This is a part of the needle bar assembly that carries, guides or protects the needle, or leads the needle thread down to it. JUKI includes it in its parts kit for the JUKI LU-2810\/X73178 and LU-2828V-7.\u003c\/p\u003e\n\u003cp\u003eThe needle bar moves the needle up and down in a guided path. Bushings and the parts around the bar keep that path accurate, and the thread guides on the bar lead the needle thread down to the needle. Wear here shows up as needle deflection or skipped stitches. It guides the needle thread down to the needle and keeps the thread from catching on the moving needle bar.\u003c\/p\u003e\n\u003ch3\u003eDetails\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003eJUKI part number: \u003cstrong\u003e40143221\u003c\/strong\u003e\n\u003c\/li\u003e\n\u003cli\u003ePart name: Needle Bar Thread Guide (2810A)\u003c\/li\u003e\n\u003cli\u003eType: Needle Bar Parts\u003c\/li\u003e\n\u003cli\u003eQuantity in the JUKI kit \u003ca href=\"\/es\/products\/juki-40202815-parts-kit-lu-2810-x73178-ja\"\u003e40202815\u003c\/a\u003e (LU-2810\/X73178): 1\u003c\/li\u003e\n\u003cli\u003eQuantity in the JUKI kit \u003ca href=\"\/es\/products\/juki-40202816-parts-kit-lu-2828v-7-ja\"\u003e40202816\u003c\/a\u003e (LU-2828V-7): 1\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch3\u003eFits these JUKI machines\u003c\/h3\u003e\n\u003cp\u003eJUKI's parts kit sheets list part 40143221 for: JUKI LU-2810\/X73178 and LU-2828V-7.\u003c\/p\u003e\n\u003cp\u003eThe machine names are written the way JUKI writes them.\u003c\/p\u003e\n\u003ch3\u003eWhen to replace it\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003eThe needle deflects, strikes the throat plate or hits the hook\u003c\/li\u003e\n\u003cli\u003eSkipped stitches or broken needles that a new needle and resetting do not cure\u003c\/li\u003e\n\u003cli\u003ePlay, noise or heat in the needle bar mechanism\u003c\/li\u003e\n\u003cli\u003eThread catches or frays at the needle bar thread guide\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003cp\u003eSkipped stitches and thread breaks have many causes.
