My Mom was a prolific sewer who had a 401A, I learned to sew by osmosis just being in the same room! I'm not a sewer, but I OCD on the mechanical aspects, taking a dirty hunk of metal and turning it back into a gleaming machine is quite a pleasurable experience!Scott Kohttps://www.blogger.com/profile/02343099283800980897noreply@blogger.comtag:blogger.com,1999:blog-133305403334770394.post-90744035688697577862016-12-06T15:45:13.246-05:002016-12-06T15:45:13.246-05:00I purchased my first 401a last month and fell in l...I purchased my first 401a last month and fell in love, but it had a problem. The bobbin hook position bracket (part 172207) has a pin sticking out of it that Singer decided was a bad idea. They recommended that service technicians remove the pin, but it was hard to get to so they would yank it out leaving rough edges for the thread to catch on as it stitched. This is what happened with mine unfortunately. My service guy caught it quickly and I found an intact replacement part on Ebay. Now that he installed it however, the top thread is breaking at faster sewing speeds. I'm so disappointed and $170 lighter in my pocketbook. It is under warranty, but I'm worried that he won't be able to get it right. Fingers crossed. I'd really like to try sewing on this thing!!Chickadeehttps://www.blogger.com/profile/11195072440198601548noreply@blogger.comtag:blogger.com,1999:blog-133305403334770394.post-4033958471919758522015-07-20T18:40:10.274-04:002015-07-20T18:40:10.274-04:00I can't help you.

By adjusting them, I cured the problem. Few people speak about these clearances. They can be found in the service manual. Hook timing is also important and should checked along with needlebar height as that determines how far down the needle travels...too little and it will miss the hook.

Wrong needle for fabric and thread; bad thread; lint caught in the bobbin case. Start with a universal 130/705H # 80 or #90 Schmetz needle. Get some good thread (Gutterman or Mettler) and check your threading diagram. Fill a high quality class 66 bobbin with the same thread that is on your spool. Check your bobbin threading. It is rare that machines go out of "time" but it is possible Do the simple things first. Then join Vintage Singers Yahoo group and ask for advice there. They are all very smart and helpfulElizabethhttps://www.blogger.com/profile/07285943308096103980noreply@blogger.comtag:blogger.com,1999:blog-133305403334770394.post-50543655568112140442013-07-25T10:56:31.194-04:002013-07-25T10:56:31.194-04:00Hi I have a 401 that I picked up for 15.00.

Now I have a new issue! :\ It's skipping stitches like crazy. Only catching a stitch every inch or so. I'm ready to tear my hair out at this point. I have fiddled with upper and lower tension, changed needles, thread, etc. to no avail. Any tips you may have would be gratefully recieved.Signora Lupohttps://www.blogger.com/profile/07614369308037429105noreply@blogger.comtag:blogger.com,1999:blog-133305403334770394.post-2380022456353536282012-03-12T00:39:13.640-04:002012-03-12T00:39:13.640-04:00I found a 403A this weekend.

The needle position lever was stuck, and the thing that pops up to release the plate was stuck, but we fixed that. All I need now is a stitch length knob doo hickey, which I am working on getting. The motor is still surprisingly fast and strong. I haven't sewn with it yet to test the tension. Maybe tomorrow. I LOVE the 401A. I believe it is one of the best machines Singer ever made. I love the SPEED and strength it has. <br /><br />Have a great week!Michellehttps://www.blogger.com/profile/11994575359990994574noreply@blogger.com
