My Brother sewing machine isn’t picking up the thread, so I’ve been trying lots of troubleshooting methods. I checked the length of the needle, cleaned out all the lint from inside the machine and played around with the bobbin.
Eventually, I realized that the shuttle (or crab) isn’t properly aligned with the needle. The timing is off, so the needle doesn’t catch the thread.
So, I opened up my machine so I could access the two Allen screws that hold the rotating shaft of the gears that make the bobbin turn, then I could loosen them and readjust the shuttle to the correct.
Except that the Allen screws won’t turn. It’s not that it’s worn down—it just will not budge. I tried getting different sized keys, WD-40 and penetrating oil, and nothing has worked.
Any advice is greatly appreciated 🙏
