Jacktheboatguy Report post Posted December 11, 2022 I'm using a Juki LU562 for boat upholstery work & it's been working great until now. I had a major birds nest that took quite a while to clear - probably due to operator error on putting in a new bobbin. Now I get a major jam trying to thread it & the machine locks up (probably the safety clutch). I secretly violated the 'guy code' & read the manual. It looks like my bobbin mechanism has rotated about 45° CCW.The manual shows (& it's always been the case) that the 'protuberance' "A" is right next to the point of the arm "B" - touching it & not touching it as the bobbin rotates. Now they're separated by almost 45°. Does that seem like a good observation? Is this something a reasonably handy person could fix? There's a bit of vague adjustment info on pages 18 & 19 but I'm not sure this addresses what I need. There is a good shop in Indianapolis but he's always backed up - taking it there is sort of a last resort. Any recommendations or advice? Quote Share this post Link to post Share on other sites
Jacktheboatguy Report post Posted December 11, 2022 There is a great YouTube video explaining exactly how I assembled the cover plate incorrectly & caused my own problem. Working fine now. Thanks to anyone who pondered how to explain something so simple to me! Jack Quote Share this post Link to post Share on other sites
Constabulary Report post Posted December 11, 2022 (edited) The bobbin case tab has to sit in the notch of the needle plate - see tips of the arrow. Remove the needle plate screws, rotate the bobbin case and put back on the needle plate. EDIT: Looks like you figured it Edited December 11, 2022 by Constabulary Quote Share this post Link to post Share on other sites
