Singer Class 7-34 Tension Assembly Issues

Recommended Posts

I am repairing a Singer 7-34 which has been previously jury rigged and was missing parts. I have the parts manual to the machine and have gotten original parts but honestly I have trouble figuring out how the assembly goes together. Does anyone have a working 7-34 they could take a close up photo of? Preferably the Tension assembly all put together and one of the assembly broken down in order of assembly?

The check spring stop I have on the machine is not original and I am going to track that down. I took some photos of what I have for the assembly right now. The check spring is new, but I really can't tell based on the manual if it's the right one or not.

Hope someone has some experience with this. It's sewing okay except I have to stop the check spring manualy or it won't form a loop and the bobbin thread isn't getting pulled to the middle.

Cheers!

You need to go around this 1& 1/2x so the thread can grip the roller & the put the thread under the wire after you go through the check spring.

I made a video for a customer who was having the same questions, hope this helps, shows how to thread a seven class from the beginning to the needle.

Cowboy Bob & Gregg, Thank you both for the advice and tips. I got back to the 7-34 today and it is making a much better stitch. I fabricated a stopper for the checkspring out of some aluminum plate until I can track down the original. Now I am finding the stitch length is changing as I sew but I'm not dropping stiches anymore. (One step forward...haha)

I'm sewing scrap leather, two pieces of equal thickness @ 1/8", looks like belt leather to me. The outside walking foot springs back just fine without leather but is erratic when leather is underfoot with and without thread. Someone brazed the foot to the bar so I am wondering if I should lower the feed dogs a titch or see if getting a new spring for the outside foot bar is in order. Or a new bar and foot for that matter.

I'm also missing the teflon protector on the opposite side of the bar but it doesn't seem like that would effect the length?

If you have any ideas on what can be done about that I am all ears. Thanks for the time and attention!
