Hello,

I'm trying to get an older machine we acquired in working order, it's a TME-DC 906. I have 5 of the 6 heads sewing good but head 4 refuses to sew well. Running an H test the tensions are erratic and tend to pull to one side at times. All needles have been changed with a new hook, all treason discs have been cleaned and tensions feel good yet still issues.

I'm thinking it could be the rotary hook support worn down. It's centered with needle but looks a but rounded. Could anyone provider info if I'm on the right track or ideas on other possible causes?

Thanks,

i find this happens when an accumulation of lint builds up in the bobbin.
Also lubricate your bobbin and make sure the thread is flowing consistently out of the bobbin. This happens to me occasionally when i use certain fabrics that have a lot of lint or dust that comes out of it. and cleaning and lubricating it seems to fix the issue.

I agree. Clean your bobbin case and make sure the bobbin flows evenly. I use canned air to blow out the bobbin area overtime I change the bobbin.

Also your tensioners can build up lint. unscrew them off and clean them. Last resort is the hook.
