checked the tension? In the older machines you could adjust the thread tension by tightening the screw on the side of the bobin case. With alot of the newer machines you have to lift out the bobbin and then lift out the casing to adjust the screw on the underside of the casing.

Tighten the bobbin

Welcome to FixYa!

Are you having stitch problems? If this is the reason you are wanting to "tighten" the bobbin, then you should reconsider doing so. If you bottom stitch is the problem, then messing around with the bobbin is the last thing you want to do.....

Sewing machines are funny machines and counter intuitive. When people see problems with the underside stitch they automatically assume there is something wrong with the bobbin. In fact, the bottom stitch is created when the bottom thread interacts with the top thread.

The bobbin really doesn't have an adjustment and rarely goes out of whack. It's best to leave this alone unless you know what you are doing.....

So what....IS the problem? There are really only two things that seriously affect the bottom, in general, that is the tension setting (the little dial with numbers on it) and mis-threading the machine (make sure you are following the thread path exactly (sometimes it's not easy to figure out, so have someone else try it. Sometimes a fresh perspective will help you see what you might be missing).

Good luck and Thanks for using FixYa!

Euro-pro 464xc bottom tension loose

Welcome to FixYa!

Loose bottom stitches come from the top, not the bottom. Seems weird, but that's the way sewing machines work.

The dial tension should be set at the mid range and make absolutely sure that you have the machine threaded correctly. Both things will cause a sloppy bottom stitch.


If you find my solution helpful, I'd appreciate a FixYa rating....

Kenmore 15343 incorrect stitching

When you see the bobbin thread on top of the fabric this can be on e of 2 things usually. 1) thath the top thread tension is too tight or that the bobbin thread loose. Remember the saying righty tighty, lefty loosey. If you have adjust the top tension and it has helped just not enough perhaps you need to try the bottom a small screwdriver to turn the little screw on the outside of the bobbincase may do the trick. only small adjustments 1/4 turn at the most at a time to the right to start with.

Bobbin thread bunching

I had that problem, too, then realized my needle was in the wrong way. The flat side needs to be inserted AWAY from you.
I have a Kenmore 16528. It was such an easy solution! I was ready to take it in for repairs! Hope that helps!
