I can't seem to adjust my tension--I have it at 0 and the thread still lies on top. Any solutions?

make sure the thread is between the plates and not behind one
0 will be no tension and the tension gets tighter as the numbers go higher

My bobbin thread is showing through on front please help

Loosen your top tension. If it is too tight, it will pull the bobbin thread to the top of the fabric. If it continues, then it may have to do with the thread weight you are using in the bobbin or the bobbin tension needs to tightened slightly. HOWEVER, adjusting the bobbin tension is usually a last attempt. It is a sensitive adjustment.

I frequently use a lighter weight thread for quilting and need to adjust the bobbin tension. So, I have a separate bobbin case that is adjusted for that purpose only. Having to adjust the bobbin tension every time one changes the thread weight is a real pain. For most general sewing, the factory set bobbin tension should be sufficient.

Adjusting the bobbin tension

hi genevieve.
this is all i could find.
To make a temporary tension adjustment, select the threads for the needle and bobbin, then fill the bobbinand thread the machine. Make a test seam on the fabric that you plan to sew, examine the stitches, then see if you can find a balance using the upper-tensionassembly alone.2 Nov 2008

Bottom tension is to tight on Jerome gold machine

Usually, the upper tension should work in tandem with the bobbin tension so they actually pull against each other. If the upper tension is too loose, then the bobbin tension will not be pulled up into the fabric. Try tightening the upper tension and see if that makes a difference. The two threads should meet in the middle of the fabric.

However, on occasion, the bobbin tension is, in fact, too tight and can be adjusted. Be sure to mark the setting BEFORE making any adjustments (so you can reverse your changes) and make tiny incremental adjustments to the bobbin tension, ie 1/8 to 1/4 turn. A little adjustment makes a BIG change in bobbin tension.

Do I need to adjust bobbin tension when changing stiches

Usually one does not change bobbin tension. Adjusting the tension on the needle thread is all that is required.

It is sometimes necessary to change the bobbin tension but only when changing to an extremely fine, slick thread or to a very heavy, rough thread.

How to adjust tha tension on the bobbin on kenmore model 158.13180

Hello Sharon, Remove the bobbin case from your machine. On the side of the bobbin case you will find a single slotted screw. If you want more bobbin tension, turn that screw to the right. ( clockwise ) If you want less bobbin tension, turn that screw to the left. ( counter clockwise ) When you change the bobbin tension, you may also need to adjust your needle tension to match.

Thread or bobbin tension

Thread tension. Beware of adjusting the bobbin screw. Pfaffs maintain their tensions just fine without adjusting the bobbin tension, unless you're using some crazy thick or fine thread. If you must change your bobbin tension, you would be well-advised to buy an extra bobbin case, because re-calibrating your tensions after changing them can be less than fun.

Increase your top tension, and your looping should cease. I normally keep my tension around 4.5. Also make sure you're using a good quality thread, and that there's nothing in the upper tension assemblies. Sometimes a tiny piece of debris can keep the top tension from applying enough tension, so turning the machine off and blowing some canned air in there can help as well.

Good luck,

Bobbin tension

If the looping is happening on the underside, it is your top tension that is to blame, conversely looping on top is bobbin tension.........take a look HERE for detail on cleaning lint buildup.

Top tension should be set around the middle of the range, usually 4 - 6.

I would not advise playing with bobbin tensions, however, you can take the needle plate off to clean the hook race area (where bobbin case sits) ...this is good housekeeping, my wife does this every time she replaces the bobbin....just take it out and clean the bobbin case and the fixed metal hook race with a small brush to remove lint, if there appears to be fine dirty deposits, a cloth or cotton bud (Q tip) moistened (not soaked) with methylated spirit will do the trick.
