SOURCE: Bobbin Case Assembly

Careful now, don't get in too big of a hurry.
The back side of the hook cover, which holds the hook in place in this machine is supposed to have several grooves in it. If there are no cracks, it's probably ok. The hook should also have a considerable amount of movement, or clearance when the cover is in place. Take that away and it won't sew at all.
The most common noise I hear in these machines is a buzzing or moaning sound from the bobbin area. If this could be an apt description of your sound, remove the bobbin case, roll a cotton swab between your fingers until it will fit inside the center post of the bobbin case and clean it out with alcohol. Allow it to dry completely and then put one drop of machine oil inside this post, place it in the machine and run it. The sound should be gone.

SOURCE: shuttle alignment and assembly

The shuttle/race/bobbin system shouldn't really be taken apart by the average user. Unfortunately, your chances of ever getting it back together properly so the machine will sew (this is the timing of the machine) are very slim. You'll need to take it to a sewing machine technician. I would recommend an authorized Pfaff tech as they'll be sure to have the proper tools to do this correctly - won't be inexpensive but will be worth it. Most "neighborhood sewing machine repair folks" don't have experience on computer machines. Resetting timing on a computer machine isn't the same as the old mechanicals and requires some expertise.

SOURCE: designer 1 bobbin assembly loose

If the bobbin winder spindle is loose and flopping around in the opening in the front of the machine is has come out of the frame that it should be mounted in. Operating the machine with loose parts inside can be risky for the machine and the operator.
Don't take a chance on causing further damage to the machine. The bobbin winder can be replaced without too much trouble and is relatively inexpensive.

SOURCE: Installing the hook and bobbin assembly.

The plastic bobbin case should sit on top of the raceway, it should slot in quite easily, once the bobbin case is in put the small metal clip at the top over to hold it in place.

Industrial sewing machine has jammed, the wheel will not turn


Hello Christine, I think you do have a thread stuck between the rotary hook and the bobbin case carrier. Remove the bobbin case and bobbin. You will need to remove two small slotted head screws and remove the half circle locking ring that holds the bobbin case carrier in place. Try to wiggle the bobbin case carrier one way and than the other until it comes out of the rotary hook assembly. Don't pry too hard or you might damage the carrier and/or rotary hook assembly. Once removed, I think you will find the thread that is causing the lock up situation . Before reassembling, place a drop of oil on the bearing surfaces between the carrier and rotary hook assembly and also between the locking ring and the carrier.

Loose top thread bernina 1008, tension problem but no solutions yet...


Are you sure you are getting the top thread between the tension discs? You should be able to tell the difference when you lower the pressed foot.

Release the hand wheel and wind the bobbin as full as you like or until it stops. Remove the bobbin,place it in the bobbin case and insert the bobbincase into the hook.

Beginning with the spool, guide the thread through the thread guides to the tension assembly. Pull the thread through the tension assembly and test it to make sure the tension is working correctly.
(To do this test, adjust your tension setting to normal or medium or 5 or something in the middle. Raise the presser foot and pull the thread through the tension. It should pull easily!! Lower the presser foot and pull the thread. It should pull noticeably harder.) If it passes this test, continue up through the take up lever,then down through the thread guides to the needle. Make sure your needle is fully inserted and turned the correct way.( If you load your bobbin case from the left side,the needle rule is normally FLAT to the RIGHT is RIGHT. There are some exceptions. If you have a newer style drop in bobbin or your bobbin case loads in the front then the rule is FLAT to the BACK.

How can I get the case of my Singer Featherweight II open?


To remove the cover of the Singer model 117 Featherweight II sewing machine:

Referring to the diagram below:
hronbo.jpg
1.Remove the face plate by removing the single screw fastening it to the left end of the chassis.

2.
To make things easier, remove the presser foot (raise the presser foot and release the presser foot from its holder by pressing the black plastic foot release found at the rear of the foot holder, the foot will fall off.)

