Refurbishing the Singer 401 (401A)
|So, are you wondering what I do when I refurbish a Singer 401 or similar machine? This article will give you an overview. You might also enjoy my entry about the Sew-Classic refurbishing process on a Singer 15-91. |
To the left, is the internal, metal cam stack in the Singer 401. It's extremely important to remove all of the old dried up goo, oil, grease and grime from this area. It's very common for the cam stack and it's related components to be so gunked up that the dials on the front of the machine won't even move. As you can see, I have this one spotless and operating perfectly.
|I remove the motor, check the carbon brushes, and make sure the motor is clean and properly lubricated. While it's out I can easily and thoroughly clean the worm gear at the top which drives the machine. As I reinstall the motor, I inspect all the connections and wires.
You can also see that I take apart the tension assembly and clean and polish all the parts. When the tension is reassembled, I fully calibrate the baseline setting. It's failrly common for their to be a layer of grime or sticky film on the tension discs. I also like to check and make sure that there isn't any rust hiding in there either.
I remove the hand wheel in order to clean it and the main shaft and remove any build up grease on the hand wheel gear. I also lightly lubricate the clutch washer to insure optimum performance.
There are other parts that require my attention in the photo and some that I didn't even include in the picture. When I refurbish a machine, I go over it with a fine tooth comb to make it look it's best, and function exactly as it was designed when new.
