Members mixmkr Posted January 3, 2017 Members Report Posted January 3, 2017 As noted in the pictures.....what does this set screw do? ...and is it related to the little pin that is suppose to plunge out and open the disks on the upper tension guide? Asking because the screw seems to have no effect and my upper tension isn't releasing at times, like I'm believing it should... like with the presser feet up, etc. Quote JUKI LU562, Singer 107 W1, Thompson PW201 mini walker, a couple of plastic fantastics for light duty "home stuff".... ya know...fixin' and altering clothes.....
Uwe Posted January 3, 2017 Report Posted January 3, 2017 (edited) Rule #1 of sewing machines: don't turn a screw unless you know what it does The first screw in your picture holds the check spring stud assembly (and the whole tension unit) in place. If you loosen it you can adjust the check spring tension. But it's really a set/lock screw, not an adjustment screw. (By the way, in your first picture the thread isn't pulled between the tension discs. Your thread tension will never work properly unless you pull the thread between the discs.) The pin you're pointing at in the second picture pushes forward and causes the thread tension to be released. My video on replacing the thread tension release guide shows how that pin works: Edited January 3, 2017 by Uwe Quote Uwe (pronounced "OOH-vuh" ) Links: Videos
Members mixmkr Posted January 3, 2017 Author Members Report Posted January 3, 2017 thx again Uwe, Sorry about turning unknown screws!!. Yes I saw it was just a set screw, but I'll always count rotations and such too (coming from working on paper folding machines, inserters...of the era) and yes...the thread is just "laying" on the upper tension disks... it's #138 PTFE thread...so I have to pull it down because the thread is so slippery and have a heavier than normal tension, it seems. It seems that pin is not doing its' job, so will investigate further. Your vid is an involved procedure, but shows what's happening. I'll check it out more, but not sure I want to dismantle as much as you have done in the video! I appreciate all the help as of recent. thx so much Quote JUKI LU562, Singer 107 W1, Thompson PW201 mini walker, a couple of plastic fantastics for light duty "home stuff".... ya know...fixin' and altering clothes.....

Members LumpenDoodle2 Posted January 3, 2017 Members Report Posted January 3, 2017 I can vouch for rule 1.5, and would add the additional sub clause 1.5.3, that all floors, however tidy and uncluttered, will immediatly swallow any, and all screws/spindles/vital componant, whatever size or shape. Never to be seen again, until you have just paid for a replacement. As to Uwe's vid on changing broken tension release bits, I have successfully replaced the thread tension release guide on my Juki, no probs. All due to this vid. Quote “Equality?

Members brmax Posted January 4, 2017 Members Report Posted January 4, 2017 Sometimes just some adjustment can get it releasing correctly or like you want again. It looks like ya have a newer release assembly their. I recall some have a pin in their parts that can get wore, though not sure on that one specific maybe singer I'm remembering. Floyd Quote
Members mixmkr Posted January 4, 2017 Author Members Report Posted January 4, 2017 yeah...that's a newer upper tension assembly. I switched back to my old one. Went I started using PTFE thread, I was having huge problems and thought I'd get a new one. Today has been horrible. Tinkering all day while the sewing jobs pile up. Machine is sewing like crap. Will let a local sewing tech look at it... otherwise, I'm getting something new(er).

Members brmax Posted January 4, 2017 Members Report Posted January 4, 2017 What weight material are you running thru there this week. What seems like the main deal today, but anyway tomorrow is hump day so look ahead. good day Floyd Quote
Members mixmkr Posted January 4, 2017 Author Members Report Posted January 4, 2017 two layers of Sunbrella, a layer of Velcro, using Tenara #138 equivalent and tried needles from #14 up to 20...different bobbins..the usual drill My problems is like Uwe noted in my one picture, the thread doesn't go between the tension disks....or stay there when sewing unless the tension is cranked... Then I'll break upper threads.... loosen it up, birds nest underneath. The lighter Tenara works better...sometimes... Hence asking about the Solarfix. I can't use Dacron thread on my projects. I almost bought a 1508 off Ebay today, but was gun shy. Only $1150 for the shootin match. Need to see what the venders here might do... and maybe take my LU562 in trade? I can't afford a down day like today. Yeah...tomorrow's another day... $0 for today...
