I have a PC8200 Pacesetter and I can't seem to use the self-threading needle because ir won't catch the thread and bring it through the needle eye. Its so small that its hard to see but perhaps there is a small part broken off. Can I get a replacement threader attachment?

Be sure to install a brand new needle--check that the needle eye is the correct size for the thread you are using--a small needle eye will shred heavy thread. It may also help to remove the top thread from the machine, ALWAYS RAISE the presser foot and rethread from the beginning. Verify the thread path is correct. Try different thread--AVOID old or bargain bin thread. Check that the upper tension is not too tight.

If the top does not pick up the bobbin thread, the machine may be out of time.

Otherwise, there may be a burr or snag somewhere along the thread path that is catching and fraying the thread. Sometimes there is a snag in the bobbin area (possibly the needle plate or hook) that is rubbing the thread.

What Causes My Thread to Shred

Fraying Breaking Madeira

Could be a multitude of things. Use only good quality thread--no old or bargain bin threads. Try a different brand of thread--some machines prefer certain brands over others. The needle and thread should be compatible--ie needle eye shouldn't be too small for thread weight. Burr catching the thread and breaking it. Upper tension too tight.

Remove the upper thread, RAISE the presser foot and rethread from the beginning. Verify the thread is not looped incorrectly in the thread path, like around a thread guide or around the spool pin. Is the thread snagging on the thread spool itself? Do you see the thread tightening as you sew and eventually it breaks? This indicates it is catching somewhere between the needle and spool. Is it shredding at the needle eye? This indicates the needle eye is not suitable for the thread being used.

Watch where the thread is breaking. This will sometimes give you a clue where the problem exists.

Why Does My Thread Keep Breaking While Sew

All About Needles

Pull at least 6" of thread through the needle's eye and gently holding both thread tails gently when beginning to sew. Might try installing a brand new needle--make sure it is installed correctly. Raise the presser foot BEFORE threading the upper thread.

The first thing to always try is installing a brand new needle.

If it is actually pulling the thread out of the needle, try pulling at least six inches of thread through the needle's eye and the bobbin before beginning to stitch. This may be helpful:
How and Why to Bring up the Bobbin Thread

Is the thread actually breaking after the first stitches are taken? If so, the tension is too tight or the machine is threaded incorrectly. Check your owner's manual and be sure you are threading everything correctly. When threading the upper thread, FIRST RAISE the presser foot so the thread will seat properly in the upper tension disk.

Thread will also break if the thread is not correct for the needle, ie it is too big for the needle's eye. The following web site may be helpful in selecting the correct needle for your project:
All About Needles

The upper thread may also break if there is a burr or knick somewhere in the bobbin area that is catching the thread.

...

Check the spindle the thread is mounted on and see if it\'s wrapped around it. Sometimes thread will catch and wrap around the spool spindle and break.

Check thread guides to be sure there are no nicks that might be catching the thread or damaging it.



Replace the needle.. a burr in the eye can cause upper thread to break. Needles should be replaced often, modern fibres can be hard on them, they get dull and that\'s no help for anything either.



Make sure the thread spool is mounted on the spindle with the thread coming off as directed in the manual. Some machines only work when the thread feeds in the right direction from the spool.



It can also be a tension issue.. tight upper tension or tight bobbin tension. Bobbin tension may be adjustable manually, but it\'s pretty rare for it be a problem. Upper tension, I don\'t know. I\'ve yet to get into computer machines so am not familiar with how they set upper tension.



But the mechanism that produces the tension can wear out or break and need replacement.

this could be a couple of things, all relating to threading up, your thread is either catching on something in the threading path, or missing a thread eye in the threading path, or most likely, the thread take up lever is not threaded up.

make sure the needle is inserted correctly into the needle holder

try changing the needle
also rethread the machine
clean under the needle plate & in the bobbin area for loose threads or lint
if these suggestions don't help the it's possible that the machine has jumped time & needs to be serviced

The bobbin is held in a removable bobbin case. If the bobbin case is already out of the machine, place the bobbin in the bobbin case such that the thread will come off clockwise. Leave a couple of inches of thread loose. Then pull the end of the thread down into the cross slot and thread it through the tension spring and into the delivery eye.

Next make sure the presser foot is up and the needle is in the highest position. Push the slide plate up. Hold the latch in the center of the bobbin case and place it over the center stud with the finger opposite the notch in the shuttle race. Release the latch in the center and press down on the bobbin case until you hear a click when the latch catches the groove. Leave a 2-3" length of thread extending out of the bobbin case and push the slide plate down. (Reverse the steps to remove the bobbin case.)

To thread the needle, place a spool on the spool pin with the needle bar fully up. I try to place the spool on the pin so that the little catch is out of the way. (The catch holds the end of the thread when the spool isn't in use.) Bring the thread through the guide loop on the top of the machine and then down through the thread guide on the right side of the tension discs. Bring the thread back up on the left side of the tension discs through the check spring and through the thread guide. Bring the thread through the hole (eye) in the take up lever (from right to left). Then bring the thread down through all of the guides down the face of the machine to the needle. Finally thread the needle from left to right. Pull a few inches of thread through the needle. (I find the threading of the needle to be easiest if the thread has been cut at an angle after threading the machine.)

The manual for the White 765 is available from Singer's support site. The direct link to the manual is http://www.singerco.com/uploads/download/827_white-765-x.pdf . See page 6 of the manual and the subsequent pages for pictures.

I hope this helps.

try lowering it so that it meets the eye of the needle, I had to do that on one of my machines, just pull it down a little.
