It is an elastic metal part that stores force when it is bent, stretched or compressed and gives it back. Kansai Special lists this part in the books of many machine families, among them FX, NR and RX.\u003c\/p\u003e\n\u003cp\u003eA spring supplies the force that a lever, a foot or a thread control needs. When it tires, the setting drifts even though the adjustment looks right.\u003c\/p\u003e\n\u003ch3\u003eDetails\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003eKansai Special part number: \u003cstrong\u003e79-9120-0\u003c\/strong\u003e\n\u003c\/li\u003e\n\u003cli\u003ePart name: Spring\u003c\/li\u003e\n\u003cli\u003eShort form of the number: 79-912\u003c\/li\u003e\n\u003cli\u003eType: Springs\u003c\/li\u003e\n\u003cli\u003eKansai Special parts books that list this part: FX, NR, RX and 7 more\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch3\u003eWhen to replace it\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003eBright wear marks or grooves where the spring rubs another part\u003c\/li\u003e\n\u003cli\u003eEnds that are bent open, worn through or no longer seating properly\u003c\/li\u003e\n\u003cli\u003eRattling or buzzing from the spring area while the machine runs\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003cp\u003eInstall it in the same position and hook it the same way as the old spring, and check the adjustment that depends on it afterwards.\u003c\/p\u003e\n\u003ch3\u003eChoosing the right part\u003c\/h3\u003e\n\u003cp\u003eTo check a coil spring, measure the free length, the wire diameter and the outer diameter of the old one, and count its coils. A stretched or broken spring gives a false length, so rely on the part number in that case. The part number is the safest check: the same number can be used on more than one model.\u003c\/p\u003e\n\u003ch3\u003eMore Kansai Special parts for the same machines\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003e\u003ca href=\"\/es\/products\/kansai-special-79-5220-0-spring\"\u003eKansai Special 79-5220-0 Spring\u003c\/a\u003e\u003c\/li\u003e\n\u003cli\u003e\u003ca href=\"\/es\/products\/kansai-special-79-4270-0-spring\"\u003eKansai Special 79-4270-0 Spring\u003c\/a\u003e\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003cp\u003eBrowse \u003ca href=\"\/es\/collections\/kansai-special-springs\"\u003eKansai Special springs\u003c\/a\u003e, or see \u003ca href=\"\/es\/collections\/kansai-special-spare-parts\"\u003eKansai Special spare parts\u003c\/a\u003e.\u003c\/p\u003e","brand":"PRIZZI SEWING MACHINE CO.","offers":[{"title":"Default Title","offer_id":51105717616805,"sku":"KAN-79-912","price":2.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0658\/7593\/5397\/files\/kp_spring_v2.png?v=1793912248","url":"https:\/\/prizzisewing.com\/es\/products\/kansai-special-79-9120-0-spring","provider":"PRIZZI SEWING MACHINE CO.","version":"1.0","type":"link"}
