Members hemiyota Posted September 23 Members Report Posted September 23 I was attempting to equalize the forward and reverse stitch length, as described in the video by Ewe. Got to the point where you move the block, to either lengthen or shorten the forward stitch, and it wont move. After loosening the screw, when I try to move it, it just moves the reverse lever. Isn't it supposed to pivot on the shaft? Quote

Members hemiyota Posted September 23 Author Members Report Posted September 23 Here's the link to the video. Procedure starts at about 10:00. I'll post a pic in a bit... Quote
Members hemiyota Posted September 23 Author Members Report Posted September 23 Here's the part that should move, if I'm understanding the video correctly... Quote
Contributing Member friquant Posted September 23 Contributing Member Report Posted September 23 You could put a crescent wrench on the block to gently rotate it Quote friquant. Like a frequent, piquant flyer. Check out my blog: Choosing a Motor for your Industrial Sewing Machine
Members hemiyota Posted September 28 Author Members Report Posted September 28 I don't want to mess with it too much until I know, for sure, that it's supposed to move.... Quote
Contributing Member friquant Posted September 28 Contributing Member Report Posted September 28 Maybe post a video showing how yours moves when that screw is loosened Quote friquant. Like a frequent, piquant flyer. Check out my blog: Choosing a Motor for your Industrial Sewing Machine
MikeG Posted November 28 Report Posted November 28 (edited) I have the exact same issue with my vintage Juki LU-563. The stitch block cannot be moved because there is a roll pin adjacent to the adjusting screw. Moving to the right, I thought I could make the adjustment using the two screws marked in yellow, but no joy. I believe the only way to adjust this machine is to remove and discard the roll pin. At the present time, I have about 7 stitches/inch forward and about 4 per inch in reverse, so it definitely needs to be corrected. Hoping UWE can weigh in on this. Pic showing roll pin: Pic of Reverse bar screws: EDIT: My theory is Juki set the forward stitch length at the factory and locked it with the roll pin, with the intent of setting the reverse stitch to match using the limiters. UWE removed the stitch limit on the reverse and then adjusted the bar to get equal length stitches, with the result being a longer stitch length than came from the factory.

MikeG Posted Saturday at 01:41 PM Report Posted Saturday at 01:41 PM Update: removing the roll pin allowed for adjustment of the stitch length forward and backward and the machine now reverses into the same holes, just as in UWE's video! SUCCESS! Quote
