Four of these nuts are used per engine — one on each cylinder stud. The flanged collar design provides a larger bearing surface than a standard hex nut, distributing clamping force evenly around the cylinder base flange to ensure uniform compression of the base gasket. Using incorrect nuts or incorrect torque on these fasteners causes cylinder tilt, base gasket leaks, and cylinder bore distortion.\u003c\/p\u003e\n\u003cp\u003eCompatible with all Rotax 125 MAX EVO variants: \u003cstrong\u003eRotax 125 Senior MAX EVO, Junior MAX EVO, Mini MAX EVO, Micro MAX EVO\u003c\/strong\u003e.\u003c\/p\u003e\n\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eOEM Part Number:\u003c\/strong\u003e R.242707\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eThread:\u003c\/strong\u003e M8, Collar Flange Nut\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eTightening Torque:\u003c\/strong\u003e 24 Nm, cross pattern\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eQuantity Required:\u003c\/strong\u003e 4 per engine\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFits:\u003c\/strong\u003e Rotax 125 Senior MAX EVO, Junior MAX EVO, Mini MAX EVO, Micro MAX EVO\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003cp\u003eCMC Karting stocks these alongside cylinder studs and all Rotax 125 MAX EVO top-end fasteners.\u003c\/p\u003e","brand":"KSG\/Karting Solutions Group","offers":[{"title":"Default Title","offer_id":48168038236381,"sku":"R.242707","price":8.87,"currency_code":"USD","in_stock":true}],"url":"https:\/\/cmckarting.com\/products\/rotax-max-cylinder-collar-nut-m8","provider":"CMC Karting","version":"1.0","type":"link"}
