Needle Chuck Guide Complete (39107-39109)

The S-shaped tongue and metal pin fit together perfectly, so the movement from the operating lever transfers without any wobble. This complete set saved me from hunting down three separate parts—it really does ship as a full kit.

Installed this on my machine last night—the S-shaped tongue aligns much cleaner than the old guide I was using. The whole assembly feels solid, no wobble when I tested the lever movement. Exactly what I needed for precise needle control.

The metal pin slides in perfectly and the S-shaped tongue aligns exactly as it should. My needle bar moves smoothly now without any binding.
