I've had my machine for almost 3 years....never have replaced the hook. I'd search for other causes first. IMHO.

It's starting to struggle with thread breaking problems on designs that sewed fine before and sew fine on the other head. It seems to be especially true right now on smaller stitches. I'm wondering if it's time to replace the rotary hook. I remember all the posts on this subject in the past. How do I search for that info? Thanks, Mike
