Singer Model 401A Sewing Machine Parts – Original and Replacement

The Singer 401A is a legend for good reason. With a solid metal build and one of the most advanced stitch systems of its time, it remains a favorite among collectors and daily sewists. But like any machine from the 1950s, even this workhorse needs replacement parts to keep going strong.

We stock a mix of tested aftermarket parts and genuine Singer 401A components to keep these machines sewing strong. Whether you're correcting a skipped stitch or replacing internal gears, this collection was built specifically for the 401A.

Why You Need Parts Specific to the Singer 401A

The 401A includes unique features like a built-in cam stack, an internal gear system, and a slant-shank presser foot design. These differences mean that standard parts from other Singer models usually won't fit or function properly.

Every part in this collection has been tested for fit on an actual 401A or pulled from a working donor machine. That means no trial and error, no mismatched components—just the right part for the job. If you’ve ever tried to swap in a cam or bobbin case from a different model, you already know how important exact compatibility is.

What You'll Find in This Collection

We maintain a rotating stock of 401A parts. Due to high demand, some sell out quickly, but our collection often includes:

• Bobbin cases and bobbin winders
• Slant shank presser feet
• Needle plates and throat plates
• Feed dogs and hook assemblies
• And many more!

Each listing includes real photos, clear condition notes, and model compatibility. If you're unsure whether a part fits your machine, just ask. We’re happy to confirm it before you place your order.

Common 401A Repairs and Fixes

Even a durable machine like the 401A eventually needs attention. These are some of the issues customers often resolve using our parts:

• Missing cams that limit decorative stitch options
• Worn gears causing resistance or slipping
• Presser feet that no longer apply even pressure
• Tension assemblies that lead to skipped stitches
• Damaged needle plates disrupting feed motion

Replacing just one of these parts can dramatically improve performance and extend the machine’s life.

Our Quality and Compatibility Process

We clean and inspect every 401A part before listing it. If it’s not pulled from a working donor machine, it’s verified against Singer’s original design specifications. You won’t find guesswork or generic substitutes here.

Each product page includes high-resolution images, measurements, and notes about fit and function. If you’re unsure whether a part is right for your machine, just send us the model number or a clear photo. We’ll help you identify the correct fit before you buy.
