This distortion can lead to uneven main bearing wear and occasionally bearing failure due to insufficient lubrication and overloading of the bearing surface material. Main line bore distortion can also occur in new blocks that have been assembled using high strength case fasteners, which are common in racing and high performance engine builds.\u003c\/p\u003e \u003ceol\u003e \u003ceol\u003e\u003cp align=\"justify\"\u003eWhen an EJ engine requires a repair to remedy a main line bore distortion issue, the labor involved can be tedious and therefore very expensive. The machinist would have to remove material from both sides of the split-block's mating surfaces and  bore or hone back to a STD housing bore measurement so that a standard OD bearing can be utilized. This process also requires and extreme amount of precision and can cause a change in the crankshaft centerline to deck surface distance that would need to be compensated for.\u003c\/p\u003e \u003ceol\u003e \u003ceol\u003e\u003ch3\u003eHousing Bore Spec's\u003c\/h3\u003e \u003ceol\u003e\u003cul\u003e \u003ceol\u003e\u003cli\u003e2.5247\"-2.5255\"\u003c\/li\u003e \u003ceol\u003e\u003cli\u003e64.127mm-64.147mm\u003c\/li\u003e \u003ceol\u003e\u003c\/eol\u003e\u003c\/eol\u003e\u003c\/eol\u003e\n\u003c\/ul\u003e \u003ceol\u003e \u003ceol\u003e\u003ch3\u003eCrankshaft Undersizes\u003c\/h3\u003e \u003ceol\u003e\u003cul\u003e \u003ceol\u003e\u003cli\u003eSTD\u003c\/li\u003e \u003ceol\u003e\u003cli\u003eSTDX\u003c\/li\u003e \u003ceol\u003e\u003cli\u003e.026\u003c\/li\u003e \u003ceol\u003e\u003cli\u003e.25\u003c\/li\u003e \u003ceol\u003e\u003cli\u003e.50\u003c\/li\u003e \u003ceol\u003e\u003c\/eol\u003e\u003c\/eol\u003e\u003c\/eol\u003e\u003c\/eol\u003e\u003c\/eol\u003e\u003c\/eol\u003e\n\u003c\/ul\u003e \u003ceol\u003e \u003ceol\u003e\u003cp align=\"justify\"\u003e\u003cstrong\u003ePlease Note:\u003c\/strong\u003e These are not to be used with NON-MACHINED blocks.\u003c\/p\u003e \u003ceol\u003e \u003ceol\u003e\u003c\/eol\u003e\u003c\/eol\u003e\u003c\/eol\u003e\u003c\/eol\u003e\u003c\/eol\u003e\u003c\/eol\u003e\u003c\/eol\u003e\u003c\/eol\u003e\u003c\/eol\u003e\u003c\/eol\u003e\u003c\/eol\u003e\u003c\/eol\u003e\u003c\/eol\u003e\n\u003c\/div\u003e \u003ceol\u003e \u003ceol\u003e\u003cdiv id=\"newdescrLC\"\u003e \u003ceol\u003e\u003ch3\u003eApplications\u003c\/h3\u003e \u003ceol\u003e\u003cul\u003e \u003ceol\u003e\u003cli\u003e2004-2012 Subaru WRX\u003c\/li\u003e \u003ceol\u003e\u003cli\u003e2004-2012 Subaru STI\u003c\/li\u003e \u003ceol\u003e\u003c\/eol\u003e\u003c\/eol\u003e\u003c\/eol\u003e\n\u003c\/ul\u003e \u003ceol\u003e \u003ceol\u003e\u003ch3\u003eWhat's in the box?\u003c\/h3\u003e \u003ceol\u003e\u003cul\u003e \u003ceol\u003e\u003cli\u003e1 Set of Main Bearings\u003c\/li\u003e \u003ceol\u003e\u003c\/eol\u003e\u003c\/eol\u003e\n\u003c\/ul\u003e \u003ceol\u003e \u003ceol\u003e\u003ch3\u003eWarranty\u003c\/h3\u003e \u003ceol\u003e\u003cul\u003e \u003ceol\u003e\u003cli\u003eKing Limited Warranty\u003c\/li\u003e \u003ceol\u003e\u003cli\u003eFor More Info Contact Us\u003c\/li\u003e \u003ceol\u003e\u003c\/eol\u003e\u003c\/eol\u003e\u003c\/eol\u003e\n\u003c\/ul\u003e \u003ceol\u003e \u003ceol\u003e\u003c\/eol\u003e\u003c\/eol\u003e\u003c\/eol\u003e\u003c\/eol\u003e\u003c\/eol\u003e\u003c\/eol\u003e\u003c\/eol\u003e\u003c\/eol\u003e\u003c\/eol\u003e\u003c\/eol\u003e\n\u003c\/div\u003e \u003ceol\u003e\u003c\/eol\u003e\u003c\/eol\u003e\u003c\/eol\u003e\u003c\/eol\u003e\n\u003c\/div\u003e \u003ceol\u003e\u003c\/eol\u003e\u003c\/eol\u003e\n\u003c\/div\u003e \u003ceol\u003e\u003cdiv class=\"clear\"\u003e\u003c\/div\u003e \u003ceol\u003e \u003ceol\u003e\u003c\/eol\u003e\u003c\/eol\u003e\u003c\/eol\u003e","brand":"King Engine Bearings","offers":[{"title":"Default Title","offer_id":31931196637257,"sku":"KIN MB5740XPG","price":126.96,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/1639\/5151\/products\/King-XPG-Series-OD_005-Oversize-Outside-Diameter-Main-Bearing-MB5740XPG.jpg?v=1744484092","url":"https:\/\/www.mobileigo.com\/products\/king-xpg-series-od-005-oversize-outside-diameter-main-bearing-mb5740xpg","provider":"mobileiGo.com","version":"1.0","type":"link"}
