Why Replace It
A worn or bent feed regulator stud causes stitch length to drift or feel inconsistent even when the dial setting hasn’t changed. Replacing it restores accurate, repeatable stitch length control.
FAQ
My stitch length keeps changing on its own — why?
A worn feed regulator stud is a common cause — it lets the feed mechanism slip slightly from your set length as the machine runs.
