Reassembling A Sewing Machine

[amuckart]

Hi all,

I've bought an old 45k21 pretty cheap. It's complete, but not in the best condition. One major problem with it is that the linkage between the main crankshaft and the shuttle carrier bar had been disconnected when I got it. The parts are there, but when I reconnect them something is sticking pretty badly at some point in the rotation of the handwheel.

I'm stripping the machine to clean the rust and gunk off and check the parts for wear etc. I'm taking lots of photographs and notes as I go but because it wasn't fully assembled and running when I got it I have very little confidence that I can get it back together with the timing correct. I know where all the bits go etc and I'm keeping an extensive photographic record of the disassembly so getting it back together intially isn't a problem but how do I get everything back into alignment again?

Assuming a pile of parts and knowledge of roughly how they go together but not the exact rotational relationship between each part on the shaft etc is there a procedure to follow for getting a machine like this running again?

Thanks.

Hi

I assume you have discovered the Singer Manuals at:

http://parts.singerco.com/

Find your model and you can down load the parts book and work manuals for free!

Worse comes to worse you can take the machine to a mechanic who specializes in industrial machines and he can probably put it back in working order.

I just took a Singer 211 apart and if new parts are used you may have to hand lap them to fit. Work on sewing machines is, can be, finicky work and if you goof things up they break!

Good luck

Yes, thanks. I've got the manuals so I can (I hope!) figure out where all the bits are supposed to go again, it's just getting them all in the correct rotational aligment that I'm worried about. Still, I can take it to a professional for that part as you say.

Of course, it's a moot point at the moment because there's one part I simply cannot get to shift so I'm a bit stuck trying to get the thing apart right now
