LED Light Upgrade
The Dritz LED bayonet style lights will not fit the 400 series machines. To make them fit, you need to ream out the socket. You only need to bevel the edge slightly. I used a grinder tip on a drill for about three seconds to bevel the edge.
431G – Removing Broken Needle Plate Pins
After you set the machine on its side and remove the bottom cover of the free arm, you can push the needle plate pins out from the underside. The pin on the right may be obstructed by the feed bar. Adjusting the stitch length to maximum will help you see the hole below the pin.… Continue reading 431G – Removing Broken Needle Plate Pins
431G Needle Plate Pins – Permanent Fix
The needle plate pins for these machines were made from spring steel and were commonly broken. Only a few of the German 400 series machines used these pins and replacements are not available. The following picture shows a with only 3 of the 4 sides of each pin intact. Magnetic Pin Set – Game Changer… Continue reading 431G Needle Plate Pins – Permanent Fix
Attaching the Stitch Plate Cover to the Lid
My original push nut broke when I removed the stitch plate cover from the lid. I ordered 100 4mm push nuts from McMaster Carr for about $15. These fit the cover and I now have 99 to spare. I found the easiest way to install these is with a 1/4-inch or 6mm nut driver. It… Continue reading Attaching the Stitch Plate Cover to the Lid

These chainring bolts are 10mm in diameter and have a small 3 or 4 mm hexagonal hole in the top. They fit well in the… Continue reading 431G Spool Pin Upgrade
431G 120V Conversion
I purchased a 120V Singer 626 on Facebook Marketplace for $40. All the gears in the machine were melted but the motor, wiring, and foot pedal were in good shape. The motor fit perfectly in the 431G and the gear pitch was the same so I did not swap the motor gears. I had to… Continue reading 431G 120V Conversion
431G Stop Motion Wheel
The stop motion wheel on the 431G is made of plastic and will crack over time. I tested a stop motion wheel and washer clutch from a Singer 401a and they fit and worked perfectly. If the wheel ever breaks, I can replace it with the metal parts from a Singer 401a.
My Singer 431G
I was looking for a very rare Singer 431G but the only ones I found were on Etsy and they were priced between $600 and $900 U.S. I took a chance and went to the German version of eBay (eBay.de). I found German language listings that did not appear on eBay.com. I found the following… Continue reading My Singer 431G
