I purchased a Singer 238k that I have in treadle now. It had option of belt drive motor or treadle. To set up for treadle, all I did was take the belt off the motor and set a treadle belt on the wheel that it came with ( balance wheel with groove for treadle belt). I never thought that I would possibly need to change the wheels because of gears. After reading this blog, I started to wonder if that is needed for my machine too, even if it has a wheel with groove. But if so, too late now since the machine works in the treadle with the wheel that I have.
Thanks for posting this information. It would be fun to find a 401 to treadle, but if you can't locate a 401 then you may want to hunt for a Singer 328K. Have fun!
