Pfaff 345 presser foot not lifting

[Mooks]

I have a Pfaff 345 that I am trying to get working. The vibrator foot works (lifts) fine, but the presser foot doesn't budge when I turn the handwheel.

I have looked at the Youtube video about adjusting the vibrator and presser feet but it hasn't made any difference.

I am trying to figure out how the mechanism is supposed to work , but so far I am hitting a brick wall.

Any advice would be greatly appreciated.

w/o knowing your machine and w/o knowing what in particular you did or have tried so far or what YT video you have watched...

there is a cam with a wing nut on the rear, when you loosen the wing nut and shove it in the upper position an tighten it again you get more foot lift.

If it does not help loosen the two screws in one of the reed circles (dose not matter which) then rotate the hand wheel until the inner foot and the needle tip arrive at the throat plate level at the same time then tighten the screws.

hope this helps.

Thanks for the reply and the helpful suggestions. After doing what you said, ( loosened the nuts and set the needle and vibrator foot to feeddog level). the presser

foot does move, but marginally. The photo labelled no.3 shows the max elevation that the presser foot makes. It clearly does not make the 7mm that I have seen

suggested.  Please let me know where I can go from here in terms of trouble shooting the issue. My machine looks very similar to the one in your photo.

Thanks again.

have you adjusted the cam?  See red arrow in my picture.

Yes, adjusted the cam, it is as high as it will go.

Hi did you get this sorted? I have the exact same thing on my new (1960) Pfaff 145 H2. I'll probably start a new thread as I have found other issues with it while restoring it. My presser foot was lifting barely 1mm until I went through all the adjustment procedures I could find in order. Now it doesn't move at all. Steve
