This is the rotary hook (hook assembly) under the bed that catches the needle thread loop and passes it around the bobbin case.\u003c\/p\u003e\n\u003cp\u003eThe hook works together with the needle, the bobbin case and the bobbin to form the lockstitch. Its point must be sharp and correctly timed to the needle, and its race must be smooth so that the thread runs freely.\u003c\/p\u003e\n\u003ch3\u003eAbout the DLC coating\u003c\/h3\u003e\n\u003cp\u003eJUKI describes the DLC (diamond-like carbon) coating as a coating that makes the metal surface slicker and lowers sliding resistance, so less frictional heat builds up and burn-out of the metal parts is prevented. JUKI says that a longer service life can be expected from it.\u003c\/p\u003e\n\u003ch3\u003eDetails\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003eJUKI part number: \u003cstrong\u003e40166518\u003c\/strong\u003e\n\u003c\/li\u003e\n\u003cli\u003eVersion: DLC coated\u003c\/li\u003e\n\u003cli\u003eStandard version without coating: \u003ca href=\"\/es\/products\/juki-40131956-hook-assembly-t\"\u003eJUKI 40131956 Hook Assembly T\u003c\/a\u003e\n\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch3\u003eFits these JUKI machines\u003c\/h3\u003e\n\u003cp\u003eJUKI's parts catalog lists part 40166518 for: LU-2710, LU-2810-7, LU-2810-7\/X73178, LU-2818-7, LU-2860 and LU-2860-7.\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\u003eSkipped stitches or loose loops on the underside\u003c\/li\u003e\n\u003cli\u003eThe needle thread frays or breaks near the hook\u003c\/li\u003e\n\u003cli\u003eA rough or chipped hook point or race\u003c\/li\u003e\n\u003cli\u003eNoise or heat from the hook area\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003cp\u003eSkipped stitches and thread breaks have many causes.
