Singer 29k Walking foot issue

[Constabulary]

this plunger knob is missing on the hand wheel of your machine

I´m also not sure if the paddle shaped spring on the lower end of the needle bar is present - please check that.

Above two parts have nothing to do with foot movement but both needed when you want a properly working machine.

You have not posted a picture of the rear side of the machine and have not answered in which direction you turn the hand wheel.

Just trying to figure issues before you start removing parts.

 

======================

 

The 180° rotation of the pulley usually is an issue when some one restored / took apart a machine and did not put it back together properly.

Yes IF the pulley is the issue it is the one you mentioned. It usually is held in place by 2 set screws and 1 tapered pin so you have to figure which side is the narrower end and hammer it out from this end. It sometimes is hard to tell so be careful if you hammer it from the wrong side it will be even tighter.

However there is also a cam inside the machine that drives the hook (basically) and one on the left side that controls the feed motion ring. So IF someone restored it / took it appart no one know if he put back on the cams the right way. So there is a lot of guessing.

Hi apologies 2 photos attached and I turn the wheel clockwise.

BTW what does the plunger do?

Many thanks

I have edited my last above post.

clockwise is correct - the plunger engages / disengages the hand wheel when winding the bobbin.

BTW - here is a parts list and manual for the 29K71 - it is very similar to the 29K58 with just some minor differences. Hope this helps.

EDIT:
Here is missing a thumb screw.

Should be this one:

Hi many thanks.

Does this mean I may have a broken/worn  part in the head? The pulley cam looks as if it has never been tampered with, neither do the 4 screws holding the head to the body!?

[Constabulary]

I think so but I only can guess - I assume the Bell Crank Lever is worn down or broke. See parts diagram in the above linked manual / parts list.

OR - there is an issue with the lifting lever.

I'm not sure If I can see it from the rear side.

The lever should stick out here (arrow 1) and should lift the part (arrow 2) when cranking the machine. Should look like in the 2nd picture (my 29K71 machine).

Hi I just popped over the workshop and when cranked no 2 bobs up and down once on one revolution by varying degrees dependent on thumb screw setting at high or low.

So to investigate the head its the 4 screws on the machine side and then remove needle and then once separated lower head to extract needle bar?

many thanks

Hi I took two photos from the side rear one where the is at rest and a further one as it is in contact and lifting and as it comes around the foot lifts, many thanks Peter

Hi Constabulary,

I have also got a seized 29k identical and I could go about removing the head on that one as albeit seized the foot and head seem to be in better condition than the one with the walking foot issues.

My only concern is if the needle bar is gummed and seized in the head but at some point I will have to take the seized one apart!! Is there anything I need to be aware of synchronisation wise when the head is removed? 

Many thanks for all your help Peter

Hi I solved the riddle of the non walking foot!!

I removed the head and I was in the process of undoing the 2 screws from the underside of the head and I noticed something embedded in the oily mass!

Its a small screw and unsure ff this had been jolted free by my removing the head or if it had just gelled in situ but this screw goes into the side of the bell crank lever and I extracted the stuck screw and then undid the further screw to release the revolving 'wing nut' portion and found that the screw from the other side of the bell crank lever was in situ but not screwed in!

So I cleaned it all and re-assembled with the 2 screws firmly screwed in and hey presto all working again!!

I do need a check spring so I have only secured the head with one screw until I can order this.

So just in case anyone else may have the same issue here are the photos:
