I broke a needle on heavy fabric, I replaced the needle and the machine would not pick up the bobbin thread. I have THOROUGHLY checked and replaced the needle, needle placement, bobbin and bobbin placement, threading of needle, and removed all dust. I have done ALL the basic testing cycles. As I stated previously, my research into this matter (and the ONLY reason I paid for technical information) has indicated that the problem could be needle bar timing...it could have been knocked out of timing when the first needle was broken. Please, tell me how to correct the needle bar timing on my machine. I live appx 65 miles from the nearest repair shop and need to get this problem resolved. I have now spent 3 days going back and forth with this same question only to be told every time to check my needle and bobbin. Please believe me, I HAVE.

I had the exact same problem. The timing is off. You can actually fix this yourself all you need is an allen wrench. If you look at the rod the needle is inserted into and follow it up to about 2 inches below the top of the machine there should be a clamp. use the allan wrench to loosen the clamp and adjust the needle height. I used this website as a guide to getting the timing correct. http://www.sewusa.com/Sewing_Machine_Repair/Repair_Pictures/timing1.gif

now if only I could figure out why my thread keeps getting jammed under the bobbin!

Try flipping the bobbin spool so the thread comes off in the other direction.
Forcing means that the needle has been jammed against the sewing plate ant the needle is now out of timing with the bobbin pickup.

1. Make sure the needle is up in the machine all the way.
2. Make sure the flat side of the needle is facing the rear of the machine
3. Only turn the handwheel on the side of the machine towards you, never away from you.
4.Double check your threading of the top of the machine.
5. Also make sure your using the proper needle, your machine takes the most common needle on the market but some look like it and are shorter or longer and wont work properly. Also make sure your not buying needles for a singer serger.

Make sure that you have the needle's flat side facing the rear of the machine, or else it will never grab the thread. Also, make sure you hold the top thread in your left hand until it grabs the thread and you pull the bobbin thread up
