Question about Sewing Machines
When bobbin case is out, I see that the inner part of where it normally snaps in, spins around, and blocks the spot where the needle is to come
cleanly down and back up with the thread from the bobbin. Is this a timing problem? Can I fix this myself? I have a Pfaff 332 sewing machine.
I believe that the bobbin case holder has become unlatched, for lack of better terminology. I have one of these machines, and my first experience with one was exactly as you are describing. A friends grandmother brought it to me because it kept breaking needles and wouldn't complete a stitch.Put the bed table in the lowered position, leaving the free arm exposed. Remove your needle, presser foot, and bobbin case, leaving the bobbin door open. Next remove the two screws that hold in the feed plate, and remove the feed plate. Looking down into the bobbin area, manually turn the bobbin case holder. There is a small slot in the top of the bobbin case holder, look for it as you turn. A small latch protruding from the bed plate is supposed to be clipped into that slot, and if the latch is still there, you likely will not be able to rotate the holder into place: This is good news, it means nothing is broken. Loosen the three screws (two silver on the top of the bed plate and one black in the area where the feed plate goes) which hold the bed plate in place, but do not remove them. You should be able to lift the bed enough to get the holder into place, and then set the bed back down and tighten the screws. Reassemble everything, throw in a new needle and see how it goes!

Hi - it is possible that your needle is bent. Insert a new needle and check again - if you have the same problem, your timing is probably off. You could try buying a new bobbin case to see if that solves the problem. If you have had your machine tuned up within the last year or two, I would recommend a tune-up. If you know of a reputable sewing machine repair shop or dealer, the tune up should include correcting the timing and will extend the life of your machine.

There are two parts to the sew hook on that machine. The outer part has the hook point that grabs the thread off the needle. Then there is an inner part which has a post in the center of it that the bobbin case fits on to. The inner part should be held in place with an arm that has a bump on it. It keeps the inner part from spinning around. Sometimes this arm slips loose and a notch in the inner part of the hook assembly slips out from under the knob on the arm. If this is what is happening, you need to loosen the screw holding the arm in place and reposition the notch of the inner part of the hook back under the bump on the arm. There needs to be clearance between the notch and the bump for the thread to pass between the two. And the bump should be in line with the needle when it is in its lowest position.
If this doesn't solve the problem you need to take the machine in for repair.
