Singer 111W155 Alternating Presser Foot Problem

[Wishful]

Not sure what I did exactly but while cleaning and oiling my machine, the rear presser foot is not lowering even though the lever is down. It is also not moving when I run the machine. I did not intentionally change anything but must have. Would it be the presser bar spring or knee lift lever? Any ideas? I appreciate any leads.

This would be my 1st idea.

Check the parts 1.), 2.) and 3.) in the picture if their screws are loose and check if part 1.) is moving when you lift the foot lever and check is parts 2.) + 3.) are moving when you turn the hand wheel. Screws for the parts are all accessible from the backside.

I assume screw of part 1.) is loose. But it can´t be wrong to check them all.

2nd idea,There's a vertical rod for the knee lifter on the back that if you tilted the machine back & set it back down could of gotten in a bind.

Thanks for the input guys, and the pix. The knee lifter seems fine, as does items 1 is loose. 2 and 3 are not moving , maybe that is it. I cannot turn screw 2 yet. Should they be loose or tight?

You may need to apply penetrating oil to loosen the grip of the screws. They are normally tight, but not so much that they can't be unscrewed when necessary.

So with other words the presser foot is stuck in its position, right?

Then before you loose the screws on part 1.) + 2.) check the part that looks like a fork and part 3.) is sitting in.

The part is secured with a small screw from the backside. Loose the screw a 1/2 turn and try to adjust the "fork part" with a screw driver from the top side. The part has a slit.

I had this problem with my Duerkopp 252 and a small adjustment on the fork part did the job.

A thoroughly oiling could be useful as well.

Working on loosening the screw with liquid wrench. You are correct that the presser foot is stuck in the position. Does the presser foot eccentric play a role in the movement? If so how?

I looked closer at your picture and compared it with my machine with foot in lift up position.

At your machine the part I numbered with 3.) seems to be quite far up in the fork when the foot is lift.

At my machine it is in a much lower position even when foot is lifted. See pictures below

Try to put flat screwdriver between the parts, use it as a lever and try to push down part 3.)

I assume the fork part is too tight and the part 3.) is stuck there.

[Wishful]

You are correct, I was able to loosen the upper screw and lower the shaft a bit but it is very tight which I assume is due to the lower screw. I planned on taking it to someone but they are tied up until after Christmas so I figured I would fuss with it until then. I downloaded the navy manual and will try to disassemble and reassemble to figure out whats up. it seems to me something has seized but I'm stumped. I appreciate you pix and ideas. Im trying to identify what actually moves that presser foot up and down during sewing

i am having this same problem with my 111w155 i can lift the presser bar up with the lever but it doesnt actuate from the cams movement from the back of machine and all connections are tight.

I am new to this forum and have seen this touched on in different ways but cant find the reason for this problem in past posts.I also know this is an older post
