Rotary Hook Not Turning on Singer 418?

I have been using a Singer 418 since I found it last year. It is my first and it took me a while to learn to use it, but I finally got there - until I started a project with a stretchy fabric (yesterday). In the last 24 hours I learned lots about needles, puckering, thread breaking, feeding mechanism, presser feet, tension, cleaning, using the right stitches, etc. In the process I solved a few problems, but now I got stuck with one I can't solve on my own: the rotary hook stopped moving.

I opened the base and I can't see any broken gears or belts (see photo).

When I turn the hand wheel, the needle goes up and down normally, the feed dogs move normally, but the hook system stays still. I can move it by hand and it moves smoothly, but it would seem that the part that is supposed to engage the gears in this area is somehow not engaging, and I can't figure out what it is.

I purchased a user manual, but it doesn't cover this. The manual has a picture of the machine with the word 'Stylist' engraved on the front. My machine only has 418 on the front, it doesn't say Stylis (see photo). The bobbin case holder is different from the manual and I could not remove the bobbin case to get to the hook (last photo).

Can you help me with this? I'm not sure which of the screws around the bobbin case holder is the tension screw, but I know I must not 'screw' that! Thank you!

More than likely the silicone gears have worn just enough that the rotary hook will no longer engage. That's going to be a fix for the Singer qualified repair tech - check adverts until you find the ones that say 'Singer factory trained' or 'Singer warranty service approved repairs' - no, your vintage machine is no longer under warranty but all warranty approved service techs will have been exposed to vintage AND modern machines:) The repair will cost you around $50USD (around £30 here in the UK because there are so many salvage parts machines floating about) but splash out and have your vintage machine checked over and serviced - the total for repair and service will bring it in around $90USD (£60-£75 UK).

About your user guide...click this link and go through the free downloads until you find the one that looks EXACTLY like yours:

www.singerco.com/.../search **If you get to the search page instead of the 418 page, key in only the numbers and a page with several models will come up - click till you find your machine:)

The '418 Stylist' was sold in Singer Sewing Centres around the world; the '418' was marketed through Sears - NOT branded as a Kenmore btw, but as a Singer 418). Because yours doesn't say Stylist, it is one of several 418 models (there were variations, a new one every year) and the above link will help you find your correct manual.

Check out Andy Tube on You Tube. He gives a complete course on repairing this broken Singer machine. This 400 Series of sewing machines is notorious for gears that disintegrate with age and too much machine oil dissolving theplastic in the gears. The gear that is damaged is part #155819...the vertical top shaft gear. The video you need to watch is "How to replace the top gear on the vertical shaft singer model 457 and others".

All 400 series Singers have this problem and the repair is basically the same. I just fixed my Singer 478 by putting in the new gear and it works. But you must follow the video from start to finish as the hook timing will need to be adjusted after the installation and Andy will explain. Good luck.
