Singer 153k103 stitch length adjustment

[ljk]

I've had 2 of those, one my first upholstery machine and 30 years later picked up at a auction for a few bucks. I used on the bike circuit, was great because I could see very well what I was doing. Here's what I did. Bought a narrow Teflon foot, got a narrow feed dog to match, set tension moderately. Good machine until you can afford a 206rb.

It’s a great machine, if I could figure out the stitch length issue it’ll be my golden goose!

Ok,if they both are all the way in try raising the feed dog so it can lift the leather off the plate,also check that feed dog doesn't have any play in it by pushing it front to back,try the needlebar too,sometimes parts in the feed system get loose & need to be tightened or replaced.

Would those things get in the way of the stitch length adjustment?

So I do have the set screw and spring, I’m confused where you speak of the spindle I hope this photo is the the spindle. I can see some threads on the tip but it looks pretty flat. I’ve heard of people grabbing a dremel using that to get the spindle right. I’m just not sure if I’d be sanding it down 

 

Yes that is the spindle. But don´t mess the tip with a Dremel. What you see on the tip are traces of part # 13066 that pushes against the tip when changing the stitch length.

Not sure if you got me right. There is a short coarse thread on the end of the top shaft (red circle) and there is a small pin inside the knob of the spindle (red arrow). And this little pin has to follow the thread when you turn the knob for changing the stitch length.

Looks like a broken pin to me, the threads at the end of the top shaft look good. So this pin must be the culprit. Looks like a tedious piece to replace. Would you just recommend replacing the whole knob itself?

The broken pin is the problem as it seems. I´m not sure if you can replace the pin, the knob may be hardened. And I do not know if the spindles are still available. I have one but I´m in Germany and it is from a Singer 111 machine not sure if the stitch numbers are the same.

Anyway, I would check with Bob Kovar from Toledo Sewing Machines. He replied in this thread as CowboyBob (see above). He may have some old stock parts. If he has none we maybe can talk.

Okay cool! I’ll shoot him a message. Hopefully I can figure this out. I’m okay with the stitch setting it has right now but would like to get longer stitches for decorative stitching. Will shoot Bob a message thank you for clearing all of this up for me and narrowing down the issue.

Haven’t figured it out yet

just yesterday I looked at the spindle on my Singer 108w and it looked like the pin is replaceable. I cross checked another 153w pats list and pound the pin as spare.

Parts # is 202443

And I found it online:

I would drill the pin out and replace it with a roll pin cut to length the roll pins are hardened.
