Mike516 Report post Posted July 17, 2016 I have a Juki 1541S and the part where the needle screws in and the thread goes through just before the needle looks like it's very loose and seems to be bent and possibly breaking the thread. I have added a couple of pictures to try and illustrate the part and where it looks to be breaking the thread. I apologize for the poor picture quality and the 1st grade picture alterations. Should this part be that loose? In the picture with the arrows, are those cracks and would that be causing my thread breakage? My wife needs to keep using it and she's thinking of bypassing that thing for now since it's sunday and there's nowhere open to get a replacement. Is it ok if she goes slowly? I would have looked to see if this has been asked and answered but I can't figure out what that part is called. Thanks. Quote Share this post Link to post Share on other sites
mikesc Report post Posted July 17, 2016 (edited) Yes, that part will affect the thread ( make it break occasionally , and give intermittent tension problems )..it should not be hanging loose( ish ) like that..and the cracks are not supposed to be there..if she goes slow..she may well get away with it..replace the cracked part as soon as possible..keep a "close watch" ( not with your eyes near it ) on it and the screw that goes through it, the thread guide ring that sits on the top of it and the needle in case any of them come loose..Personally I wouldn't use it like that in case something gets loose and causes damage, but..if you have to use the machine ..it is Sunday ..just go very slow and careful, and replace it Monday.. Ps..I'd also advise wearing some kind of eye protection anyway when using a sewing machine, domestic or industrial, ( at whatever speed it is running at even with a servo or a speed reducer or even hand wheeling ) even when nothing is loose etc..a part flying off can do a lot of damage to an eye..and a needle breaking..well, I'll leave anyone who doesn't sew using eye protection to think about the possible consequences of a broken needle tip in the eye..

Mike516 Report post Posted July 17, 2016 Thank you Mike. Is that what it's called, the thread guide ring? Quote Share this post Link to post Share on other sites

Mike516 Report post Posted July 17, 2016 (edited) Awesome thanks so much. I'll be calling my guy tomorrow and ordering a new one. Why would this part bend? Are we doing something that would put pressure on it? Thanks again. Edited July 17, 2016 by Mike516 Quote Share this post Link to post Share on other sites
