Shaft lifter or ankle part that attaches the presser feet has broken need new one or how to fix broken one

If the presser foot isn't connected to the presser foot shank, place the foot under the center of the shank. Lower the presser foot lifter making sure that the shank goes over the presser foot pin. Press down firmly on the screw that holds the presser foot shank until you hear the foot snap into the shank. Do not turn the presser foot shank screw. See the pictures on page 9 of the manual (page 11 of the PDF). Manuals LIb has this page here https://www.manualslib.com/manual/470415/Singer-7033.html?page=11#manual . The manual is also available from Singer on their support page: https://www.singer.com/support . The direct link to the manual is https://www.singer.com/sites/default/files/product_manual/SINGER%207029_7033_%207035%20and%209410%20Sewing%20Machine.pdf . For feet that are attached to the slant shank, you loosen the presser foot shank screw. Place the shank over the presser foot screw and then tighten the screw to hold the presser foot. If you removed a foot and the shank together, put it back on. Make sure that the needle and the presser foot lifter are in their highest positions. Push up the front side (toe) of the presser foot until the foot snaps off the shank.

If the presser foot doesn't snap into place, make sure that you have everything aligned properly. Otherwise check for damage to the presser foot and the shank. Replace any damaged parts. Some presser feet are available here: https://www.sewingpartsonline.com/singer-7033-sewing-machine-parts.aspx .

I hope this helps.

It is most likely the presser foot you are trying to install was not made for your machine. There are so many machines available and most of those machines have their own presser feet, which are not interchangeable. Unfortunately, even a Singer presser foot is not interchangeable with other Singers. Some have screw attachments, others have lever attachments, some have long shanks, others have short, some are straight, others are slanted. You need to figure out what style presser foot your machine takes and then search for either the presser feet that fit or a shank adapter that you can then use snap-on feet (kits are available on eBay).

could be a sensor or computer problem,, you may need to have it serviced

The walking foot has a spring loaded lever that rides on the needle clamp screw. If you lower the needle into the hole on the walking foot it will remove the pressure and make it easier to attach the walking foot to the ankle.

Look for a presser foot "adapter" for your sewing machine. You may even find something on eBay that will work. The other option is to look for a snap-on kit for your particular machine--even though you are getting a kit, the cost may be less than looking for an adapter for your machine.

I am not too sure of what you mean by the ankle, do you mean the part that holds the foot on? That is called a presser foot holder, that only screws on. You can call Brother at 1-877-276-8437 and order from them or go to www.sewingpartsonline.com and order that part plus 10 attachments for $24.50 that is a pretty good deal actually, because yours didn't come with many extra feet. If, you decide to do that search for "presser foot holder" and the click Brother, but you have a low shank and Singer will also work. Good luck

You can purchase that shank here:

It sounds as though you are missing the ankle which is the part the foot attaches to. The ankle attaches to the metal rod with a screw and the foot snaps onto the ankle.

I have seen these machines with broken presser bar clamps (something inside the head). If it is just a bind then some oil on the presser bar may work, if the clamp is broken then it is probably not worth fixing.
Good luck!

This may be a lubrication problem on the presser foot shaft. Try freeing up with penetrating oil or Triflow. After letting set for an hour lower the presser foot and pull down on the ankle. If that does not work you need to open the machine and loosen the clamp screw on the presser foot shaft. Then try to twist the shaft to loosen it up.
