First of all, what in the Sam Hill is that thing sticking out the top of the head? I've never seen any pin like that. Somebody added it to the machine. Second, it appears that you haven't passed the thread through the check spring. You must pull the thread around the tension disks, then feed it through that spring, then up to the take-up lever.

On the manual it showed that it has a pin there but it was missing so I put a bent needle in the hole. It seems to sew better with it than without although now that you mention that it's not going through the spring that might be why. Quote
Members Constabulary Posted June 23 Members Report Posted June 23 (edited) some Singer machines have a crazy thread path and an "odd" / unnecessary thread loop or hole - don´t know why. My 108w20 also has this path and I do not follow it and it works w/o problem. Beside that you have not instated the new tension unit correctly therefore the machine will not work properly. Not much time atm, have to run, more later....

When you have time let me know how it should be. Thank you. Quote

See that round spring pointing straight up on your tension unit? Right at the 12:00 position? It should probably be at about 10:00, straddling the thread. There's some other odd stuff there I won't comment on, but the check spring gets you started. Edit: I think I see a set screw on the side at 5:00. Should be that if you loosen it, you can rotate the check spring into position.

AlZilla Posted June 24 Report Posted June 24 4 hours ago, Calidora said: More like this then? Yep, then the thread would be behind that finger pointing upwards at 11:00. When everything is working right, you'd pull the thread around the disk and them pull it up until it snaps behind the finger. Most threading videos for machines with an exposed tension unit will demonstrate it. On the other side, where the thread enters the tension unit, it ought to be straighter and more taut, but it may just be loosely strung around there in the pic. Making headway.

Members Constabulary Posted June 24 Members Report Posted June 24 (edited) The check spring should rest in ~ the 9 o'clock position. There is a curved metal piece (A) underneath the tension unit that is secured by a screw (B). The end where the check spring rests on should be at approx 9 o'clock and the check spring needs a little pretension so when the thread lever goes down the spring goes back on the rest.

Ok cool Makes sense. When I get home from work I'll do that. Quote
