Bobbin Troubles

[Hi Im Joe]

Hey guys,

I cannot seem to get the hook to take up the bobbin thread. It just spins around. I've tried searching but can't really find a tutorial for the Adler 67.

Anybody have any ideas? How do I troubleshoot this?

Thanks,

Joe

I don't know anything about your machine. But do you have thread pulled out of the bobbin and the needle threaded ? I did find some stuff about your machine here https://www.google.com/search?q=Adler+67&ie=utf-8&oe=utf-8&aq=t&rls=org.mozilla:en-GB:official&client=firefox-a&channel=sb not sure if any of it will help or not.

Make sure that needle is all the way up in the needle bar and the needle scarf is showing to the right side? Have you threaded the needle from left to right? There is a small tab on the hook which should sit in the small gap of the needle plate make sure it is in the right position

If this is safe and there is no dirt, sewing dust or old thread in the hook era you should check the hook / needle timing.

The tip of the hook should meet the needle scarf approx. 1.6mm above the needle eye when the needle bar is in the upwards movement. I think this can bee seen in the video quite clear. This shows the hook of my Singer but yours should be very similar. You can also thee the small tab on the left side of the hook.

Yeah I have it threaded in the way the manual indicates.

What exactly is the scarf? Yes the needle is threaded from left to right. I think the tab you are talking about is there and in the correct position. The assembly look clean of stuff but I haven't taken it all apart to truly know. I think it seems like a timing issue. One thing though when I put the bobbin in the hook just will not grab the thread. Its turning but it just passes under the thread without ever touching it.

[Hi Im Joe]

Thank you man. You are super helpful. Fortunately, my sister in law is a seamstress so I have her coming over tonight (keeping my fingers crossed) to help me try to figure this out. I know she's never worked on "industrial" or walking foot machines but at least she has experience with other machines.

The hook does not pick up the bobbin thread, it hooks the top thread which goes around the bobbin case then it catches the bobbin thread.

HAHAHAHAHA....that's good to know. Goes to show you I know literally nothing.

Thanks for the heads up.

[Hi Im Joe]

I'm pretty sure it's a timing issue. I handcranked it through a couple cycles and the hook is missing the thread on the needle. It's already past the rotation by the time the needle comes down.

Anyone have a tutorial or a source on how to adjust the timing on the machine?

[dirtclod]

Take a look at this http://leatherworker.net/forum/index.php?showtopic=40704 they had the same problem.

[Hi Im Joe]

That's very helpful! I'm just not sure if that's my problem or not. It seems like the needle and hook will not meet up correctly. But I guess I should take some stuff apart to see if the bobbin assembly is full of junk.

I poked around a little on youtube and found this video for ya. If the guy is correct, the 267 in this video should be very similar to, if not identical to the 67 and 167, at least in the bobbin area ... That's what he said at the very end of the vid.

Between that, your German service manual, Google translate, sister-in-law, and here .. You'll get it working.

And we'll anxiously be waiting to see how creative you get with it!!

If you are not very familiar with your sewing machine, my I suggest you hold off until you have a better idea where the problem is. When my machine stops sewing correctly I stop and think about what was the last thing I adjusted or touch on the machine (i.e. changed thread, replaced needle, etc. That is where the problem lies. If the machine is new to you then go slowly and refrain from multiple changes. Don't ask me why I know this ;-) Good luck with your research...

My sister in law confirmed for me its the timing. The hook is literally 180 degrees off from where it should be. When the needle is at its lowest point the hook is on the opposite side from the needle.

btw...I don't see a video in your post.

Right now I am just focused on why the hook won't take up the thread. If I fix that issue I think I'll be good to actually sew something. Or try to sew something!

[billybopp]

OOPS. Right you are. Here's the link! http://www.youtube.com/watch?v=8pGCn0iw-50

Unfortunately it probably won't be as helpful as I hoped, but the guy does show how to re-assemble and lube the bobbin area which you will probably want to do along with the timing as well as now and then afterward. He does give us a clue, tho that timing is not set in that immediate area with this machine.

If you look at the link that dirtclod posted above, page 2, entry 2 by CowboyBob mentions a belt that can cause timing problems. That may give you a starting point and an idea what to look for in the service manual. Google translate might be helpful at that point.

Wish I could tell you more, but I don't know much more about sewing machines than you do, but I'm following a lot of the sewing machine threads so that when I do finally go that route, I'll have some info under my belt.

Hope that helps!

It also occurs to me that if timing is that far out, somebody may have disassembled things and not put it back correctly. That might be worth a check.

In the video it looks like the hook is positioned on the plate beneath by a rolled pin. That pin might be a shear pin to prevent excessive damage if something jams up, and could be broken. We used to use shear pins like that in some of the big laser printers, check sorters, and other equipment that I worked on in a former life. That might be worth a check too.

Hopefully some o' the pros will chip in on this and help you too if they're not worn out by Chinese machine questions.

I also just noticed your post from yesterday about the motor cap. Sometimes you can get by without one, but usually not. Read the markings on the capacitor it should give you the info that you need to get a replacement. It'll be marked with some voltage (VAC) and some capacitance, probably in the uf or mf range. A good source for motor caps is http://www.grainger.com/category/category/capacitors/motor-supplies/motors/ecatalog/N-9yp?redirect=capacitor

Hope that helps

[Hi Im Joe]

So I got lucky! My father in-law is an aircraft assembler for GE. A co-worker of his rebuilds and services sewing machines as a hobby. Its a small world. He is going to come over and check things out for me. So now all I gotta do is wait.

As far as the capacitor...I ended up re-wiring most of the electric as it was old and ratty. So it should be good. "Should"
