Description

The Singer Stitch Length Lever (part # 163951-001), also known as a Stitch Regulator Lever, is a critical control component for vintage Singer domestic sewing machines. This lever allows the user to adjust the number of stitches per inch for precise seam control and often serves as the reverse lever when pushed fully up, enabling reverse stitching for backstitching and securing seam ends.

Specifications:

  • Part Number: 163951-001
  • Type: Replacement 
  • Function: Adjusts stitch length (stitches per inch) and activates reverse stitching
  • Application: Control lever for stitch length adjustment and reverse operation

Machine Compatibility:

400 Series (Slant-O-Matic): 401, 401A, 403, 403A, 404

500 Series (Rocketeer): 500, 500A, 503, 503A

Specialty Models: 431G

Function & Benefits:

The stitch length lever is essential for controlling stitch quality and seam strength. By adjusting the lever position, you can create shorter stitches for delicate fabrics or longer stitches for basting and gathering. The reverse function (activated by pushing the lever fully up) allows you to backstitch at the beginning and end of seams to prevent unraveling, making it a critical control for professional-quality sewing.

Installation Note:

Replace a broken, cracked, or missing stitch length lever to restore proper stitch length control and reverse function. Ensure the lever is properly installed and engages smoothly with the internal stitch length mechanism for accurate adjustment.
