Members horselady21 Posted May 17, 2016 Members Report Posted May 17, 2016 Hi, again! After my needle broke last week and then I broke off a piece of the bobbin "hook" (the revolving part that actually holds the bobbin itself), I ordered a new bobbin hook, installed it in the race, and now it has a major sticking problem. The machine spins freely until the new bobbin assembly is installed. Then it is hard to turn. I checked for problems in the race and can't see anything, and it spins freely in my hand but once installed, no go. I ordered a new race assembly but it seems strange that any damage could have been done to such a sturdy part. Any suggestions? And are there any repair shops near Pittsburgh that anyone knows about? Thanks! Quote
Members suzelle Posted May 17, 2016 Members Report Posted May 17, 2016 Just curious, Is this an original Simanco - Singer part? Asking this because I have found that after-market parts can fit very differently. At least that was my experience when replacing that part on the same machine. Just a thought. Quote
Members horselady21 Posted May 17, 2016 Author Members Report Posted May 17, 2016 No, I think it is aftermarket...and I wondered the same thing. Hopefully it will fit the new case better. If not, it may be time to just buy a good used machine from Toledo! Quote
MADMAX22 Posted May 18, 2016 Report Posted May 18, 2016 If you decide to get a new machine and part out or sell your old one I could use a couple of screws for mine. Sorry dont have any input on how to fix the issues. Quote
Members Darren Brosowski Posted May 18, 2016 Members Report Posted May 18, 2016 The hook is made by several companies. The Japanese are the absolute best but there is also an Italian manufacturer. I get some from Taiwan and they have never been a problem. It sounds like the shaft that the bobbin case sits on is out of alignment and it is most likely a one-off problem so ask for a replacement Quote
Members suzelle Posted May 18, 2016 Members Report Posted May 18, 2016 Horselady, What I remember doing with my race assembly (bought an entire new one) was taking some of the parts off the new assembly and putting them together with some other parts that were original and still worked. That was my solution. As far as the Italian maker that the Darren mentioned... Darren, would that be CERLIANI?? If so, agree with you. I have another machine (not a Singer) that has a CERLIANI bobbin in it and I think it's top quality. Will buy more of those! Horselady, don't give up, try whatever you can. You can probably get that machine running smoothly again. Thought you might need a little encouragement to get to the finish line. Quote
Members horselady21 Posted May 18, 2016 Author Members Report Posted May 18, 2016 Thanks, Suzelle! Would you believe, I am actually a formally trained auto mechanic, can take a car apart and put it back together, and this little thing just stumps me sometimes?! I am going to try the new case when it comes next week, and if it still sticks (and if I haven't bought something else yet! So tempted!), I will order a better quality one. The one I bought on ebay said they had sold 12 others so I figured they must be ok. We will see! Thanks for the encouragement! Frustrating when I have so many projects waiting in the wings, and had disassembled the treadle. But I got that almost back together so will play with that while waiting! Quote
Members bootsmt Posted May 18, 2016 Members Report Posted May 18, 2016 You can call Ralph's sewing machine company and ask for help or any of the other repair companies you can find. Sorry I don't have Ralph's number, am at the library. You can find them on the net. I have 2 31-15s nice machines. Quote
Moderator Wizcrafts Posted May 18, 2016 Moderator Report Posted May 18, 2016 I have a 31-15 that gave me kanipshins for a while, jamming the bobbin case as the shuttle turned. I tamed the shrew by a combination of trying different bobbin cases (they vary), backing off the spring pressure screw on the large C shaped spring on the back of the shuttle race (gives more or less clearance for the case and thread) and bending the shuttle driver outward very slightly (more slack = less binding, but slightly iffy timing).

Members horselady21 Posted May 20, 2016 Author Members Report Posted May 20, 2016 I received the new case assembly last night and installed it, and no change...it still sticks with the new hook installed. I reinstalled the old broken hook (as well as I could) and with it, everything spins freely, so I think Suzelle was right...poorly made part. So I found a good used original hook that I bought and will try that. I really hate to call and ask for free help from anyone! Barring anything else, I will drive it over to Toledo! Or just buy a good used one. I came across a post on another site about the exact same situation on the exact same machine though, so I think I am on the right track, and have hope! Quote
