Needle Timing And A Singer 31-15

[pcox]

I have had this same problem. You might try this. Do all these things with the stitch set at the longest stitch. Remove the needle, rotate the machine till the feed dog drops below the needle plate, put a piece of paper under the presser foot let it down. now check to see that is held firmly in place. If it is not, adjust the presser bar lower.

Take the paper out, put the needle in turn the hand wheel till the feed stops moving to the back, the point of the needle should be just ready to enter the material, but the feed dogs should not have dropped below the surface of the needle plate. If the feed dog has dropped thin slick material can slide toward you by the thread tension. This will create more slack than the take up can pull. The feed dog front to back movement is adjusted by he collar on the main shaft. The up & down is adjusted by loosening the screw on the bell crank on left end of the front shaft on the bottom of the machine.

Thanks for your replies, I got my machine to work like the former champ that it was .......not really sure what was wrong but now I feel that I understand the 31-15 pretty well......I also never thought to look at sister machine manuals for information. That was a great idea. Thanks again. blue99, John.

I have bobbin area timing problems with my 31-15. On the Singer 31-15 parts page: 22305 - 1/3, are parts 1266AL set screws? If so, mine are headless and have been turned into pins. Loosening the set screw at the other end of the rod: 453AL, didn't seem to free up anything. I think I need to move the bobbin away from the needle, so adjusting only the needle bar might not fix the timing issue. I'm sorry if I've posted this in the wrong area or if I should have started a new topic thread. Thank you in advance, SharonK

Hello Sharon,

Some of the older 31-15's were pinned & unless the pin breaks it won't go out of time,unless the needlebar gets pushed up when you break a needle.
