Two of these longer M8x57 studs are used alongside the shorter M8x28 studs to provide the threaded mounting points that the cylinder collar nuts (R.242707) engage to clamp the cylinder down. A stripped or snapped cylinder stud is a common rebuild issue — always use correct torque values during installation.\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.940787\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSpecification:\u003c\/strong\u003e M8 x 57mm \/ 20mm engagement\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eTightening Torque:\u003c\/strong\u003e 5 Nm (into crankcase)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eQuantity Required:\u003c\/strong\u003e 2 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 all three Rotax cylinder stud variants alongside the full crankcase rebuild fastener set.\u003c\/p\u003e","brand":"KSG\/Karting Solutions Group","offers":[{"title":"Default Title","offer_id":48168097644765,"sku":"R.940787","price":8.33,"currency_code":"USD","in_stock":true}],"url":"https:\/\/cmckarting.com\/products\/rotax-max-cylinder-stud-m8x57","provider":"CMC Karting","version":"1.0","type":"link"}