3.Remove the plastic see-thru slide plate that covers the bobbin. Remove the bobbin, and remove the two screws that secure the needle plate.Lift off the needle plate.Don't mess with the feed dog screws( Look closely at the" bobbin case assembly" and note how it is installed. The black thing you are looking at is the assembly. The chrome thing that looks like a hook is a fixed "bobbin case stop plate" , the case assembly fits under that and is supported by the hook race. Approximately 180 degrees from the fixed stop is a spring stop- note that the bobbin case assembly is free to rotate/ wiggle approximately 1/8" between these two points, and it is seated evenly in the hook race.Remember what you see so you can reinstall it later)Remove the bobbin case assembly with your fingers.

4.Remove the detachable tool case from the front of the machine by sliding it to the left.

5.The face cover is fastened to the chassis with four screws- two on the bottom which also pass through the bottom of the rear cover, one behind the face plate just above the lower thread guide, and one on the front of the machine behind the tool case. Remove the screws on the front and the left end, and loosen the two screws on the bottom ( if you are planning to remove the rear cover go ahead and remove the bottom screws completely.) There is no need to remove the screws that hold the auxiliary leg bar.

6.The screws are out- HOW DO I GET THE COVER OFF!?!
There is a hidden locking tab located just beneath the mylar seal that warns you to disconnect the machine before servicing and to close the cover before operating the machine. It is located just to the right of the needle plate and directly over the seam that separates the front and back covers. Don't remove the seal just slice it with a razor blade or utility knife right along the seam, make sure you cut all the way through the seal.

Working from the needle plate opening, take a medium sized flat-bladed screw driver and slide it under the rear cover just behind the seam (see photo) carefully twist the blade in a manner that both separates and lifts the rear cover off the front cover- it takes quite a bit of force and it will let loose with a loud snap. After the locking tab is loose the front cover is easily separated and lifted off the chassis.

unlocking the case:

a closeup of the tab on the front cover

7.The rear cover is held on by three screws. There is one through the back at the handle recess, and there are two screws accessible from the front after the front cover is removed. Lower the presser foot lever, pull the screws and the rear cover will come off easy. Good luck with your repairs.

Tension


I'm assuming the thread is looping on the bottom. If this is not the case, ignore the rest of this.
Perform a tension test. Tension assembly test. To do this test. Pull the thread through the tension assembly and test it to make sure the tension is working correctly.
(To do this test, adjust your tension setting to normal or medium or 5 or something in the middle. Raise the presser foot and pull the thread through the tension. It should pull easily!! Lower the presser foot and pull the thread. It should pull noticeably harder.)
If it doesn’t work this way then you probably have a piece of thread or lint stuck inside the tension discs. To remove it, turn the tension to 0 zero and raise the presser foot.Using a small screwdriver, open the space between the discs and spray with canned or compressed air. The stuff should come out. Do the tension test again to make sure you got everything and then try sewing again.

Thread breaking.


Rethread the machine following these directions:
all machines thread the same. TTN tension, take up, needle.
Beginning with the spool, guide the thread through the thread guides to the tension assembly. Pull the thread through the tension assembly and test it to make sure the tension is working correctly.
(To do this test, adjust your tension setting to normal or medium or 5 or something in the middle. Raise the presser foot and pull the thread through the tension. It should pull easily!! Lower the presser foot and pull the thread. It should pull noticeably harder.) If it passes this test, continue up through the take up lever,then down through the thread guides to the needle.

If you have a newer style drop in bobbin or your bobbin case loads in the front then the rule is FLAT to the BACK.
Remove the bobbin case and bobbin. Pull on the bobbin thread to make sure it doesn't pull too hard. It should have some tension on it but not a lot. Insert the bobbin and bobbin case into the hook assembly and pull on the bobbin thread again.The tension should still be about the same. If it is tight, you need to look at the bottom of the pin that the bobbin case sits on and see if there are any threads looped around it. If there are , you need to remove them.
Hold the top thread , turn the hand wheel and see if the thread is catching someplace around the hook assembly. If it pulls the thread up easily, put some fabric in it and see how it works.
Make sure the thread is through the take up lever.
