    I have the singer 758 and the thread is not catching the bobbin thread.  The hook moves but doesn't catch the thread.

When you turn the handwheel, does the hook move? If not the top gear on the vertical shaft is stripped and needs to be replaced.

I have recently bought Singer Quantum 9940 and I am not happy with the stitch. For zigzag stitch, I can see too much of the upper thread on the bottom side. This happens unequally: more on the right hand...


1. Make sure your needle is correct for the fabric. Go buy some good needles in several sizes. You'll need a 90 for jeans, rounded points for fine fabrics... get a few sizes. Your manual should provided you with clues to the right needle for the fabrics. (BTW... there really is no such thing as a Universal Needle... toss it.)

2. Re-read your manual and carefully follow the instructions on threading the bobbin and the upper thread...

3. Check your tension on the upper thread... it is too loose for the application. The tension on the bottom thread is handled by a spring on your bobbin case or race. If you do not have that threaded properly you'll have problems. Same with the direction the bobbin turns... have in it backwards... problems.

Barring all these things... It might be time for a qualified Singer repair person to look at it. Sadly Singer has seriously lowered it's standards in the last 20 years.

My singer 9005 wont sew. I threaded everything correct. but it wont sew two pieces together at all. I think its bobber prroblems, as it takes a while for me to thread it through.


If, you do not have your manual, go to www.singerco.com and download one for free. Click on customer support and instruction manual then 9005, You can enlarge your diagrams for threading etc, save the manual on your computer besides printing it out. I am hoping it is not your timing because that is not a diy job, you need special tools and expertise to do it. Good luck

The needle hits the plate and doesn't go down to grab the bobbin thread reguardles of the needle position.


Sounds like a timing issue, Unfortunately it is not a do it yourself job. You need special tools and the training to do it right. Sorry, but you are going to have it serviced.
