The bearings keep the crankshaft \u003cstrong\u003ecentered and rotating with as little play as possible\u003c\/strong\u003e, while the seals are responsible for keeping the crankcase airtight so that the pressure and vacuum pulses can correctly move the mixture toward the cylinder.\u003c\/p\u003e\n\u003cp\u003eWhen the bearings begin to develop play, \u003cstrong\u003emetallic noises, vibrations, rough rotation, or crankshaft play\u003c\/strong\u003e may appear.\u003c\/p\u003e\n\u003cp\u003eThe seals are just as critical. A hardened or damaged seal can allow \u003cstrong\u003efalse air to enter the crankcase\u003c\/strong\u003e, causing the engine to run lean, hang at high revs, become difficult to tune, or change its behavior without any adjustment being made.\u003c\/p\u003e\n\u003cp\u003eFor this reason, when the engine is opened to \u003cstrong\u003ereplace the crankshaft, repair a failure, or carry out a complete rebuild\u003c\/strong\u003e, it is worth replacing the bearings and seals at the same time. Reassembling used components around a new crankshaft can compromise all the work carried out.\u003cstrong\u003e\u003c\/strong\u003e\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eFeatures\u003c\/strong\u003e\u003c\/p\u003e\n\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eManufacturer:\u003c\/strong\u003e Athena.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eProduct:\u003c\/strong\u003e crankshaft bearing and seal kit.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eApplication:\u003c\/strong\u003e 2-Stroke engine.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePosition:\u003c\/strong\u003e crankshaft.\u003c\/li\u003e\n\u003cli\u003eSuitable for \u003cstrong\u003eengine rebuilding and maintenance\u003c\/strong\u003e.\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003cp\u003e\u003cstrong\u003eCompatible models\u003c\/strong\u003e\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eFANTIC\u003c\/strong\u003e\u003c\/p\u003e\n\u003cul\u003e\n\u003cli\u003eXE 125 2021-2026\u003c\/li\u003e\n\u003cli\u003eXX 125 2021-2026\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003cp\u003e\u003cstrong\u003eYAMAHA\u003c\/strong\u003e\u003c\/p\u003e\n\u003cul\u003e\n\u003cli\u003eYZ 125 2005-2027\u003c\/li\u003e\n\u003cli\u003eYZ X 125 2020-2027\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"Athena Parts","offers":[{"title":"Default Title","offer_id":67674304250247,"sku":"P400485444118","price":46.46,"currency_code":"EUR","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0860\/6223\/5959\/files\/P400485444118.webp?v=1791972879","url":"https:\/\/motoscoot.net\/en\/products\/crankshaft-bearing-and-seal-kit-yamaha-yz-125-05-27-athena","provider":"Motoscoot","version":"1.0","type":"link"}
