I just looked at mine this morning before I left the house. Sure enough its flopping around, I thought it was suppose to do that why else would it be a link? - HAHA. - So I will see how to get that apart tonight and re-pin it.  What else am I taking for granted?  Once you have yours back up and working take another video so I can see how much play its suppose to move.

I am taking it apart.  I do have the screw and bolt for that lower section.  I just pulled it so I could see how much play was in the upper part. I'm not sure what's up with that roller scew, I have a replacement.  I'm still looking for that internal shaft part.  I have one that is broken and one that looks like it has been welded to one end.

Now that I am aware of this linkage, I'm surprised it just pins at each end? Why didn't they just use a set screws?

Thrash threasure: Please post som pictures of the Adler 20 you are restoring! Id love to see what you've got going on. 

On a side note, the hole in the shaft is very clean and not worn at all on mine. It was just a broken pin and the break was so clean I could barely make out the pin from the shaft when I took it apart. 

Yetibell, I have fixed it with a temporary pin for now and there is no play at all, what so ever in the linkage.

I'm glad you're able to fix it without having to ream and fit - it's just more stuff to have to buy, and more work to do :wacko:

I'll see about some photos - I only work on it in fits and starts, and it's still got a ways to go - I'm just spread too thin, I guess.

I agree with Yetibell - The pinned arm doesn't seem like all that secure of a connection, for such a heavy duty machine, and the Adler is even more massive than the 7-33. But it is what it is, and you just have to try and do the best repair you can.

So looking at the parts for this back assembly (I think I forgot one screw set) but I am close, I am trying to figure out the correct angle they need to be at.  So does it go back together with them up and down, or to they have a little angle to them .  See my rough diagram below. So the red circle would be the center.

Also when you put this all back on - what position should the cam be at when you set it?  I notice when I tighten that cam ring 11486 that connects to the top arm 58578, it all stops working so I must be doing something wrong.  So what are the steps to "zero this in"?

Here is my Adler 20 - I have not started on this machine yet.  It looks like the head was rebuilt with Singer parts.

Yetibelle: What subclass is that Adler? I have the Adler 20-7 as well and it's massive, quite a lot bigger compared to the 7-33. My 20-7 has a SIMANCO shuttle race amongst other parts so I guess they're fairly similar in some aspects and I've also seen pictures of a Singer 7-class that is fairly similar in appearance to the 20-7. 

For my 7-33, they're more or less in line. Gregg linked me this as an alternative solution in case the rocking shaft I had wasnt repairable. http://store.keysew.com/catalog/product/95106499cbd74198a77839493fb3924e Not sure if it will fit yours, but it might be indicative of the angle between the two arms.

Well that Adler doesn't have a class plate one it.  It is the same size as the 7-31 so I narrowed it down to a 20-200.  But with Singer head parts.  

I will take another look at the rocker shaft but it looks like when they drilled the peg hole it's at a slight angle facing out when you line up the pin.  If you have a picture of yours restored that may help. Then I can see the correct angle. 

Thanks for the link.

OK - I guess this is Adler show and tell, now -

Here's a couple photos of my Adler 20 -19

I believe I'm the third owner - The original owner bought it NEW, and used it to sew hair-on buffalo robes - It still had some brown fur caught up in the innards  :)

The second owner couldn't deal with it at all, and just parked it in a shed - and so now it's mine.

The little light on it is interesting - The vintage woodworking machine people refer to those as "retirement lights" - They were made by Delta Machinery, for use on their drill presses and band saws - I've seen them go for $100+ on Ebay

This is where I'm at with it - Actually a little further on than when this shot was taken - I've since cleaned and painted the handwheel, and polished the rim, and cleaned and re-furbed most of the parts - It's painted with Rustoleum "Verde Green" hammertone paint - I was hoping it would come out a little more "hammered" looking, but at least it's clean and shiny, now .

As far as I can tell, the parts (good or bad) on it are all Adler - No Singer swaps - But I'm no expert, and if something wasn't marked, I couldn't necessarily tell, just by looking ..........

Here is where I'm thinking to go with it - This is a German military issue Adler, on it's special stand. I have pretty limited space in the shop, and being so compact, this could work out very well, with some good casters - It's also pretty cool looking B)
