Hi all.
Thanks for letting me join. I have read many posts on this site and have been very impressed with how helpful everyone is, and the awesome projects I have seen.
I have had my Juki LU-563 for a few years, but just now started to use it. After much work on adjusting, cleaning and fixing things, it seems the gap between the bobbin case catch tab, and the foot plate does not have large enough gap for the thread to pass between easily (I measured .18 should be .40 per an engineering manual I found). I also believe the top of the bobbin is too close to the other cover/plate to allow the thread to pass over it well either.
Well after reading many posts , and watching many videos over the last week, I have learned a lot! I corrected the top threading route so not be around the tension disc pin, took apart and cleaned the tension discs, I know for sure how the needle goes in, how close the hook should be to the needle, timing, oiled everything, cleaned many things.
I took the hook out and it looks to me like the brass bushing should be lower about .5mm the amount I need to make the 1mm(.40) gap at the tab/plate area. I took the hook out, loosed the bushing set screws and gave it a few taps to drive it down, but no change.
If the bushing #6 won't move, then would I need to remove or replace with a thinner #25 thrust washer? I am afraid to let the gear #22 slip out as I understand it is hard to get back in? I did mark it and the drive gear #20 with nail polish to match up teeth should something happen. The rod between the hook and bobbin case lever #5 even sits high above #8 about the amount I need it to move down. However #5 seems to set flush on top of the bushing #6 just fine.
Anyone else have this issue too? Thanks.
