Check Spring for Singer 9910, 9920, 9940 and 9960

This is a replacement check spring listed by our distributor for the Singer 9910, 9920, 9940 and 9960.

This list comes from the distributor's listing for this part. If your model is not named, do not assume it fits — check the part you are removing against the specification below, or ask us with your model number before ordering.

What this part does

The check spring (take-up spring) is the small wire spring on the tension unit that keeps the needle thread taut as the needle descends. A broken or weak check spring causes skipped stitches and thread loops at the start of a seam, and is often overlooked.

Specifications

How to tell if this is the right one

Match by the model list. Check springs differ in wire gauge, coil direction and the tail length that engages the stop.

Signs you need this part

Skipped stitches, loops on the top of the fabric, thread breaking as the needle goes down, or the spring's tail visibly broken.

Fitting it

Remove the tension unit, lift the old spring from the stud, fit the new one with the tail against the stop and the coil wound in the same direction.

Questions about this part

Does this check spring fit the Singer 9910?

Yes. The Singer 9910 is on the distributor's fitment list for this part, along with 9920, 9940 and 9960. If your model is not listed on this page, send us the model number and we will check before you order.

Is this the original Singer part?

It is listed by our distributor under the Singer brand name. We describe every part exactly as the distributor lists it and make no claim beyond that.

Pull-up or pull-down?

This refers to the direction the spring tail travels. Match the listing to your machine; the two are not interchangeable.
