{"product_id":"pfaff-bobbin-winder-for-group-d-9111809991","title":"PFAFF Bobbin Winder for Group D | #9111809991","description":"\u003cp\u003eEvery smooth, tension-free bobbin starts with a winder that seats, engages, and releases cleanly. This bobbin winder assembly for PFAFF Group D machines replaces the complete winding mechanism -- spindle, tire contact, and engagement arm -- restoring factory-precise thread lay and consistent bobbin fill. Over time the winder rubber deteriorates and the engagement arm loses its positive click, leading to unevenly wound bobbins, thread tangling, and skipped stitches. Swapping in a fresh assembly brings the winding cycle back to spec without requiring the machine to go in for a bench repair. The part crosses to alternate reference number 91-118099-91 and has superseded earlier Group D service numbers, so it covers a wide span of the PFAFF mechanical lineup.\u003c\/p\u003e\u003cp\u003eThis assembly fits PFAFF Group D machines spanning the classic 333, 335, 481, and 1051 domestic models through the broader mid-generation 242-1426 domestic range, plus select PFAFF 3000-3800 series industrial models -- over 50 confirmed PFAFF machines in total. PFAFF only; no cross-brand fit.\u003c\/p\u003e","brand":"Sewlume","offers":[{"title":"Default Title","offer_id":44254317641816,"sku":"9111809991","price":99.99,"currency_code":"USD","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0603\/4092\/8600\/files\/91-118099-91_01.jpg?v=1793762957","url":"https:\/\/sewlume.com\/products\/pfaff-bobbin-winder-for-group-d-9111809991","provider":"Sewlume","version":"1.0","type":"link"}
