In this video, we remove the reciprocator after exposing the area. To access it fully, we remove the two covers, although only one may be necessary. We then remove the thread take-up lever guide rail by taking out the four straight-slot screws. Because these screws are often secured with Loctite, we use a properly fitting screwdriver and take extra care not to strip the heads. If needed, we add leverage to the screwdriver to help break the screws free safely.
Next, we use a 2 mm Allen wrench to loosen the Allen screw approximately two to two and a half full turns. We do not remove this screw completely, since leaving it in place makes the process easier. We then use a 1.5 mm Allen wrench to pull the wicks out of the reciprocator bar.
To remove the reciprocator, we place the 1.5 mm Allen wrench into the reciprocator bar and twist while pushing upward, continuing to twist and pull until the reciprocator comes free. When installing a replacement reciprocator, we note that the holding bar has one flat side. That flat side must face the left-hand side of the machine, as viewed from the front, so the Allen screw can seat against it properly and hold the reciprocator in place.
When tackling reciprocator service, it’s smart to keep general embroidery supplies nearby for reassembly.
