How to reassemble the tension button - White Sewing 1418 Mechanical Sewing Machine

Test top thread tension. Remove top thread, set tension selector to 4, presser foot up, and needle up. Thread machine up to needle eye. Threading needle eye won't be necessary.


Now make a long slow steady pull of top thread. Thread should advance smoothly without snagging or sudden change of tension. Next lower the presser foot and repeat with long slow steady pull of top thread. Again thread should advance smoothly without sudden change in tension. Note the difference of no tension when foot up and selected tension 4 with foot down.


If you find there is no difference between foot up (no tension) and foot down (selected tension) then tension disc are not working or thread is not between tension discs.

Oops! All sewing machine diagrams/manuals are available, online. Oddly. From the late 1800's, on.

It's far too complicated to explain on here. You need to get a service manual for your model, or find one with a similar dial. Make sure the manual covers tension dials. Getting the spring wound correctly can be a challenge. Have you checked to see the if the presser foot lever is pressing against the tension dial from the inside of the machine?

Depends on the exact construction, but there will be two disks that look sort of like frisbees or dinner plates. They have to face each other, back of the plate to back of the plate, like )( and not like ().

There are just so many kinds of tension control knobs. Do you have a photo or model number?

Go to Singerco.com click the Customer support button and click instruction manuals. White manuals are housed at Singer now. Be sure to enter your model number with a "W" before the number. Hopefully you'll see a picture that will give you a hint on how to reassemble.

If you go to www.searspartsdirect.com you can type in the model of you sewing machine and it will pull up a parts breakdown of your machine. Just look for the section that contains the tension unit. You might be able to reassemble the tension unit once you see all the parts in an exploded view.

Hi,

There is an adjustment on the side of the black bobbin case.

Remove the needle plate, to gain access to the case. Lift it out, noting how it is positioned! On the side of it , there are two screws, one is the adjustment screw - its the one that sits out more. To increase tension, turn it clockwise 1/8th of a turn, reassemble and test sew. (make sure the top thread tension is back to where it should be). Repeat if required. DO NOT adjust too much at a time!

Good luck
