Help with a Juki 562

[Gregg From Keystone Sewing]

Juki offers a various size thrust washers, see the chart for reference.  HOWEVER, standard is 1.3mm, and thinnest is 1mm.  I really doubt this is going to get it to where we want it, but I would check the thrust washer thickness to make sure it's not way out of bounds.

Another way to fix this 'out in the field' is to jamb something between the hook saddle and bed frame to bring this hook lower.  Plastic from a milk carton comes to mind.  You would not be the first or the last person to fix a machine of this type like this.

This is a puzzle. I suppose, that when you find the problem it is quite simple. But now it is hard, and it has been so for some time.

I just like to ask this question. What prevents the new hook assembly to go further down as it should? Are you able to put in small strips of paper or thread to feel where this hook assembly is stopped in its movement downwards?

I'm so looking forward to finding the "easy" solution....

Yes, the hook assembly rests on the top of the thrust washer with or without the "opening lever crank" installed.

I flipped the washer and "shimmed" the saddle, seems like plenty of clearance now.  Just need to get my calipers back from a friend.  I'm going to try and time the machine and see how it does.  Thanks for the input!!
