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.
New Motor on Top
I had to wire the foot pedal into the 431G cord.
I eventually purchased an electronic foot pedal to replace the mechanical one and it worked perfectly.
