Looper for Brother 925D, 929D, 935D, 1034D and 3034D. Compatible aftermarket part. Fitment is taken from the distributor's listing; models not named are not claimed.
This is a replacement upper looper listed by our distributor for the Brother 925D, 929D, 935D, 1034D and 3034D. 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.

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.
Questions about this part
Does this looper fit the Brother 925D?
Yes. The Brother 925D is on the distributor's fitment list for this part, along with 929D, 935D, 1034D and 3034D. 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 Brother part?
No — it is a compatible aftermarket part made to fit the models listed. It is not a manufacturer-original part.
Which looper carries which thread?
The upper looper forms the loops on the top of the fabric and the lower looper the loops underneath. Check which side of your stitch is faulty and replace that looper.
How long does delivery take?
Orders are dispatched from our distributor's US warehouse. We do not hold stock ourselves and cannot promise same-day dispatch; current delivery estimates are shown at checkout, and we will email you if an item is back-ordered.
