Upper Looper for Singer 14U555 (Compatible)

Replacement upper looper for Singer 14U555. The fitment below is taken from the distributor's own listing for this part. It is a compatible (aftermarket) part, not a manufacturer-original part.

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

Loopers are the curved, eyed arms under the needle plate of a serger that carry the upper and lower looper threads and form the overlock stitch with the needles. The point of a looper is precisely shaped; a bent or nicked looper skips stitches and frays thread.

Specifications

How to tell if this is the right one

Loopers are specific to the models listed and to the position — upper or lower — stated. The two are not interchangeable. This is the <strong>upper</strong> position; the opposite position is a different part.

Signs you need this part

Skipped or dropped stitches on one side of the overlock, thread shredding, a visible nick or bend at the looper tip, or the looper eye worn into a groove.

Fitting it

Unplug the machine. Loopers are held by one set screw on the looper shaft. Fit the new looper and check its timing against the needle before sewing — on most machines the lower looper tip should pass just behind the needle scarf at the needle's lowest point.
