What goes here on a Juki 563?

What goes in this hole beside the tensioner assembly and what does it do?

Also, the bar that goes through the machine to release thread tension when the presser foot is lifted, how much movement should it have?
If Greg is reading this, I sure would like to add to my order before it ships on Monday if possible!
Thanks

Wow!  I loaded a pic from photobucket, kinda! ;D

Being a Juki LU 562 owner, and going by memory having just spent most of today sewing with my Juki LU 562, and with today being Saturday, my guess is:

nothing.

The metal frame of the Juki LU 563 is also used for other model types and on one or more of those other model types, something gets screwed up in that hole. But not on the Juki LU 563.

Any points for my answer, Greg?

Actually, it's basically the same as the Singer 111W155 (correct me if I'm wrong, Greg!!)  There's a set screw that goes there that holds the tension assembly in place.

Just enough to separate the tension discs. Sometimes, that pin is worn, so it doesn't protrude far enough.
Are you having tension problems?

I have just barely used the machine so far.  Tried it before I got it.  I just noticed that the scrap I was using didn't want to pull out to snip the thread.  I wanted to clean up the machine before using it or I may never get to it again.  It was filthy!  I just ordered a new assembly, since they are cheap, to hopefully know it's right.

I was thinking that there must be a set screw in that hole.  If not, the tension release bar would just push the lower part of the assembly since the only other screw is at the top.  I think the threads must have stripped or the cast metal chipped and the previous owner had used a cheap screw with tin foil looking stuff around it to tighten it up.  Needless to say it was a bad fix.  I guess I'll have to drill and tap for a slightly larger set screw.  The top screw has been replaced as well so I'll fix it too.

While cleaning under the machine, I found out why I was unable to adjust the stitch length.  The adjuster was sliding on the shaft and the adjustment button wouldn't  go in the slot to hold the adjuster.  The set screws were just loose.

Read this thread over the weekend but wanted to wait until I could respond in a meaningful way...

As stated, YES, there is a set screw (LU-563 is recessed with no screw head, others are protruding with a round head, of course they work all the same.  Some machines for examaple Consew 255RB has this set screw from the opposite side, throught the front arm cover.

This screw being refered to here is index # 5 in this image.

What this does not indicate is how much tension on the thread controller/tension sping we are looking for; we would set this so that this spring will 'snap' back into place under load, or under normal sewing.  We do this by flicking it by hand.  Just enough to snap back.  Too much may prematurely wear out and snap the spring.  This is a wear item, and will, over time, need to be replaced.  Machine WILL NOT work properly without this spring.

Mr. Gregg,

I beg to differ. And I also hate to think that I was wrong.

I looked at my Juki LU 562 today, and I just looked at the picture brownie posted. The hole that she has circled, on my machine, has nothing in it, as I had thought I remembered.

I believe the hole you are talking about is not the one brownie had circled.

Please don't feel the need to respond. I'm just making a mountain out of a mole hill. I'm just pole vaulting over mouse turds. I'm just really tired from a rather enjoyable day working at my studio.

I thought that hole was where the Ipod holder went.

I learn something new everyday on this forum.  ;D

Gene,

If you think you were looking at somthing different on your LU-562, check this out;

Gene,  look real close for threads in that hole.  I believe Greg is correct.

Since the threads are stripped and a small pics of the cast metal is chipped away on the inside, I plan to attempt retapping the threads.  I may have to build up the back side with JB Weld.  If that doesn't work out I'll try to drill and tap on the left side of the assembly.  If all else fails, I may just epoxy it in.  The assembly will probably outlast me anyhow!

Of course Gregg is correct! That's what he does! LOL

My grandma used to say, "Never argue with someone who knows what they are talking about." She seemed to tell me that more than the other grand-kids. Hum?

I did get down low enough to look all the way into that hole. And yes, there is a little set screw in there.

Thank you Gregg for the picture. I copied it and put it with my other papers for my juki.
