Tension spring for Brother Knitting machine

Carriages of Brother knitting machines have several types of springs to ensure smooth needle handling. This article is about a medium size spring, part of the intricate mechanism of Brother knitting machine carriages. These springs can be purchased in my store.

In particular, this short blog article is about a tension spring responsible for smooth the movement of the middle button on the carriage. (At the end of this article, I show other places in the carriage where the same type of spring can be used). This button is typically used to knit fair isle or/and to reset all other buttons.

To expose that spring, one needs to remove the plastic carriage cover (this step NOT covered in this article) and then remove the metal cover.

For that purpose, remove the two screws marked below.

The plate will then hang by the springs marked in the picture below but they do not have to be removed. Just push the metal plate out of the way. If the springs detach, they are easily to put back. Just take a picture of the agreement before removing the cover.

Once the cover is removed, you will see the springs right away. In my case, one of the springs was simply missing and the mechanism was not retracting automatically the way it was supposed to.

So the replacement spring was placed where one was missing. I made a short video showing where the spring was installed.

“How” the spring was installed is NOT shown in that video because it is kind of hard to capture how to attach the spring. But the loops of the spring need to grab the posts marked in the picture below.

The same spring can be used in positions shown below. The springs marked with crosses are either small/bigger in size or a spring without the loops (springs for the buttons) and thus, cannot be used.
